Quality Characteristics of Noodles Containing Pleurotus eryngii
Sung, Song-Yi ; Kim, Mi-Hyun ; Kang, Mi-Young ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 405~411
This study examined the quality characteristics of noodles prepared with Pleurotus (P.) eryngii paste. Different ratios of P. eryngii paste were added to wheat flour(15%, 30%, and 45%) in the noodle formation. Then, the noodles were evaluated in terms of their cooking, color, texture properties, and sensory properties. The weight and water absorption of the cooked noodles increased with increasing P. eryngii paste content, but the turbidity of cooking water decreased. According to texture profile analyses both the cooked and uncooked and cooked noodles had significant increases in springiness and cohesiveness with the addition of P. eryngii paste. And when compared to the control, hardness and gumminess were significantly lower in the samples containing P. eryngii paste. The lightness, redness, and yellowness of the cooked and uncooked noodles increased with increasing with increasing P. eryngii paste content. Finally sensory evaluation results indicated that the noddles containing 30% and 45% P. eryngii paste had higher quality as compared to the other samples. Overall the results suggest that P. eryngii paste is effective for improving the texture and quality of noodles.

Kim, Mun-Yong ; Chun, Soon-Sil ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 412~418
In this study, Sulgidduk samples were prepared with substitutions of 1, 2, 3, and 4% tomato powder, along with a control, and were then analyzed for quality characteristics such as moisture content, water activity, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of tomato powder in the formulation. According to the results, moisture content and water activity were not significantly different among the Sulgidduk samples. In terms of color, as the level of tomato powder content increased, lightness decreased, while the a-value (+redness/-greenness), and yellowness increased. For the textural characteristics, the samples showed significant differences for hardness, adhesiveness, and gumminess, while fracturability was not significantly different. In addition, the samples containing tomato powder presented significantly higher springiness, cohesiveness(except the 1% substitution level), chewiness, and resilience than the control group. In the sensory evaluation, the control group had significantly higher scores for color and flavor as compared to the tomato powder samples. Furthermore, flavor and overall acceptability decreased, while tomato flavor, sourness, and off-flavor increased with increasing tomato powder content. Sweetness and after-taste were not significantly different among the samples. In conclusion, the results indicate that substituting 2
3% tomato powder in Sulgidduk is optimal for quality, and provides a product with reasonably high overall acceptability.

Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 419~430
The purpose of this study was to investigate the kinds of Tteoks along with their recipes and ingredients occurring in Korean literature published before the 17th century. The reviewed sources included "Sangayorock", "Sasichanyocho", "Soowonjabbang", "Yongjechongwha", "Dongyoebogam", "Domoondaejak", "Geebongyouseul", "New-Guwhangchalyo", "Eumshickdimibang", "Joobangmoon", and "Yorock". Various types Tteoks could be classified into sic groups depending on their cooking methods as follows 23 kinds of Jjjin-tteoks, 8 kinds of Chin-tteoks, 24 kinds of Jijin-tteoks, 6 kinds of Salmeun-tteoks, 4 kinds of Guun-tteoks and 8 other types of tteoks. Within this paper, Tteok recipes and cooking characteristics are discussed and their ingredients, terminology and preparation utensils are reviewed. However some of the Tteok recipes are presently gone or have changed. From this study, we anticipate the development of useful recipes for those who are concerned about health and who seek longevity, and thereby to also advance the culture of Korean rice cakes.

Yoon, Sook-Ja ; Choi, Bong-Soon ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 431~438
This study examined the quality characteristics of Sulgitteok samples prepared with different ratios of lotus root powder over 4 days of storage. The moisture contents of the lotus root powder-containing samples ranged from 35.39 to 37.31% and that of the Sulgitteok without lotus root powder control was 35.92%. The results showed that the various samples had the inconsistent changes during the storage period. As the content of lotus root powder increased, the L-values of samples decreased and the a- and b-values increased. However, their L-, a- and b-values did not show large differences with storage. When compared to the control, the hardness, gumminess, and chewiness of samples slowly increased as the amount of lotus root powder increased. Springiness and cohesiveness decreased according to the amount of added lotus root powder. And increasing amounts of lotus root powder and storage time resulted in greater reductions in adhesiveness. In addition, increasing storage time caused cohesiveness to decrease and springiness to increase. The sensory evaluation results showed that the 20% lotus root Sulgitteok received the highest scores, therefore, this samples was deemed superior.

Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 439~444
This study examined the quality characteristics of soybean curd prepared with the addition of yellow paprika juice. The yield rate, pH, and
, L, a, and b values of the yellow paprika juice were 80.56
0.24, and 26.28
0.27, respectively, and its moisture, crude ash, carbohydrate, crude protein, crude lipid, vitamin A, and vitamin C contents were 93.08 g, 0.40 g, 4.95 g, 0.85 g, 0.02 g, 25.26 IU, and 115.08 mg, respectively. The yield rate of the soybean curd did not differ significantly according to the level of added yellow paprika juice, however, there was a significant decrease in pH and a significant increase in acidity. The
and b values of the soybean curd increased as the amount of yellow paprika juice in the formulation increased, whereas the L and a values decreased. Furthermore, hardness significantly increased as the level of yellow paprika juice increased. In terms of overall acceptability, the preferred soybean curd samples were the control and that containing 10% yellow paprika juice.

Choi, Mi-Ran ; Lee, Sun-Young ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 445~451
This study compared the effects of chlorine dioxide and a commercial chlorine sanitizer for inhibiting foodborne pathogens, including Salmonella enterica serovar Typhimurium, Listeria monocytogenes, and Escherichia coli O157 : H7, on lettuce leaves. The lettuce samples were inoculated with each cocktail of the three strains, and were then treated with chemical sanitizers [distilled water, 100 ppm commercial chlorine and 50 ppm, 100 ppm, 200 ppm chlorine dioxide (
)] for 1 min, 5 min, and 10 min at room temperature(
). Following inoculation of the leaves, initial populations of E. coli O157:H7, L. monocytogenes, and S. Typhimurium were approximately 5.54, 4.47, and 5.12 log CFU/g, respectively these levels were not significantly reduced by the treatment with water,whereas the 100 ppm commercial chlorine sanitizer treatment and
(at all tested concentrations) were effective at reducing levels of all three pathogens. The treatment of 200 ppm
for 10 min was most effective at inhibiting the three pathogens, and reduction levels of E. coli O157 : H7, L. monocytogenes, and S. Typhimurium were 2.28, 1.95, 1.76 log, respectively. The inhibitory effect of
increased with increasing treatment concentration of
, but there was no significant difference by the treatment times. When chemically injured cells of E. coli O157 : H7 and L. monocytogenes and S. Typhimurium were examined by SPRAB and selective overlay methods, respectively, it was observed that the commercial chlorine sanitizer generated greater numbers of injured L. monocytogenes than the
treatment. From the overall results,
was more effective at inhibiting pathogenic bacteria compared to the commercial chlorine sanitizer therefore, it has potential to be utilized as an alternative sanitizer to increase the microbial safety of fresh produce.

Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 452~459
The purpose of this study was to investigate the antioxidative effects of Sea tangle powder(STP) solvent extracts as well as Maejakgwa made with STP. The STP solvent extracts were added to soybean oil at a quantity of 0.05%. The solvents used for extraction were methanol, ethanol, ethyl acetate, and petroleum ether. Soybean oil without added STP was used as a negative control, and soybean oil samples containing 0.02% butylated hydroxy toluene(BHT) and
-tocopherol were used as positive control, respectively. Each sample was stored at
for 30 days. The oxidation levels of these samples were determined by measuring their acid values, peroxide values, and thiobarbituric acid(TBA) values. The soybean oil samples containing the STP extracts had lower oxidation levels than both the negative control and
-tocopherol positive control, and the sample containing the 0.05% methanol extracts had the lowest oxidation. According to the Rancimat method, the methanol extract(320 min) and ethanol extract(316 min) demonstrated longer induction periods as, compared to the control(253 min),
-tocopherol(255 min), and BHT(309 min) samples. For the Maejakgwa, acid values increased over the storage period, however, the samples made with STP had lower values than the control group. Peroxide values increased rapidly for 30 days and then decreased. The TBA values of the Maejakgwa samples made with 3% and 9% STP were lower than those of the 15% STP sample and the control. In conclusion, the oxidative stability of soybean oil containing solvent extracts of STP and Maejakgwa made with STP were increased.

Ji, Eun-Jung ; Yoo, Kyung-Mi ; Park, Jae-Book ; Hwang, In-Kyeong ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 460~465
The objective of this study was to evaluate the antioxidant properties and sensory qualities of citron peel tea, and to determine the optimum ratio of citron peel powder for its preparation. Yuza peel powders were prepared with citron peel tea at weight 2 and 3 g, respectively. Then, color values(L-value, redness, and yellowness), total phenol content, total antioxidant activity, DPPH radical scavenging activity, and sensory characteristics were measured in the tea samples. The pH of the citron peel tea decreased with increasing preparation temperature. And as the amount of citron peel powder increased, total phenol content, antioxidant capacity, and radical scavenging activity increased. The level of total phenolics in the tea had a higher correlation with total antioxidant capacity(
= 0.731). Depending on the level of added yuza powder, significant differences(p < 0.05) were shown for aroma, color, and overall acceptability however, there were no significant differences in sourness and bitterness.

Lee, Mi-Ai ; Han, Doo-Jeong ; Choi, Ji-Hun ; Choi, Yun-Sang ; Kim, Hack-Youn ; Choe, Ju-Hui ; Jeong, Jong-Youn ; Kim, Cheon-Jei ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 466~472
This study examined the quality characteristics of pork patty samples by the addition of hot air-dried Kimchi powder at levels of 0, 1, 2, and 3%(w/w) to the formulation. The CIE
-values of the raw patties decreased with increasing Kimchi powder content(p<0.05), whereas the CIE
-values of samples increased with increasing Kimchi powder content(p<0.05); however, after cooking, there were no significant differences in
-values among the treatments (p>0.05). Due to the acidity of the Kimchi powder, the treatment groups showed reductions in pH; but after cooking, pH had increased(p<0.05). The patties containing Kimchi powder also had decrease cooking losses and reduction of patty diameter(p<0.05). Finally, the results of sensory and texture property analyses indicated that higher overall acceptability and springiness, lower hardness, were attained by the addition of Kimchi powder.

Jung, Kyong-Im ; Shin, Eun-Soo ; Kim, Sang-Ae ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 473~479
The principal objective of this study was to evaluate the sensory properties and physical characteristics of muffins produced using different fats(butter, grape seed oil) and mixing methods(Creaming method, Foam method, Single-stage method). The muffins weighed between
g and were
cm in height. In a texture analyzer test, muffins prepared via the single-stage method with butter evidenced the highest hardness, gumminess, and chewiness values among the five kinds of muffin prepared in these experiments. The springiness value was highest in the muffin prepared via the foam method with grape seed oil. In the sensory evaluation, we detected no significant differences among the muffins in terms of flavor(
), softness (
), and overall acceptability (
). In the chemical composition analysis, moisture and crude protein contents were found to be higher in the control group(p<0.05) than in the muffin prepared via the foam method with grape seed oil(p<0.01). We noted no significant differences among the muffins in terms of crude lipids or crude ash content.
Effects of Coating Syrup with Water-Soluble Extracts of Gugija(Lycii fructus) on the Quality Characteristics of Yukwa
Lee, Kyong-Ae ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 480~486
In this study, Yukwa(YU-G) was prepared by coating in syrup with water-soluble extracts of Gugija(Lycii fructus). The Yukwa samples were stored with PE film packing with air for 12 weeks at room temperature, after which the quality and shelf-life of the Yukwa were assessed. During storage, the moisture contents of YU-G were higher than those of the Yukwa due to being coated in syrup without water-soluble extracts of Gugija(YU-NG), whereas the instrumental textural hardness values of the YU-G were lower than those of the YU-NG. Color determination indicated that YU-NG and YU-G assumed a darker color after storage, becoming both redder and yellower. The peroxide and acid values increased abruptly in the YU-NG during storage, but increased slowly in the YU-G. During the 12 weeks of storage after preparation, the peroxide and acid values of YU-G remained at less than 40 meq/kg and 4 KOH mg/g, respectively. Thus, the experimental method of syrup coating with water-soluble extracts of Gugija rendered the YU-G fairly stable against fat rancidity. The YU-G evidenced generally higher overall acceptability than YU-NG when stored.

Park, Hae-Youn ; Kim, Bok-Wha ; Jang, Myung-Sook ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 487~493
This study examined barley sprout powder on the quality and preservation of Sulgidduk. An optimized formulation (moisture 18.2%, barley sprout powder 2.0% and sugar 14.8%) was first obtained, and then the affect if incorporating the barley sprout powder as a raw ingredients in the mixture was evaluated in terms of Sulgidduk shelf life and quality. For comparison, a control Sulgidduk sample was prepared using the optimized formulation exclusive of the barley sprout powder. After preparation the samples were stored for 3 days at
. The moisture contents of both samples slightly decreased during storage: however there was no significant difference between the samples. Both samples had decreases in colorimetric L- and a-value attributable to the addition of the barley sprout powder as well as storage. Furthermore the treatment sample had increases in yellowness due to the addition of barley sprout powder and storage while the control sample had decreases in yellowness throughout the storage period. The treatment sample had increasing textural hardness, gumminess, and chewiness as the storage period increased. Finally, the treatment sample had a higher total microbial count for aerobes at the beginning of storage: however, as the storage period progressed the control had greater microbial levels. In conclusion the overall results indicate the addition of barley sprout powder has a preservaion effect on Sulgidduk. This data is expected to contribute to the commercialization of high-quality Sulgidduk products with added nutrition and extended shelf life.

Lee, Young-Sook ; Kim, Ae-Jung ; Rho, Jeong-Ok ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 494~500
The principal objective of this study was to assess the quality characteristics of Sprouted Brown Rice Dasik(SBRD) manufactured with various addition levels of honey and Yujacheong(Yuja syrup and Yuja sarcocarp) in accordance with the traditional method for the preparation of Korean Dasik(a kind of cookie). The nutritional components, color value, physical tests, volatile compounds, and sensory evaluation of SBRD to which Yujacheong was added were conducted. The results were summarized as follows. In SBRD to which Yujacheong had been added, the moisture contents and crude fat content did not differ significantly among the sample groups, and the contents of crude protein and crude ash increased with increasing additions of Yuja syrup and Yuja sarcocarp. The pH(p<0.001) and sweetness(p<0.001) were significantly higher in sample D1 than in samples D2 and D4. The L color value was highest in D2, the a value was highest in D3, and the b value was highest in sample D2. The texture property analysis showed that the cohesiveness, springiness, gumminess, and chewiness of SBRD to which Yujacheong was added were all significantly higher compared to sample D1. According to the results of our volatile analysis, the D1 and other experimental groups evidenced different flavors and antibacterial compositions. According to the results of our sensory evaluation, the appearance of the D1 sample was superior to the other samples. However, flavor, taste, texture, and overall preference were higher in the samples to which Yuja syrup and Yuja sarcocarp were added. These results indicate that SBRD to which Yujacheong was added, and particularly those to which Yuja syrup was added, is superior to Dasik prepared with honey in terms of flavor and taste, and this method will improve the flavor and preparation time, due to its lower pH.

Oh, Hyun-Eui ; Hong, Jin-Sook ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 501~510
In this study, we evaluated the quality characteristics of sweet potato Sulgidduk produced with varying amounts of fresh sweet potato, after three days of storage. The more fresh sweet potato was added, the higher were the levels of crude protein and crude lipid; however, crude ash contents were lowest in the control sample, and no significant differences in this value were detected among the samples to which fresh sweet potatoes were added. Moisture contents evidenced a tendency to decrease with increases in the amount of added fresh sweet potato and increased storage time, but pH rose with increases in the amount of added sweet potato. Total cell counts showed a tendency toward decrease with increases in the amount of added fresh sweet potato. L values tended to be low with increases in the amount of added fresh sweet potato and a values were lowest immediately after its production, although no consistent tendencies were noted in correlation with the amount of added fresh sweet potato. b values tended to increase directly with the amount of added sweet potato . With increasing storage time, the L and a values decreased, whereas the b value tended to increase. Upon textural assessment, it was observed that hardness, adhesiveness, springiness, gumminess, and chewiness(all textural components except for cohesiveness) increased with increasing quantities of added fresh sweet potato, and these factors also tended to increase with the progression of storage time. After observation via scanning electron microscopy(SEM), it was noted that the cohesiveness also increased with increasing amounts of added sweet potato. With regard to the sensory evaluation, the samples to which 15% fresh sweet potato had been added evidenced the highest acceptability in terms of color, flavor, and s0weetness, and softness and moistness in these samples decreased with increasing percentages of added sweet potato. It has been previously demonstrated that the addition of 15% fresh sweet potato resulted in optimal overall acceptability. In accordance with the aforementioned results, it has been verified that the use of fresh sweet potato in Sulgidduk is possible and probably desirable, and an addition of 15% sweet potato appears to be the optimal approach in terms of overall quality and functionality.

Lee, Chan-Ho ; Kim, Mun-Yong ; Chun, Soon-Sil ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 511~516
In this study, composite flour and dough were prepared with concentrated sweet pumpkin powder(CSPP) at varying concentrations of 3, 6, 9, 12, and 15%. The samples and a control were then compared with regards to quality characteristics, including moisture, protein, and ash contents, farinogram characteristics, amylogram characteristics, and falling number of flour and extensogram characteristics of dough, in an effort to determine the optimal ratio of CSPP in the formulation. As the CSPP content increased, the moisture and protein contents of the flour increased, whereas the ash contents decreased. With regard to the farinogram characteristics of flour, water absorption, development time, and stability decreased with increasing CSPP content, while weakness increased. The control group evidenced a significantly higher beginning temperature of gelatinization as compared to the CSPP samples. The temperature of maximum viscosity, maximum viscosity, and falling number of flour decreased with increasing CSPP content. With regard to the extensogram characteristics of dough, extensibility decreased with increasing testing time and CSPP content, whereas resistance, maximum resistance, and R/E ratio increased. In conclusion, these results show that
CSPP may prove very useful as a substitute for wheat flour in the production of hardroll bread, and may provide good nutritional and functional properties.
Studies on the Manufacturing and Fermentation Characteristics of Soy-Sauce-Kimchi
Kim, Eun-Jung ; Hahn, Young-Sook ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 517~524
This study made Soy-Sauce-Kimchi and investigated its pH, acidity, microorganism, salinity, chromaticity, viscosity and taste to revive traditional Soy-Sauce-Kimchi using Soy-Sauce instead of salt and to report its fermentation characteristics. As one of studies on traditional Kimchi, it tried for practical use of traditional Soy-Sauce-Kimchi which had been eaten in the middle region of Korea, especially in Seoul but currently has been prepared by only a few people and has disappeared gradually. According to the results of this study, among three groups of Soy-Sauce-Kimchi-I(s1), Soy- Sauce-Kimchi-II(s2) added by 2.5% sucrose and the control group(C), acidity of s2 was sharply increased after 24 hours and 72 hours at
respectively and there was few difference in salinity by temperature. In the case of s2 group, addition of 2.5% sucrose was considered to lead to increase of salinity. For chromaticity, while the L value and b value became larger after 48 hours, the a value tended to decline. Viscosity of s2 grew after 24 hours at all of
and that was thought to be because propagation of bacteria such as Leuconostoc mesenteriodes following addition of 2.5% sucrose secreted dextransucrose so sucrose was transferred into dextran to increase viscosity. The total number of microorganisms was recorded to be largest after 48, 36 and 72 hours at
respectively and the number of lactic acid bacteria was the largest at
after 72 hours compared to those at other temperatures. That was considered to be because microorganisms such as Leuconostoc mesenteriodes are psychrotropic lactic acid bacteria. For sensory evaluation, all appearance, chromaticity and odor of C were higher by
points than those of s1 and s2(p < 0.001) and their feel also showed a similar tendency(p < 0.05). Considering the results of sensory evaluation, more researches were needed to overcome difference of taste for Soy-Sauce-Kimchi according to age due to characteristic flavor and smell of soy-source.

Kim, Yeoung-Ae ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 536~541
In order to determine the effects of strawberry powder on the baking quality of cakes, yellow layer cakes were prepared with four freeze-dried strawberry powders substitutes, at levels of 0%, 1%, 2%, 3%, 4% and 5%. Then, the physical properties, baking properties and sensory characteristics of the finished cakes were assessed. The cakes were stored for 6 days at
and the change in hardness during storage was evaluated. The Viscosity of the doughs, as well as the specific gravity, increased as the amount of strawberry powder in the flour increased. The volume indices of the strawberry powder cakes were less than that of control, but the other indices did not differ from those of the controls. The crust color of the strawberry cakes evidenced a reduction in L. a and b values. The crumb color also evidenced a reduction in the L and b values, but the a values increased. Sensory characteristics were evaluated by 60 students from the Dept. of Food and Biotechnology. Crust color, crumb color, moistness, softness, taste and overall acceptance were measured via a 5-scale acceptance test. The crust color of cakes containing more than 3% strawberry powders and the crumb color of all strawberry cakes evidenced lower scores than the controls. Cakes containing 5% strawberry powders were least acceptable in terms of overall characteristics. Although cakes prepared with flour containing up to 4% strawberry powder were less acceptable than the controls, general sensory scores ranged in an average
like range. The incorporation of strawberry power into cakes was shown to increase the overall hardness.

Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 542~548
In this study, the degree of rancidity and trans fatty acids formation was assessed in Soybean oil(SBO), Corn germ oil (CGO), Canola oil(CNO) and Olive oil(OLO). All samples treated under various conditions were analyzed in order to determine their physicochemical characteristics(RI: Refractive index, Tocopherol, AV: Acid Value, IV: Iodine Value) and total trans fatty acid contents via GC. The results were as follows: The AV of corn germ oil was the highest (0.49
0.01 and 0.72
0.04 respectively) among the 4 kinds of oils at
. The IV of olive oil was the lowest(88.7
0.6 and 89.2
0.5) among the 4 kinds of oils at
. The trans fatty acid contents of the soybean oil, corn germ oil, canola oil and olive oil, respectively(in g/100) increased from 0.41, 0.60, 0.44 and 0.11 prior to heating to 0.84, 1.36, 0.94 and 0.81 after 7 hours. Catechin and BHT reduced trans fatty acid formation by 0.5-15.5% under all treatment conditions. In particular, Catechin exerted a more profound inhibitory effect on trans fatty acids formation than that did BHT.

Lee, Yeon-Jung ; Kim, Sang-Chul ;
Korean journal of food and cookery science , volume 24, issue 4, 2008, Pages 549~559
This study was performed by questionnaire to investigate viewpoints regarding menu excavation and development of native local foods of adults in the Gyeongju area, classified by gender and age. The subject population consisted of 253 citizens(108 males and 145 females) living in Gyeongju. The findings are summarized as follows: The residents highly desired the 'enrichment of service and clean hygiene of local food restaurants', 'active marketing', 'necessity of excavation and development at the present time', and 'development with regional unique characteristics' with regard to the development of the local food choices in Gyeongju, whereas they did not particularly desire 'excavation development of cooking that often is served at family event(birth, marriage, death etc..)', nor 'guidance and enlightenment for many citizens'. The most influential obstacle hindering the development of Gyeongju local food was 'administration support deficiency of connection group agency', followed by 'interest deficiency about local food of restaurant business managers and citizens, different taste of each restaurant', and 'tradition cooking itself is insufficient in Gyeongju'. The most reasonable development menu for native local foods of the Gyeongju area was 'mushroom & beef hot pot(beoseothanu-jeongol)', 'glutinous barley bread(chalborippang)', 'mushroom & bulgogi hot pot(beoseot-bulgogi-jeongol)', 'grilled beef(hanu-sutbul-gui)', and 'grilled minced beef ribs(hanu-tteok-galbi)' in that order. On the other hand, the excavation and development validity scores for 'black goat soup(heukyeomso-tang)', 'gulfweed soup(mojaban-guk)', and 'parboiled octopus(muneo-sukhoe)' were very low.
