Experiments were performed using sweet potato starch-wheat composite flours to study the rheology and baking properties of bread with composite flours and to test sensory characteristics. Doughs were prepared from mixtures containing wheat flour and 10, 20, and 30% of sweet potato starch(SPS). Standard methods were used to evaluate the rheology and characteristics of wheat composite flour. The results were as follows : 1. The water absorption, developing time and stability measured by farinograph tended to decrease as SPS contents increased. 2. As the contents of SPS increased, the maximum viscosity of the composite flour by amylograph increased, yet gelatinization temperature was slightly low. 3. In the extensograph, extensibility decreased but the ratio of resistence to extensibility increased in proportion to the contents of SPS. 4. In the quality scoring of the bread, WF, WF + SPS 10%, WF + SPS 20% and WF SPS 30% were 84, 80, 77, 73, respectively. Specific volume and crumb characteristics of bread became inferior as SPS contents increased.

Toxohormone-L is a lipolytic factor, found in ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. A substance that inhibited the lipolytic action of toxohormone-L was isolated from white ginseng powder. This substance was an acidic polysaccharides. It inhibited toxohormone-L-induced lipolysis in a dose dependent manner at concentrations higher than 10㎍/㎖.

Nangmyun-broth was collected as samples from 25 common restaurants in Bucheon to examine it`s sanitary condition. The main course of bacterial contamination was persuited for it`s sanitary improvement. Bacterial count in summer sample was not greatly different from that in winter, resulting in total count 1.7×10 exp (7)/㎖, lactic acid bacteria 8.7×10 exp (6)/㎖, coliform group 1.2×10 exp (5)/㎖, Staphylococcus aureus 6.5×10 exp (2)/㎖. Bacterial contamination occurred remarkably with the use of storage barrel in which remnent Nangmyun-broth was still resting, because the remnent Nangmyun-broth contained high level of bacteria. Good santary condition in Nangmyun-broth was obtained by the use of clean barrel which had been washed with tap water or sterilizied with steam before filling fresh Nangmyun -broth for cold storage. The growth of Escherichia coli and Staphylococcus aureus was inhibited in the presence of acetic acid(0.01∼0.05%) or mustart(0.1∼0.5%).

This study carried out to changes α-amylase activity and isozymes in barley during germination in the dark and red light. The specific activity of α-amylase was increased during the germination periods in the dark, giving 355.0 and 523.7 units/㎎ protein at 3 and 5 day, and the activity was increased by the red light up to 48 and 15% at 3 and 5 days of germination, respectively. The ratio of α-amylase Ⅰ and Ⅱ was approximately 95 : 5 at both 3 and 5 days of germination in the dark while the different ratio was found by the red light i. e. 60 : 40 and 90 : 10 at 3 and 5 days of germination, respectively.

For the purpose of the production of single cell protein from rice bran oil, yeast was isolating from soil. It was belonging to Candida albicans species. These experiments were conducted to find out the property on yeast cell from rice bran oil. Molecular weight for the main protein on yeast cell protein from rice bran oil seperated by 1% SDS polyacrylamide gel electrophorosis was 22, 000.

The effects of six kinds of phosphate complex on the water holding capacity (W.H.C) and protein solubility of hair tail, yellow tail runner and dried pollack meat paste were investigated and animal meat(pork, chicken and hare meat complex). The formulation of six kind of phosphate complex employed to this experiment were made by mixing several phosphate such as sodium polyphosphate, sodium pyrophosphate, sodium acid pyrophosphate, potassim pyrophosphate, sodium ultra-meta-phosphate, sodium-tetra-phosphate and monoglyceride at different mixture ratio. Among the six kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium polyphosphate 40%, sodium pyrophosphate 30%, sodium tetra mata phosphate 10%, sodium ultra meta phosphate 10% was most effective on enchanging the W. H. C. and protein solubility of hair tail, yellow tail runner dried pollack meat past and in case of pork, chicken and hare meat paste. Phosphate C complex which was formulated by mixing sodium polyphosphate 50%, sodium pyrophosphate 30%, sodium tetra meta phosphate 10%, potassium pyrophosphate 10%, was more effective them other phosphate complex, and thier optimum addition level was 0.5% respectively in weight of fish meat paste. Texture characterstics such as hanrdness, cohesiveness and springiness value of Kamaboko(fish meat and pork, chicken, hare meat complex past meat product) were evaluted as best when 0.5% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 20 minutes at 120℃.

In order to obtain the fundamental informations on cellulase of Trichoderma viride QM 9414 for its production and utilization, some physico-chemical properties of the enzyme were reviewed. When T. viride QM 9414 was cultured on wheat bran medium, filter paper-disintegrating and carboxymethyl cellulose(CMC)-saccharifying activity were incresed with the cell growth, and thereafter CMC-saccharifying activity was kept on almost the same leved while filter-paper disintegrating activity was decreased sharply. And β-glucosidase was formed maximally on the late stationary phase of growth. The crude cellulase of cell-free extracts was purified by (NH_4)_2SO, fractionation, Sephadex-G 200 column chromatography and DEAE Sephadex A-50 column chromatography. Filter paper-disintegrating, CMC-saccharifying and β-glucosidase activity were purified 10-fold, 47-fold and 38-fold, respectively. The crude enzyme was proved to be a complex of three different enzyme proteins which were showing filter paper-disintegrating, CMC-saccharifying and β-glucosidase activity. The optimal pH of the three enzyme components was alike pH 4.0, and the optimal temperature for CMC-saccharifying, filter paper-disintegrating and β-glucosidase activity were 40℃, 45℃ and 50℃ respectively. The Km and Vmax values of CMC saccharifying activity for CMC were 0.485% and 3.10(μmole/min·㎖), and the Km and Vmax values of β-glucosidase for ONPG(o-nitrophenol glucopyranoside) were 0.944×10 exp (-3)M and 0.097(μmole/min·㎖), respectively. The Km and Vmax values of filter paper-disintegrating activity for Avicel were determined to be 0.09% and 0.178(μmole/min·㎖), respectively. β-Glucosidase activity was competitively inhibited by glucose, and the Ki value for this enzyme was 3.54×10 exp (-3)M, CMC saccharifying activity was found to be greatly inhibited by cellobiose.

Koryoˇ(918-1392) made a certain progress in her culture and agriculture except the latter part of the era when the development in social economy were retarded due to military dictatorship and Mongol invasion. Despite of these external conditions, cultivations and kinds of horticulture foods were expanded with the help of many king`s agriculture first policy and the advancement in cultivating method. Among the horticulture foods, fruits such as peach, plum, Japanese apricot, apricot, cherry, pear, persimmon, pomegranate, crab apple, jujube, grape, Chinese quince, walnut, orange, yuzu, chestnut, ginkgo nut(silvernut), pine nut, nutmeg nut, and jat were growed, and vegetables such as Chinese cabbage, turnip, radish, garlic, welsh onion, gynmigit, scallion, taro, malva, cucumber, white gourd, bottle gourd, water melon, eggplant, Japanese ginger, ginger and litchi were cultivated, while seri, water shieled and bamboo sprouts were taken in natural. Fruits were taken in natural or through dry, and particularly grapes were used to make wine. Flowers of Japanese apricots, some fruit trees, and chrysanthemum were also made into wine. Certain fruits were used as medicine owing to its medicinal nature. Vegetables were used to make kimchi or to boil soup, sometimes they were dried to be kept in storage to be used in rare season and also used as medicine. Increase in kinds of horticulture foods does not have any direct relation with the reform of social economy, but the fact that so many kinds of horticulture foods were cultivated and used in Koryoˇ era shows that they elevated people`s life and dietary culture.
