During two years, four samples per year were collected in Vietnam from rice bran, cassava residue, brewer's grain, tofu residue, soybean meal, coconut cake, sweet potato vines and water spinach for chemical analysis and assessment of water holding capacity (WHC). The selected feedstuffs represent fibre-rich plant sources and agro-industry co-products commonly used in pig feeding in Vietnam. The content (g/kg DM) of crude protein (CP), ether extract (EE) and non-starch polysaccharides (NSP) varied between feedstuffs and ranged from 21 to 506 for CP, from 14 to 118 for EE and from 197 to 572 for NSP. Cassava residue had a high starch content of 563 g/kg DM, while sweet potato vines, water spinach, coconut cake and soybean meal had a high content of sugars (63-71 g/kg DM). The content of individual neutral sugars varied between feed ingredients, with the highest content of arabinose, galactose and glucose in tofu residue, the highest content of xylose in brewer's grain and the highest content of mannose in coconut cake. The content of uronic acid was high for cassava residue, tofu residue, sweet potato vines and water spinach (57-88 g/kg DM). The content of soluble non-cellulosic polysaccharides (S-NCP) was positively correlated ($r^2$ = 0.82) to the WHC. The content (g/kg DM) of CP, NDF, neutral sugars, total NSP, total NCP, S-NCP and total dietary fibre in tofu residue, water spinach and coconut cake varied (p<0.05) between years. In conclusion, diet formulation to pigs can be improved if the variation in chemical composition of the fibre fraction and in WHC between potential feed ingredients is taken into account.

Preferences of 814 elderly living in Incheon for dishes, food materials and cooking methods were investigated. The survey was conducted from Dec. 2000 to Jan. 2001 by questionnaires. Subjects preferred cooked rice with beans, kalkooksoo(hot noodle), gomtang(soup with beef), bibimbap(rice with assorted mixture) to other staple dishes. However, preference for hashed rice or curried rice was very low. More than 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 68.7%. There was no significant difference in preference for pan-fried foods according to food materials in them. Subjects liked injolmi(waxy rice cake), shikhye(fermented rice drink) and coffee the most. Most subjects preferred plant foods like vegetables, legumes and seaweeds to animal foods. Preference of elderly for milk and yoghurt was reatively high; however, that for ham, butter and cheese was low. Elderly in Incheon liked roasted beef, beef soup and roasted pork the most. Chicken was preferred when it was boiled in water with garlic, ginseng, and so on. Cooked and seasoned vegetables (Namul) were the most preferred type by elderly. Preferences for dishes and food materials were more affected by living places of the subjects than by sex, and the reverse was true in preference for cooking method of food materials.

Jeupjang like salted soybean paste with vegetable is the Korean traditional side order eating at table. Bibliographical studies on the Jeupjang in historic books such as Jeungbo-Sanlim-Keongjae(Re-edition of agriculture economic), Imwon- Keongjae Ji(Book of country economic) and Keuhap-Chongseo(Handbook of household) described the Korean food in the 18 century carried out. In addition, investigation and analytical studies on various home-made Jeupjang in present was accomplished. Jeupjangs were classified into three types according to variety preparing methods. Three types were fermented soybean paste (Doenjang) type using traditional Meju(soybean cake stater) for Jeupjang, salted pickle (Jangachi) type buried cucumber and eggplant into soybean paste or soysauce (Kanjang), and salted sauer kraut (Kimchii) type prepared vegetable in Jeupjang-Meju mash. The procedures for producing Jeupjang were Jeupjang-Meju making, and mixing vegetable with Meju powder into brine. At last process was fermented in horse wastes or grasses for 7-14 days. But manufacturing methods of Jeupjang before the 18 century were different in present. Nowadays glutinous rice, red pepper powder and various vegetable were used for domestic Jeupjang.

Dietary pattern analysis is important complementary approach for identifying associations between diet and chronic disease. A case-control study was conducted in order to examine dietary patterns and the risk of colon cancer in Korea. Data were collected from both 137 cases with either colorectal cancer or large bowl adenomatous polyps and 134 controls regarding social-demographic characteristics and food intake using a semi-quantitative food frequency questionnaire. We conducted factor analysis and identified 6 major dietary patterns: 'Well-being diet' characterized by higher intakes of potatoes, yogurt, soybean paste and vegetables, 'Meat & fish', 'Milk & juice', 'Pork & alcohol', 'Rice & kimchi', and 'Coffee & cake'. We calculated factor scores for each participant and examined the associations between dietary patterns and colon cancer risk. After adjusting for potential confounders, there was a relative risk for colon cancer of 0.16 (95% confidence interval, 0.07 - 0.34) when comparing the highest with the lowest tertile of the 'Well-being' pattern. Significant trends of decreasing risk of colon cancer also emerged with the 'Milk & juice' (OR = 0.40, 95% CI = 0.20 - 0.79). In contrast, inverse associations of the risk were found for 'Pork & alcohol' (OR = 1.92, 95% CI = 0.93 - 3.97), 'Coffee & cake' (OR = 2.18, 95% CI = 1.07 - 4.46). For the 'Meat & fish' pattern, the decreased risk of colon cancer was observed in the second tertile, but not in the highest tertile when comparing to the lowest. The 'Rice & kimchi' pattern had a nonsignificant association with the risk. These data suggest that major dietary patterns derived from the FFQ associated with the risk of colon cancer in Korea. Since foods are not consumed in isolation, dietary pattern research in natural eating behavior may be useful for understanding dietary causes of colon cancer.

The effects of four different oligosaccharides with 2, 4, 6% (w/w) (fructo-oligosaccharide, xylo-oligosaccharide, chito-oligosaccharide and soybean-oligosaccharide) on gelatinization and retrogradation of sulgidduks (Korean rice cake) were examined. The amylograph results of rice flour showed that chito-oligosaccharide hastened gelatinization, and delayed retrogradation. Blue value results of chito-oligosaccharide added sulgidduks showed retarded retrogradation during storage (1, 2 and 3 days). Chitooligosaccharide and xylo-oligosaccharide added sulgidduks showed significantly lower hardness during storage. Lightness (L) decreased and redness (a) and yellowness (b) increased with increasing oligosaccharide amounts. In the sensory evaluation of sulgidduks, color of fructo-oligosaccharide added sulgidduks obtained the highest score among oligosaccharide added sulgidduks. During storage, xylo-oligosaccharide and fructo-oligosaccharide added sulgidduks had higher flavor, taste, graininess and overall quality scores than the control. Physicochemical tests showed that chito-oligosaccharide retarded retrogradation, whereas chitooligosaccharide- added sulgidduks had low scores in sensory tests due to aftertaste of chito-oligosaccharide. To improve the sensory quality of chito-oligosaccharide added sulgidduks, mixtures of chito-oligosaccharide with xylo-oligosaccharide and fructooligosaccharide were applied at ratios of 3%:3%, 2%:4% and 1%:5%, respectively. The addition of chito-oligosaccharide and xylo-oligosaccharide at ratios of 2%:4% and 1%:5% to sulgidduks showed relatively high scores in the sensory evaluation retarding retrogradation.

Jeung-pyun, a very popular fermented rice cake consumed in Korea, consists mainly of rice, rice wine (Tak-Ju), and sugar. The effects of addition of different beans on the quality characteristics of the batter and Jeung-pyun were investigated. Six different beans were mixed with the rice flour at levels of 5% and 10% of the rice flour weight, respectively. The addition of Back-tae, Huk-tae, Sori-tae, which are types of soybeans, and black gram significantly increased the batter volume and viscosity. However, the fermented Back-tae (Cheongguk-jang) was not effective at increasing the batter volume and viscosity. The buffering effect of the beans was very significant on the fermented batter, and the decrease in pH of the fermented batter made with beans was less than that of the control batter without beans. Additions of the soybeans and Cheongguk-jang were most effective for the buffering effect in the fermented batter. Although the Back-tae, Huk tae, and Sori-tae were different colors and shapes, they were all soybeans and exhibited similar effects on the Jeung-pyun batter. However, the effects of the beans were not significant on the Jeung-pyun. The volume and moisture content of the Jeung-pyun made with beans were not significantly different from the volume and moisture of the Jeung-pyun made without beans. The above results suggest that the addition of different soybeans, mung beans, and black gram significantly effects on the properties of Jeung-pyun batter, but not Jeung-pyun itself.
