  • We prepared Tofu-sulgi by adding tofu and then analyzed the final product in terms of its nutritional quality, rheological characteristics and sensory tests. While the calorie quantity of Sulgi with Tofu was relatively low compared to that of Baeksulgi, it contained the dietary fiber, calcium and iron that were not present in Baeksulgi. Since Baeksulgi holds a large amount of carbohydrates, it shows a higher weight due to its dense fiber. On the other hand, Sulgi with Tofu showed a relatively low level of tofu protein despite the increased amount of tofu protein. This demonstrated the soft characteristics of Sulgi with Tofu. Also, the results of the sensory test showed that Sulgi with Tofu exhibited a higher preference than Baeksulgi in terms of its taste, flavor and fiber content. The preparation method of Sulgi with Tofu in this study used the natural grinding of tofu without removing the moisture. Also the use of both non-glutinous and glutinous rice flour that can be obtained easily in the public market, are convenient due to their characteristics of easy storage and no property change. Therefore, the preparation method of Sulgi with Tofu is quite convenient as compared to that of traditional Dduk (Korean rice cake) including Baeksulgi. From the perspectives of nutritional content, rheological characteristics and taste preference, Sulgi with Tofu fared better than Baeksulgi. Considering the overall quality characteristics of Sulgi with Tofu, we believe that the addition of tofu could contribute positively toward the quality characteristics of Sulgi.

  • A feeding trial was conducted to investigate the effects of the addition of corn distiller's dried grains with solubles (DDGS) to broiler diets on growth performance and meat characteristics. A total of 3,200 d-old, unsexed Cobb-500 broiler chicks were randomly allotted to 16 pens (replicates), with 200 chicks per pen. There were four diet treatments (0, 5, 10, and 15% DDGS), and four replicates per treatment. From 8 to 21 d of age, the birds were fed broiler starter diets containing similar energy (TMEn 3,100 kcal/kg) and protein (21.6%) contents. From 22 to 35 d of age, they were fed grower diets containing similar nutrients (3,150 kcal/kg, 19.5% crude protein). No significant difference was found in growth performances among the four treatments. As the DDGS level increased, the concentration of unsaturated fatty acids in meat increased (p<0.05). The color scores of breast and thigh muscles were not significantly influenced by DDGS, however, the yellowness of shank increased significantly by the addition of DDGS. The hardness of breast and thigh meats was not affected by the addition of DDGS. It was shown that the use of DDGS in broiler diets up to 15% could decrease the feed cost by replacing part of corn and soybean meal, without any negative effect on growth performance and meat qualities.

  • In this survey, we investigated the way of thinking about meal management of housewives including the sincerity to meal preparation, the eating practices and cronic degenerative diseases related dietary behaviors, and studied the effects of above factors on the real food intakes. We also investigated the trends of health-foods and nutrient supplements usage. The results obtained from 506 housewives in Seoul were summarized as follows. Although our subjects prepared their meals habitually without special concern, they did not prefer the use of convenient foods. The food prefrence of housewivess who had more child and refered higher life status was similar with other family members. The dietary attitudes were good in large family, the higher income and the more child group. The highly educated group skipped breakfast more frequently. The mealmanagers with better education career and good living status considered for the restriction of salty foods, sweet foods, animal fats and pungent foods, and for the nutritionally balanced diet. The high income group showed great concerns about weight gain at meal times. The nutritional qualities expressed by the frequency of food group intakes were high in the better educated and living status groups, and their eating frequencies of animal protein foods and calcium sources were significantly high. Mealmanagers who had no job intaked vegetable oils through frying foods frequently. The use of health-foods and nutrient supplements was influenced by age, educational and economic level and self-estimated living status, but the trends in prevalence of both were not consistent. Health-foods were prefered by the groups of high educational career, affluent income and advanced living status, and low educational career, low income and low living status groups favored the nutrient supplements. The restrictive intake of animal fat and the use of health-food were positively correlated, which seemed that the subjects used health-foods as supplements in compensation for nutritional unbalance caused by the avoidance of animal protein foods.

  • Extraction methods for cultured sea mussels Mytilus edulis and the quality characteristics of resulting extracts were investigated. The crude protein, carbohydrate and volatile basic nitrogen content of raw sea mussels was 15.2%, 1.9%, and 11.2 mg/100 g, respectively. Extracts were prepared using three different methods: hot-water extract (WE), scrap enzymatic hydrolysate extraction (SE), and complex extraction (CE). The respective extracts contained 5.5%, 8.6%, and 6.6% crude protein; 281.7, 366.0, and 343.0 mg/100 g amino nitrogen,: and 2.0%, 1.1% and 1.8% salinity. Their extraction yields were 689, 323, and 1,012 mL/kg. The CE method was superior to the traditional WE method in terms of extraction yield, amino-nitrogen content, and organoleptic qualities, but not odor. Active taste components were evaluated and the total free amino acid content of the WE and CE methods was 5,667.0 and 7,006.3 mg/100 g, respectively. The concentrations of major components (for WE and CE methods, respectively) were as follows: glutamic acid (1,244.0 and 955.4 mg/100 g), taurine (987.9 and 746.8 mg/100 g), glycine (721.2 and 847.0 mg/100 g), alanine (341.9 and 423.8 mg/100 g), arginine (265.5 and 376.5 mg/100 g), lysine (199.8 and 270.4 mg/100 g), and proline (253.9 and 220.3 mg/100 g). In conclusion, these results demonstrate that there is potential for using the CE method to expand the commercial utilization of sea mussels as a flavoring substance resource.

  • Two experiments were conducted to study the effects of nutrient level and feeding method of split diets for a.m. and p.m. on laying hen performance. In both studies, ISA Brown layers were kept in laying hen cages and treatments were represented by three or four replicates each containing 25 or 34 birds. In Experiment 1, the control group(C) was fed a conventional single diet throughout the day and split diet groups(T1, T2 and T3) were offered high energy/protein - low Ca diet and low energy/protein - high Ca diets in a.m. and p.m., respectively. In split diet groups, ME and CP consumption, and feed cost required per day and per kg egg mass were significantly reduced(P<0.05) compared to C group, while the hen-day egg production, average egg weight and daily feed intake were not different among treatments. In the second study, C and T1 groups were fed the diets same to the C and T2 groups in Experiment 1, respectively. And T2 group was fed the diet mixed with the split diets for a.m. in mash and p.m. in pellet used in T1 group. In T1 and T2 groups, daily feed intake and average egg weight were significantly reduced(P<0.05), while the hen-day egg production was not influenced by the feeding system. Daily ME and CP consumption, and feed cost were reduced(P<0.05) in T1 and T2, while the ME, CP and feed cost required per kg egg mass were not different to the C group. In both study, eggshell qualities were improved(P<0.05) by split diet feeding. It was concluded the feed and nutrients consumption, feed cost per day or per kg egg mass could be spared by introducing split diets for a.m. and p.m., and the feeding method of mixed diet of split diets was also convenient and effective for sparing feed cost and improvement of eggshell quality.

  • The qualities of the rice straw, black locust and orchardgrass silage added with grape pomace were investigated in this study and the amount of grape pomace added in different treatments were 0, 20, 40 and 50%, respectively. Crude protein contents of rice straw(6.5-10.6%) and orchardgrass silage(13.2-14.8%) added with grape pomace were significantly higher(p<0.05) than that of 100% rice straw(5.3%) and orchard grass silage(12.8%), however the crude protein contents(14.9-15.6%) of black locust silage in supplementation were lower than that of 100% black locust silage(16.3%). With higher amount of addition of grape pomade to rice straw, black locust and orchardgrass silages, ADF, NDF and crude ash contents decreased significantly(p<0.75). Moisture contents decreased according to the higher proportion of grape pomace in the rice straw silages, but increased according to the higher proportion of grape pomace in the black locust and orchardgrass silage. Values of pH in 20∼60% addition of grape pomace in rice straw(4.0∼4.2), black locust(4.1∼4.3) and orchardgrass silages(4.2∼4.4) were lower than that of 100% in rice straw(4.6), black locust(5.4) and orchardgrass silages(4.7). The contents of acetic acid and total volatile fatty acid significantly increased according to higher levels of addition of grape pomace compared to the respective values of silage. However the contents of lactic acid in supplementation of grape pomace were lower than that of 100% black locust silage.

  • This study was conducted to examine the sensory characteristics and the contents of proximate composition and the free sugars of the Demi-glace with varying quantity of Omija extracts added. First, the qualities of Demi-glace sauces with varying quantity of Omija extracts added are as follows: (1) Proximate composition: The moisture content was 66.10~73.50%, and crude ash content was 1.59~1.89%. As the Omija extracts added increased, moisture content increased, whereas crude ash content decreased. The crude protein content was 6.12~7.95%. Among them, the one with the 2% Omija added showed the highest level of the crude protein. (2) Free sugars contents: In terms of total sugar contents, the control showed 1.32% and Omija sauces showed 1.44~1.55%. Major free sugars analyzed in the order of fructose, oligosaccharide, glucose and sucrose. Second, the results of sensory evaluation of Demi-glace sauces with the different levels of Omija added are as follows: (1) The preference of Demi-glace sauces according to occupation: Students and Cooks liked the one with the 2% Omija added in terms of color, flavor, taste, texture and overall acceptability. Cooks showed higher preference than students. (2) The preference of 5 tastes: It was found that Demi-glace sauce with the 2% Omija added was the best. The one with the 2% Omija added was suitable in terms of sweet taste and bitter taste and the one with the 3% Omija added was desirable for hot taste and saline taste. In terms of sour taste, the one with 1% Omija added was regarded as the most desirable one. (3) The preference for authentic tastes for Demi-glace sauce: In terms of simple taste, females showed higher preference than males. Demi-glace sauce with the 2% Omija added was found to be the best for savory taste, flavor enhancer taste, simple taste, after taste and overall acceptability. The one with the 1 % Omija added was regarded as the best for soft taste.
