Lee, Ji-Su ; Park, Young-Chun ; Paik, Seung-Woo ; Lee, Sox-Su ; Ahn, Yong-Kun ; Lee, Jong-Soo ;
The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 115~120
To develop a new Gugija(Lycium chinensis Mill) product having increased value, the physiological functionality of various commercial Gugija products were investigated. In addition, an in vivo study was performed using spontaneous hypertensive rats(SHR) to examine the anti-hypertension effects of products. The results showed that antioxidant activity was highest in the methanol extract of Gugija leaf pickle(97.7%), and anti-hypertensive angiotensin I -converting enzyme(ACE) inhibitory activity was 80.4% in Gugija doenjang(soybean paste) water extract. Anti-cholesterolemia HMG-CoA reductase inhibitory activity was highest in the methanol extract of Gugija rice cake(66.1 %). However, SOD-like activity was below 30% in most products; and fibrinolytic activity was not detected or was very weak. Ultimately, we selected Gugija tea and Gugija wine as superior anti-hypertensive Gugija products, and subsequent in vivo testing was performed using SHR, comparing the tea and wine to Gugija fruit. Among them, the Gugija fruit demonstrated the best anti-hypertension effects in SHR.

In a previous study, a mulberry fruit extract(MFE) supplement exhibited anti-inflammatory activity and improved serum lipid profiles in arthritic rats. The objective of this study was to determine whether dietary MFE could ameliorate inflammatory parameters and serum lipid levels in humans. Twenty-six middle-aged subjects(mean body mass index=27
) consumed MFE(100
after lunch for 4 wks. Anthropometric measurements, serum oxidative stress markers and serum lipid profile analyses were performed at baseline and then at 4 wk following the study. There were no significant differences in anthropometric measurements, including BMI, WHR, and body fat composition. After the 4 wk-intervention, serum levels of C-reactive protein(CRP), ferric-reducing ability of plasma(FRAP), serum triglyceride(TG) and LDL-cholesterol had significantly decreased(p<0.05), whereas serum levels of HDL-cholesterol significantly(p<0.05) increased. These findings suggest the consumption of mulberry extract may be protective against inflammation and the atherosclerotic state in elderly obese men at high risk for cardiovascular disease(CVD).

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 135~142
This study investigated to develop new functional yogurt added domestic yuza(Citrus junos). In order to make the most effective yogurt, yuza extract and fructose were mixed at different proportions. DPPH free radical scavenging activity of yuza yogurts increased dependent on concentration. The results of the DPPH free radical scavenging activity, the 1% yuza yogurt was proven to be the best. The overall sensory score for yogurt made from adding 1% yuza ethanol extract was the best of tested yogurts. The antioxidant activity(DPPH free radical scavenging activity) was the highest in 1% yuza yogurt. The quality characteristics of prepared yogurt were evaluated in terms of acid production(pH and titratable acidity), viscosity, color and levels of lactic acid bacteria during storage period. During storage, the quality of yogurt made from adding yuza extract was better than control(without yuza extract). The sedimentation of curd was repressed a little by adding 1% yuza extract.

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 165~175
Pacific saury, Cololabis saira kwamaegi, is a traditional local food of the Eastern sea area centering around Pohang. It is well-recognized as being both tasty and nutritious. Nevertheless, bacterial contamination, excessive dryness, and compositional changes have made it edible only during the winter months. Therefore, to improve its storage, this study examined the effects of storage material, type, temperature, and duration on compositional changes in kwamaegi. The studied samples were kwamaegis that had been dried naturally for 15 days. The storage materials included an A-film, a self-developed multi-film made of polyethylene, polyamide, EVOH, and polyethylene; as well as a B-film made of polyethylene, nylon, polyethylene, nylon and polyethylene. The B films were used after pressing and laminating. The storage types included one whole fish(1G), or 2 divided fish(2G), to increase eating convenience. The 2G type was the muscle portion divided vertically after discarding the jowl, skin, and internal organs. The storage temperatures were
, and the storage durations were 2, 4, and 6 months. Pathogenic bacteria and rheology were measured to observe general compositional changes. The whole kwamaegi showed a total cell number of
CFU/100 g flesh, while the divided Kwamaegi showed significantly greater bacterial numbers at
CFU/100 g flesh. Psychrophils and halophils increased significantly while coliform were not found; the number of mesophils also increased, but not significantly. There were no significant cell number variations between the A-film and B-film. At
, both the A-and B-films resulted in cell numbers of
CFU/100 g flesh, revealing just
of the initial storage levels. Overall, there were no significant differences between the storage materials. Generally, as the storage temperature and duration increased, the moisture content of the kwamaegi decreased. Also, as storage duration and temperature increased, crude protein and crude lipid contents increased; in addition, they increased proportionally as the moisture content of the fish decreased. There were no significant differences in crude ash content with respect to the storage materials, storage temperatures, or storage durations. Finally, there were no significant differences between the kwamaegi samples naturally dried for 15 days and those stored in the B-film vacuum storage for 6 months for strength, hardness, cohesiveness, springiness, gumminess, and water activity.

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 176~183
This study examined the anti-microbiological effects of chlorine treatment on the surface of fresh fruits, in order to improve microbiological safety in school foodservice operations. Non-peeled fruit(strawberries) and peeled fruit(bananas) were treated with different concentrations of chlorinated water and rinsing numbers, followed by microbiological testing. The fruits were immersed at different concentrations of chlorinated water(0 ppm, 50 ppm, and 100 ppm) and durations(3 min and 5 min), and were then rinsed with tap water(one time, two times, or three times). The total viable cell counts of both the strawberries and bananas ranged from
CFU/g, and coliform levels ranged from
CFU/g. As the chlorine concentration, immersion time, and rinsing number increased, anti-microbiological activity increased. The largest microbial reduction was shown with immersion for 5 min in 100 ppm chlorinated water and three rinsings. In the strawberries, this treatment reduced the initial population of total viable cells and coliforms by 3.29 log CFU/g and to an undetectable level, respectively, no total viable cells or coliforms were detected on the banana surface following this treatment. However, after a sterilization treatment with immersion for 5 min in 50 ppm chlorinated water and three rinsings, the total viable cell counts and coliform counts of the strawberries and bananas decreased to acceptable levels, based on the microbiological standards for ready-to-eat foods. Overall, it was shown that the sterilization treatment of 50 ppm chlorinated water, soaking for 5 min, and three rinsings provided an effective reduction in surface microbes, and enhanced the microbiological safety of the fruit.

Soybean powder is a readily available ingredient that is consumed daily as a functional food material. Furthermore, red Ginseng is an herb with various physiological effects. Therefore, in this study, we examined the physiochemical characteristics of Soybean Dasik samples prepared with different amounts of added red Ginseng gel, including Hunter's color values, mechanical characteristics, and sensory qualities. The results of each analysis are as follows. For the soybean Dasik stored at room temperature(
), luminance was reduced as the amount of added red Ginseng gel increased. In addition, Hunter's a and b values were significantly higher in Dasik samples that did not contain red Ginseng gel, as compared to those with increasing red Ginseng gel content. The mechanical properties of the Dasik were also measured at room temperature showing significant differences between samples(p<0.001) for hardness, springiness, cohesiveness, gumminess, and chewiness. In the sensory evaluation, 3 rounds of testing indicated that sweetness acceptance scores were significantly reduced(p<0.001) as the amount of added red Ginseng gel in the Dasik increased. Finally, overall quality was significantly different between the samples(p<0.001) and acceptance scores increased with increasing red Ginseng gel content.

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 190~196
This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). The relative sweetness levels of HFCS, aspartame, acesulfame-K, and glucosyl stevia solutions were examined in comparison to a 10% sucrose solution in a binary solution model. And the sensory properties of ssanghwa beverages containing aspartame, acesulfame-K, and glucosyl stevia were evaluated at the equi-sweetness to HFCS. In the binary solution model, the relative sweetness of HFCS to sucrose was 0.8, while the values for aspartame, acesulfame-K, and glucosyl stevia were 140, 170, and 100, respectively. Sweet taste and sweet after taste were not significantly different between the HFCS, aspartame, acesulfame-K, and glucosyl stevia solutions. On the other hand, bitter taste, first taste, and overall eating quality were significantly different between the HFCS and aspartame solutions and between the acesulfame-K and glucosyl stevia solutions. Finally, the ssanghwa beverages sweetened with HFCS, acesulfame-K, and aspartame only had slight differences in sensory properties. However, the sensory properties of the beverages sweetened with HFCS and glucosyl stevia, respectively, were significantly different.

This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). Sensory scores were examined for ssanghwa beverages containing different levels of glucosyl stevia, aspartame, and acesulfame-K(0, 50, and 100%, respectively) in place of HFCS. The results showed that sensory scores were not significantly different for the beverages containing different levels of acesulfame-K, including aftertaste, ssanghwa taste, and overall eating quality. In contrast, the sensory scores of beverages containing 0 and 100% glucosyl stevia were significantly different. Data were also gathered comparing the sensory scores of beverages according to the different types of sweeteners. Bitter taste and astringency were not significantly different between the beverages sweetened with HFCS, KP(containing 50% acesulfame-K and 50% aspartame), SP(containing 50% glucosyl stevia and 50% aspartame), and SK(containing 50% glucosyl stevia and 50% acesulfame-K), respectively. Finally, aftertaste and overall eating quality were not significantly different between the HFCS and SP sweetened beverages.

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 204~209
The present study examined the ex vivo effect of Job's tear on immune function. Seven to eight week old mice(Balb/c) were fed a chow diet ad libitum two different concentrations (50 and 500 mg/kg BW) of water extract of Job's tear were orally administ every other day for two weeks. The results indicated that macrophage activation had occurred in the mice receiving 50 mg/kg B. W. of Job's tear water extract. Overall, using a mouse model, this study demonstrated that Job's tear extract may enhance immune function by regulating the
and IL-10 cytokine production capacity of activated macrophages in mice. This study may suggest that supplementation of Job's tear water extracts may enhance the immune function by regulating the enhancing the cytokine production by activated macrophage ex vivo.

This study evaluated the hypolipidemic effects of Eleutherococcus senticosus combined with several oriental medicinal herbs. In addition, it addressed whether consuming a diet of healthy food along with a daily supplement of this composite could affect the health status of individuals suffering from diet-related disease such as obesity and hyperlipidemia. The effects of the combined medicinal herbal extracts(MHE) extracted with hot water on reducing serum lipids and improving blood parameters were examined in rats fed a high-fat diet for 5 weeks. Sprague-Dawley rats were randomly assigned to 4 groups: basal diet only(BDG), high fat diet without MHE(FCG), high fat diet and 10% MHE(F10E) and high fat diet and 20% MHE(F20E). Serum lipid contents and blood variables were examined after the experimental period. The results of were as follows. The hematological data for the 4 groups were similar indicating no significant differences. There were moderate level of serum GOT activity in the F10E and F20E groups as compared to the FCG group. Total cholesterol, LDL-cholesterol, triglyceride in serum and the atherogenic index were remarkably reduced in the MHE-supplemented groups as compared to the control group. However, F10E and F20E groups had significantly higher HDL-cholesterol levels than the control group. These results imply that combination of several medicinal herbal extracts could be used to reduce of serum lipid concentrations. The data from this study will be used as basic information with the field of functional food research to address how we can apply oriental medicinal resources to foods. Such research currently drawing considerable attention world-wide.

Mok, Eun-Kyung ; Park, Shin-In ;
The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 218~226
This study examined the preference and consumption of chungkukjang among elementary school children in Seongnam, Korea. The subjects included 583 students(male 300, female 283) who were asked to fill out a questionnaire. The collected data were analyzed using the SAS package. The results showed that 91.9% of the female students, 91.6% of children from nuclear families, and 90.7% of children with stay-at-home mothers, consumed chungkukjang. Among the children who had eaten chungkukjang previously, most had consumed it at home, and 65.5% of the students responded that chungkukjang was tasty. The data also revealed that female students, children from nuclear families, and those with stay-at-home mothers had greater preference for chungkukjang than male students, children from extended families, and those with working mothers. When asked why they dislike chungkukjang, both male and female students who had eaten it responded because 'it smells bad' and that 'it is not tasty'. However, among the students who had never eaten it, the male students replied because 'it is not tasty'(33.3%) and that 'it is not eaten at home'(27.8%), and the primary responses of the female students were 'it is not eaten at home'(65.2%) and 'it is not tasty'(21.7%). However, the subjects who had tried chungkukjang previously answered that in the future they would like to have it more frequently, as compared to the subjects who had never eaten chungkukjang. Therefore, to increase knowledge and improve perceptions of chungkukjang foods, families should give children many opportunities to try them, and in return, children will consume chungkukjang foods with pride. Furthermore, it is important that society as well as mass media, which have great influence on children, show concern and offer support in promoting chungkukjang.

The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 243~255
This study was performed to offer basic data base on traditional Korean festival foods for a traditional Korean food data integration system, that is based on literature reviews. The Korean lunar calendar has seasonal divisions reflecting traditional Korean holidays. In the past, there were many customs corresponding to emotions, and foods were in accordance with customs, festivals, and seasons. Today, we are well aware of the traditional Korean foods of New Year's Day(Seollal), the Korean Harvest Festival(Chuseok), the First Full Moon Day(Jeongwol Daeboreum), the Winter Solstice(Dongji), and the hottest summer day(Sambok). However, many other traditional Korean holidays are disappearing from the modem Korean life-style. This study made the following classifications for traditional Korean festivals. Seollal(Seol), Ipchun, and Jeongwol Daeboreum in January; Junghwajeol in February; Samjinnal in March; Hansik and Chopail in April; Dano in May; Yudu and Sambok in June; Chilseok and Baekjung in July; Chuseok in August; Jungyangjeol in September; Siwolmuoil in October; Dongji in November; and Napil and Seotdal Geumeum in December. The familiar traditional Korean festival foods are as follows: Seollal's festival foods consist of 5 main dishes, 35 side dishes, 12 kinds of tteok lyou, 21 kinds of hangwa lyou, 2 kinds of emchong lyou, and 3 kinds classified as others; this includes tteokguk, manduguk, galbijjim, sinseollo, jeon, pyunyuk, kimch, tteok, sikhe, sujunggwa, fruits, and seju on Seollal. The festival foods for Jeongwol Daeboreum consist of 3 main dishes, 27 side dishes, 5 kinds of tteok lyou, 3 kinds of hangwa lyou, 4 kinds of emchung lyou, and 3 kinds classified as others; this includes ogokbap, mugeunnamul, yaksik, yumilkwa, wonsobyung, guibalgisul, and burum on Jeongwol Daeboreum. The festival foods for Sambok consist of 6 main dishes, 18 side dishes, 4 kinds of tteok lyou, 3 kinds of eumchung lyou, and 2 kinds classified as others; this includes yukgaejang, imjasutang, youngyejjim, tteoksudan, santtalgihwaschae, and subak on Sambok. Chuseok's festival foods consist of 4 main dishes, 22 side dishes, 18 kinds of tteok lyou, 6 kinds of hangwa lyou, 4 kinds of eumchung lyou, and 3 kinds classified as others; this includes oryeosongpyeon, toranatang, garijjim, dakjjim, namuls, tteok lyou, baehwachae, and fruits on Chuseok. The festival foods for Dongji consist of 6 main dishes, 6 side dishes, 7 kinds of tteok lyou, 1 kind of hangwa lyou, 2 kinds of eumchung lyou, and 1 kind classified as others; this includes patjug, jeonyak, and dongchimi on Dongji. Based on these data, it is recommended that knowledge of traditional Korean festival foods be handed down, preserving and develop their excellence and to further scientific studys.

Bae, Yun-Kyung ; Cho, Mi-Sook ;
The Korean Journal of Food And Nutrition, volume 21, issue 2, 2008, Pages 256~262
This study was carried out to compare the hair mineral status of obese, over-weighted and non-obese individuals, to gather basic data for customizing menu development and to create an education manual for the obese persons. Food preferences or various disease states could be suggested by different mineral patterns in TMA(tissue mineral analysis). The results indicated that Zn status was considerably lower in the obese individuals than in the non-obese(p<0.001) whereas hair Na(p<0.0001), K(p<0.01) and Fe(p<0.05) were at significantly higher levels in the obese individuals. The ratio of Ca/K(p<0.001) was significantly lower in the obese than in the non-obese. But the levels of hair toxic minerals such as Sb, As, Hb, Al et al. were not differ according to BMI groups. The obtained data demonstrate the changes of hair mineral content in both overweight and obese individuals thus suggesting metabolic mineral disturbance in those groups.
