Cultural Conditions of Pleurotus ostreatus 201 for the Production of Cellulolytic Enzymes in Synthetic Medium
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 67~72
Cultural conditions and carbon sources affecting the productivity of cellulolytic enzymes of Pleurotus ostreatus 201 were examined in synthetic media. The optimum cultural temperature and initial pH for the production of enzymes were
and 5.5 in avicelase, and 3
and 5.0 In CMCase, and 3
and 6.5 in B-glucosidase. Among carbon sources, cellulose powder was the best for the production of avicelase, and Na-CMC for CMCase, and cellobiose for
-glucosidase. The optimum concentration of cellulose powder was 1.0% (w/v), and glucose depressed the production of enzymes remarkably.
Food Components of Coho Salmon and Rainbowtrout
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 73~80
In order to examine food components of coho salmon and rainbow-trout, We analyzed the composition of protein, amino acids and total lipids. The coho salmon muscle contained about 19.3% of protein with the composition of 29.9% in sarcoplasmic protein, 56.3oA in myofibrillar protein 12.5% alkali soluble protein and 2.6% in stroma. Those of rainbow-trout contained 34.1%, 56.4%, 8.3% and 2.9%, respectively. The sarcoplasmic and myofibrillar protein were composed of 13 subunits in coho salmon, and 16 and 15 subunits in rainbow-trout. Judging from the contents of essential amino acids, both muscle proteins were complete proteins. The most remarkable feature of free amino acids was that a large amount of dipeptide anserine was present with fairly lower levels of 1 methyl histidine, taurine, histidine, alanine and glycine in both muscle extracts. The total fatty acids of coho salmon was composed of 31.49% polyenes, 43.79% monoenes and 24.73% saturates. The composition of total fatty acid of coho salmon muscle was not different from that of rainbow-trout muscle.
A Study on the Infant Feeding Method of Mothers in Suwon City
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 81~88
This survey was conduced to investigate the feeding methods of mothers in Suwon, Kyungkido. Incidence of breast feeding was 29.9eA of the Interviewed mothers, which showed lower percentages than those of previous surveys. The jai or factors influencing the method of infant feeding were generally depended on mother rather than infant. The mothers who had a higher income and a higher academic career tended to pre(or the bottle feeding to the other. md first birth order made them select the breast feeding rather than the other. Generally mothers knew the information about infant nutrition very well (91.0%), but their knowledge actually did not work. The sources of mother's Information on the Infant nutrition were the books of rearing infants and magazine. But there were some discrepancies between the actual and needed source of information : i.e. mothers wanted to acquire their information from mass communication.
Conditions for the Production of Amylase and Protease in Making Wheat Flour Nuluk by Aspergillus oryzue L2
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 89~95
A Nuluk, a Korean traditional Koji for brewing, was made with wheat flour and Aspergillus oryzae L2 which had a good aroma and strong abilities In producing saccharogenic and dextrogenic enzymes. The cultural conditions for the production of saccharogenic and proteolytic enzymes were tested. The productivity of dextrogenic enzyme was improved when Nuluk was made with unsteamed wheat flour as compared with steamed one, but that of proteolytic enzyme was reduced. The addition of water containing 0.5% hydrochloric acid was unfavorable for the production of those two enzymes. The optimum ratio of water added to wheat flour for the production of those two enzymes was 28
on the basis of wheat flour, The productivity of saccharogenic enzyme was enhanced when the Nuluk was molded after 20 hours of precultivation, but that of proteolytic enzyme was reduced as compared with no molding. The optimum temperatures for the production of saccharogenic enzyme and proteolytic enzyme were 36
Conditions for the Production of Amylase and Protease in Making Wheat flour Nuluk by Rhizopus japonicas T2
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 96~102
A Nuluk, a Korean traditional koji for brewing, was made with wheat flour and Rhizopus japonicus T2 which had a good aroma and strong abilities in producing saccharogenic and proteolytic enzymes, and cultural conditions for the production of those two enzymes were tested. The productivity of saccharogenic enzyme was markedly improved when Nuluk was made with unsteamed wheat flour as compared with that with steamed one, but that of acid protease was reduced. The addition of water containing 0.5% hydrochloric acid was unfavorable for the production of saccharogenic enzyme and neutral protease. The optimum ratio of water added to wheat flour for the production of saccharogenic enzyme and proteolytic enzyme was 28% on the basis of wheat flour. The productivity of saccharogenic enzyme was enhanced "when the Nuluk was molded after 10~20 hours precultivation but that of proteolytic enzyme was reduced as compared with no molding. The optimum temperature for the production of saccharogenic enzyme was 28f and that of proteolyic enzyme was also 28
. The optimum cultural time for the production of saccharogenic enzyme was 36 ~72 hours at 3
and that of proteolytic enzyme was 36 hours.ours.
The Contents of Free Sugar and Alcohol in Traditional Soy Sauce Prepared from Meju under Different Formations
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 103~108
The Kinds of soy sauce were prepared using the brick type of conventional meju(A), the brick type of meju of Aspergillus oryzae(B), and the grain type of meju of Aspergillus oryzae(C). Free sugar and alcohol were analyzed in accordance to aging time of those products. Galactose, glucose, arabinose, xylose, and mannose were detected in all kinds of soy sauce. In soy sauce 4 galactose, glucose, arabinose, and xylose were shown in the order of content. The content of galactose in soy sauce A and soy sauce C were shown higher than that in soy sauce B alt during the time. The content of glucose was highest among that of all kinds of free sugars at the beginning of preparation, but the content of glucose was lower than that of arabinose and xylose after 60 days. The contents order of total free sugar was soy sauce C > soy sauce B > soy sauce A. The content of ethyl alcohol was shown 6.23∼19.10mg%, and that of isobutyl alcohol was 8.70∼ 169.03 ppm in all soy sauces, but those of soy sauce C was higher than those of other soy sauces.
Effect of Nepalese Pseudo Ginseng Components on Lipolytic Action of Toxohormone-L from Cancerous Ascites Fluid
The Korean Journal of Food And Nutrition, volume 6, issue 2, 1993, Pages 109~114
This study was divised to observe an Inhibitory effect toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG ; Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of Sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol Precipitate component of large root NPG (mean 55.5%) was higher (mean 1.37 times) than that of water extract component in final reaction concentration of 500 and 1, 000ug/ml, on the other side inhibitory effect of water extract component in small root NPG (mean 55.5%) was higer (mean 1.14 times) than that of ethanol precipitate component. In a way inhibitory effect of precipitate component In large root NPG(47.6%), when final reaction concentration of sample were 1, 000ug/ml, was about 40% lower than that of Korean red ginseng.
