Microbiological Hazard Evaluation of the Product Flow of Korean Rice Cakes
Jang, Myung-Sook ; Lee, Hyo-Soon ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 747~755
This study evaluated the microbiological hazard of three Korean rice cake products (Gaepidduk, Injulmi, Julpyon). Microorganisms testing was conducted in various phases of the product flow of Korean rice cakes preparation, food equipment, environment work and cook employees at small scale. The results showed the presence of redbean paste, soybean powder and oil at levels as high as
CFU/g on the hazard analysis of rice cakes ingredients. High levels of coliforms were detected in Julpyon products after 24 hr. and on the cooker's aprons. Clinical bacteria were not detected in any of the rice cakes. We concluded that there is a strong requirement for education related to personal hygiene for the production of hygienic rice cake products and for the publics health.

Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 756~767
This study investigated the attitudes towards business ethics of 409 University students majoring in culinary science and foodservice management. The survey questionnaire evaluated their attitudes by ATBEQ (Attitudes towards Business Ethics Questionnaire), using a seven-point scale and the data were analysed by frequency, t-test, ANOVA and reliability analysis. The average value of ATBEQ was investigated with attitudes towards ethics (3.48
0.79), application of the ethics to business (4.24
0.71), business profit making (4.18
0.71), businessman (4.29
0.67) and practice of business ethics (3.16
0.79). The female, undergraduate and younger students showed significantly higher scores of attitudes towards business ethics (higher ethical attitude) than the male, graduate and older students, respectively. There are some similar results between Korean and Israeli students, while western students (America, Australia and Turkey) showed different attitudes with Korean students.

Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 774~782
Flavor components in fresh Codonopsis lanceolata cultivated on a wild hill were detected by headspace sampling(HSS) method and GC-MS equipped with a VB-5(5% phenylmethyl polysiloxane) column. The 167 volatile compounds that were detected, consisted of 28 terpenes and terpene alcohols, 34 hydrocarbon, 31 alcohols, 13 aldehydes and ketones, 25 esters, 6 acids, 10 ethers and 20 miscellaneous components. The ten major volatile flavor components, comprising about 58% of the total, were dl-limonene (10.2%),
-guaiene (9.0%), 2,2,6-trimethyl-octane (8.6%), hexadecane (8.0%), isolongifolan-8-ol (4.2%), 2,4,4-trimethyl-1,3-pentanediol diisobutyrate (4.1%),
-selinene (3.9%), 2,2,3-trimethylnonane (3.6%), 3-methyl-5-propyl-nonane (3.1%), and ledene (3.1%). The unique aroma of fresh Codonopsis lanceolata described by sensory evaluation was green, earthy, camphoraceous and aldehydic. The components attributed to green or camphoraceous flavor such as 1-hexanol, 2-methylhexan-3-ol, 3-hexen-1-ol, cis-3-hexenyl butyrate, ethylhexanol, hexyl acetate, trans-2-hexen-1-ol, camphor, longiborneol and menthol were not included in the ten or twenty major volatile components which had the largest peak area in descending order. We concluded that the intensity of green and camphoraceous flavor might be used as an indicator of the freshness of Codonopsis lanceolata.

Kim, Sun-Hee ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 783~791
The consciousness and eating habits of the housekeeper directly influence the stress level and health quality of the household occupants. In Korea, most housewives are in charge of dietary life. Accordingly, their attitudinal clusters toward dietary (eating) life were researched in relation to their stress and health. The research results showed that irregular eating habits cause stress. Therefore, it is necessary for housewives to have a regular eating habit. The results were as follows. The house wives' attitudes toward dietary life were categorized into 5 clusters: regular and speedy overeating, regular and frequent eating, regular and light eating, irregular and light eating, irregular and speedy overeating. The cluster of regular and frequent snacks was 24.3%. The cluster of irregular and speedy overeating caused the most stress. Especially the house wives' group belonging to the cluster of irregular and speedy overeating were under social and emotional stress, while the cluster of regular and light eating and the cluster of irregular and light eating were under concentration stress. The cluster of regular and frequent snacks and the cluster of irregular and light eating had negative effect on their health, while the cluster of regular and speedy overeating had negative effect on their family's health by their social stress.

Park, Young-Hee ; Lee, Sung-Sug ; Jung, Lan-Hee ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 799~807
This study was designed to assess the perception and use of weaning diets and to serve as a guideline of processed weaning diets through a survey focused on the Gwangju-Jeonnam regions. The following results were obtained. Most subjects mixed 'home-made' and 'commercial' weaning diets and considered weaning diets as 'a diet for supplementing insufficient nutrition'. The most frequently used type of weaning diet was 'a kind of gruel with vegetables or meat', followed by 'boiling powder with water' and 'grinding or crushing fruits'. Two thirds (68%) of subjects had experienced buying weaning diets, mainly a powder type. The most common reason to buy weaning diets was 'troublesome', followed by 'excellent nutrition', 'convenient to go out', and 'don't know how to make'. The following results according to factors were found. The types of provided and of weaning diets were significantly different by age; the understanding of weaning diets, by education and mothers' employment; and where to get information about weaning diets, by economic status. The highest request for developing weaning diets was a type of 'powder' and 'gruel', and the highest cooking type was 'adding boiling water', followed by 'a semi-cooking product' and 'a finished product'. 'Retort pouch' package, a 'single' package unit, and 'keeping cold' were also requested by the participants. A desirable package unit in developing weaning diets was significantly different by mother's employment; the cooking type of product, by economic status; a way to keep product, by mother's employment; and package types, by education and economic status. When weaning diets were made by environmentally friendly agriculture, 69.5% of subjects were willing to purchase them. With the increase in economic status, education, and employment rate, the use of weaning diets on the market will increase. For this reason, correct nutrition education is needed. With the increasing demand for environmentally friendly agriculture, a variety of weaning diets should be developed to meet this demand.

Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 808~814
The effects of vegetable oils addition on the quality characteristic of pound cake were investigated. The volume of pound cake prepared by adding vegetable oils increased from 1005.8 to 1075.8 mL, compared to 752.8 mL for the control. The volume index of pound cake prepared by adding vegetable oils increased by 3.46
3.65, compared to 2.88 for the control. The hardness and penetration of pound cake with added vegetable oils were decreased significantly compared to those of the control during storage for 72 hours. The texture of pound cake with added vegetable oils was not decreased compared to that of the control. The lightness and yellowness values of the cake increased and the redness values of the cake decreased by adding vegetable oils compared to those of the control. The sensory quality of the pound cake with added vegetable oils, as estimated by color, taste, moistness and overall acceptability, was better than that of the control.

Seo, Min-Ja ; Jung, Su-Ji ; Jang, Myung-Sook ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 815~824
This study was performed to determine the optimum ratio of each ingredient in the steamed foam cake with barley (Hordeum vulgare L.) sproutling powder. The experiment was designed according to the D-optimal design of mixture design, which showed 14 experimental points including 4 replicates for three independent variables (sugar 112
139%, barley sproutling powder 1
8%, and oil 5
25%). The compositional and functional properties of test were measured, and these values were applied to the mathematical models. A canonical form and trace plot showed the influence of each ingredient on the mixture final product. The results of F-test, volume, color values (L, a, b), textural properties (hardness, gumminess, chewiness) and sensory characteristics (softness) decided a linear model, while the sensory characteristics (color, smell, taste, overall acceptance) decided a quadratic model. The volume of steamed foam cake was increased by sugar addition, and a negative effect was exerted by barley sproutling powder and oil. L and a of color values increased but the b value decreased with increasing sugar and oil content, whereas barley sproutling powder tended to decrease all color values. The addition of barley sproutling powder also had a positive effect on the textural properties (hardness, gumminess, chewiness). Sensory characteristics (color, smell, softness, taste, overall acceptance) could suffer counter results with the excessive addition of sugar, barley sproutling powder, and oil. The optimum formulations by numerical and graphical methods were similar: sugar, barley sproutling powder, and oil were 130.4%, 4.0%, and 10.7% by numerical method, compared to 130.4%, 4.0%, and 10.7% by graphical method, respectively.

Kim, Mi-Jung ; Chung, Kwang-Ja ; Jang, Myung-Sook ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 832~839
Kugija was added to Nabak kimchi to improve the quality and preservation and the optimum addition level was assessed. Kugija extract was prepared by boiling kugija fruits, at different ratios (0, 1, 3, 5, 7%; w/v) in water for 30 minutes. The changes in the physicochemical properties of the Nabak kimchi were measured during storage for 25 days at 10?, and compared to a control (without kugija). The pH was decreased in all treatments. Following the fermentation of Nabak kimchi, the total acidity values were inversely proportional the pH changes according to the nature of mutual dependence. However, in short term, during the initial 7 days of fermentation, the total acidity values decreased with increasing concentrations of kugija extract, whereas the trend was reversed after day 10. Total vitamin C content was directly proportional to the concentration of kugija extract and was decreased with the laps of fermentation. Up to day 25, 7% treatment showed the highest vitamin C content, but at 25 days 1% and 3% treatments ranked the first. The mont of reducing sugar was proportional to the concentration of kugija extract however, the difference of values between all treatments became almost indiscernible after day 25. Turbidity values were generally increased in all samples during fermentation period, although only to a limited extent. The lowest turbidity was shown at 3% treatment up to day 16. Total color difference values were increased up to day 16, but then decreased. The optimum level of kugija extract in Nabak kimchi, as determined through these experiments, was between 1 to 3% per added water content, and was preferably 3% for color and fermentation-retarding effect of the product. Kugija extract could be applied for improving the quality and preservation of traditionally prepared Nabak kimchi.

Kwon, Soon-Ae ; Lee, Kwang-Suck ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 864~868
The characteristics of Backsulgi were studied by digital image analysis using CrumScan software. Among many other processing parameters for Backsulgi production, sifting method and levels are important factors for product quality. Traditional and mechanical sifting methods showed a reduction in volume and weight due to air intake during the mixing process. Traditional hand sifting for one time resulted in flour saving for an equal volume of Backsulgi. While mechanical sifting has the advantage of efficiency, the particle fineness shows greater variation than achieved by hand sifting. When using mechanical sifting, hand sifting should be used at least once to improve the product quality such as crumb fineness and product, weight.

Chung, Hai-Jung ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 890~897
The aim of this study was to develop muffins with whey protein concentrate (WPC) substituted for fat at the content of 10%, 20%, 40% or 80%. The quality characteristics were compared with those of a full-fat counterpart. With increasing WPC content, moisture, protein, and ash contents increased, fat content decreased, volume and specific volume of muffin decreased, but weight was unaffected. Crust lightness and yellowness of muffins increased, but redness decreased with increasing amount of WPC. Hardness, cohesiveness, springiness, gumminess and brittleness were the highest in muffin substituted with 80% WPC. Results of sensory evaluation indicated that muffin with up to 40% of the butter substituted by WPC was considered to be as acceptable as the control muffin prepared without WPC.

Kim, Joo-Hee ; Kim, Mi-Hyun ; Kang, Mi-Young ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 898~904
This study was performed to examine the processibility aptitude for the addition of Dobyeong to pigmented rice bran extract. Dobyeong from pigmented rice was less bulky and coarser than Dobyeong-added pigmented bran extract. The viscosity and degree of retrogradation in Dobyeong-added Pigmented bran extract were lower than Dobyeong from pigmented rice, indicating that the inhibitory action of retrogradation was higher in Dobyeong-added pigmented bran extract. The scores for springiness, adhesiveness, cohesiveness, gumminess, and chewiness were increased in Dobyeong-added pigmented bran extract. Dobyeong-added pigmented bran extract showed a decreased natural flavor of pigmented rice and degree of retrogradation, but had higher scores in color values. Dobyeong-added pigmented bran extract was more acceptable in sensory evaluation. Based on these results, the use of rice-added pigmented bran extract instead of pigmented rice in rice-processed food has advantageous effects in terms of the palatability of polished rice and phytochemicals of pigmented non-polished rice. This study will help develop new health-promoting rice products.

Song, Hyo-Nam ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 905~913
The properties of water soluble powder of propolis(WSP), made with different levels(0, 20, 40, 60, 80%) of ethanol extract of propolis(EEP) and hydrocolloid were investigated, along with the quality changes of its bread after 7 days' of storage at
The yield of WSP containing 40% EEP treated at
was the highest at 59.3% and the brown color of all the powders tended to be darkened with increasing EEP content. The turbidity of WSP treated at higher temperature was decreased in its aqueous solution (10%, w/w), and this was considered to be due to the presence of minute nonsoluble particles. Antioxidative activities determined by DPPH(1,1-diphenyl-2-picrylhydrazyl) were the lowest in WSP treated at
, while those of the WSP samples prepared at 160 and
were as high as that of WSP containing more than 40% EEP, regardless of EEP concentration. The propolis breads with added WSP made at
were selected as the most desirable powder for subsequent study. Bread with WSP40 was the heaviest while the volume loss of WSP80 was the greast after baking. The moisture contents of the propolis bread were drastically decreased until 3 days' of storage, but it was thought that WSP might be ineffective for the prevention of moisture loss. The pH of breads without EEP was decreased after 3 days' of storage, while that of the WSP breads remained almost unchanged until 5 days' of storage. Total bacterial counts also exhibited decay levels during the storage. In conclusion, water soluble powder of propolis is useful as a natural antioxidative and antibacterial material in various types of food.

Kim, Ji-Sang ; Kwak, Eun-Jung ; Lee, Young-Soon ;
Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 914~922
Korean traditional rice wines and liquors have been long brewed using nuruk or koji, cooked rice, How, yeast and some medicinal plants or herbs. The rosemary shrub (Rosmarinus officinalis L), belonging to the Labiatae family, is well recognized for its aromatic, antioxidant, antimicrobial and antitumoral properties. In this study, we investigated the effect of rosemary addition on the quality characteristics of Korean traditional rice wine. Wines containing different rosemary concentrations (0, 10, 20 or 30%) were ripened for 0, 5, 10, 15 and 20 days at 25C. The following quality characteristics were compared: pH, total acid, titratable acidity, amylase activity, color, reducing sugar amount, total sugar and ethanol. Although total acid increased, the pH of rosemary wine rapidly decreased during the rot 5-days of ripening, and these two changes were greatest in the wine containing 10% rosemary. The amount of both reducing sugar and ethanol in the wine rapidly increased during the rot 5-days of ripening, while total sugar content of rosemary wine decreased significantly with increasing ripening periods(p<0.05). According to the Hunter's color results, a significant color change in 'L' value was observed with increasing fermentation period in the wine containing 10% rosemary. Although 'a' value of control (0% rosemary liquor) increased during the ripening period, the addition of rosemary did not significantly affect 'a' or 'b' values. The transmittance of rosemary wines increased with increasing rosemary content but decreased throughout the ripening periods. Amylase activity decreased with increasing rosemary content, especially after a 5-day ripening period.

Korean journal of food and cookery science , volume 22, issue 6, 2006, Pages 923~929
Sponge cakes were prepared by replacing wheat flour with rice flour ranging from 10-40% and their physico-chemical, textural and sensory properties were examined. Rice flour addition decreased the moisture content and increased the total sugar and protein contents of the sponge cake. The viscosity and specific volume of batter increased with rice flour addition. 'L' values of crumb of sponge cakes with 20% or more rice flour were lower, whereas corresponding 'a' values were higher than those of the control. Textural hardness was increased, and textural cohesiveness and springiness were decreased with the addition of 30% or 40% rice flour. perceived that sponge cake with 20% or more rice flour had a weaker sweet flavor than the others. With the addition of 30% or 40% rice flour, sponge cake showed a stronger roasted and weaker greasy flavor, and less softness and cohesiveness than the other sponge cakes. The sensory did not find my significant difference in overall acceptability between the control and rice flour-added sponge cakes. Therefore, wheat flour could be replaced by rice flour up to 40% without reducing acceptability.

Classifying Fruits recorded in Tangaekpyeon of Donguibogam and Sikgamchalyo of Jeongjoji of Limwonsibyukji and comparing the types, features, efficacy and side effects based on Kimi Theory(氣味), we found forty one fruits in Donguibogam and forty eight in Limwonsibyukji. As well as fresh fruits, soup, gruel, dry fruit, and powder, peel, stem, leaf, and root were also used. According to the literature, Fruits are classified by five conditions(五氣) and five tastes(五味) and many are mild with sweet taste or warm with sweet and sour taste. They are efficacious in protecting the five viscera, building up energy, controlling heat, calming febrile diseases, promoting urination and excretion, antidiarrhetic, calming cholera morbus, improving skin condition calming the stomach, neutralizing poisonous effects and improving eyesight. To help prevent and cure diseases, those with cold physical constitution must take warm Fruits to vitalize their physiology and those with hot physical constitution cold Fruits for balance. To improve their physical health, our ancestors tried to control their bio rhythm with food and medicinal material and promoted health and prevented diseases by taking such food. We therefore expect that we can have a healthy dietary life by taking advantage of the five conditions and five tastes of Fruits and continuing the spirit of Korea traditional food culture.

The objective of this study was to develop black sesame gruel with high-dietary fiber rice, 'Goami 2'. Physical and sensory properties of black sesame gruel with various ratios of black sesame by weight (20, 40, 60%) and various water volumes(1100, 1200, 1300 mL) were investigated using colorimeter, consistometer, viscometer, sensory evaluation panel and consumer evaluation. The black sesame content significantly(p<0.001) affected the mechanical characteristics(color, consistency and viscosity), sensory characteristics(blackness, glossy, nutty, astringent taste, bitter taste and viscosity) and sensory acceptance(color acceptance, taste acceptance, viscosity acceptance and overall acceptance). The water content significantly(p<0.05) affected the mechanical characteristics(consistency and viscosity), sensory characteristics(viscosity) and sensory acceptance(taste acceptance, viscosity acceptance and overall acceptance). In the black sesame gruel, as black sesame weight ratio increased, the brightness, redness, yellowness and viscosity were decreased while the consistency, blackness, glossy, nutty, astringent taste and bitter taste were increased. In the sensory evaluation results, the optimal material mixing ratio for gruels was black sesame : Goami 2 = 40(80 g) : 60(120 g), water 1200 mL.

Eleven rice varieties, five normal-yielding and six high-yielding, were examined for proximate composition, mineral and fatty acid composition, and antinutrients. The proximate rice compositions for moisture, crude protein, crude fat, carbohydrate, crude fiber and crude ash were 10.70
0.73% and 0.31
0.91%, respectively. The proximate composition of the various rice varieties was not significantly different except for moisture and carbohydrate. The contents of saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acid of the rice varieties were 22.45
44.99% and 32.01
46.02%, respectively. Several high-yielding rices varieties had higher oleic acid or linoleic acid. Ilmi and Nampyung had high oleic acid contents at ever 40%, and Dongjin No. 1, IlPum, Junam and Seachuchung had high linoleic acid contents at over 37%. The major minerals of rice were K and Mg and their respective contents were 85.62% and 25.55%. High-yielding rice varieties had significantly higher Mn and Na contents and lower Mg and Fe contents than normal-yielding rice varieties (p<0.05). Antinutrients such as lectin, phytic acid and trypsin inhibitor were not detected in any of the rice varieties.

This research was conducted to examine the usability of Dangui (Angelica gigas Nakai, Root) and Seungumcho (Angelica gigas Nakai, Leaf) as functional food in aspects of their functional components and nitrite scavenging ability. Analysis of proximate composition showed that Dangui contains more moisture, crude lipid and crude protein than Seungumcho. On the other hand, Seungumcho contains more than twice mont of crude ash and crude fiber than Dangui. Dangui showed higher contents in phosphorus, iron, magnesium, and Seungumcho showed higher contents in copper, calcium, sodium, potassium compare to each other. Substances such as calcium, magnesium and iron that showed high contents in Dangui and Seungumcho are the most important inorganic substances. Total dietary fiber(TDF) of Dangui, sum of IDF and SDF, was 24.2%, and Seungumcho showed 28.18%. vitamin C contents of a 29.690.33 mg/100g appeared only in Seunggumcho. Total phenol contents of Dangui was 0.100
002% and that of Seungumcho 0.0900
008%. Nnitrite Scavenging ability of both water soluble and methanol soluble extracts were more than 90% at pH 1.2, and it decreased as pH level adjusted to pH 4.2, pH and 6.0.
