Bifidobacteria are probiotic organisms that provide both flavor and health benefits when incorporated as live cultures into commercial dairy products. Because bifidobacteria are very sensitive to environmental conditions (acids, temperature, oxygen, bile salts, the presence of other cultures, etc.), their viability in human gastrointestinal tract is limited. The microencapsulation of bifidobacteria is a process to protect them against harsh environmental conditions, thereby increasing their viability while passing through human gastrointestinal tract. To confirm the survival rate of microencapsulated Bifidobacterium breve CBG-C2 in milk, their survival rate was compared with several kinds of free bifidobacteria and lactic acid bacteria in commercial yogurt products under simulated gastric and small intestinal conditions. Double-microencapsulation of the bacteria was employed to increase the survival rate during digestion. The outer layer was covered with starch and gelatin to endure gastric conditions, and the inner layer was composed of a hard oil for the upper small intestinal regions. Almost all microencapsulted bifidobacteria in the milk survived longer than the free bifidobacteria and lactic acid bacteria in the commericial yogurt products under the simulated gastric conditions. Numbers of surviving free bifidobacteria and lactic acid bacteria in the commercial products were significantly reduced, however, the viability of the microencapsulated bificobacteria in the milk remained quite stable under gastric and small intestine conditions over 3$\sim$6 hrs. Thus double-microencapsualtion of bifidobacteria in milk is a promising method for improving the survival of bifidobacteria during the digestive process.

국내에서 시판 유통되고 있는 9개$(A{\sim}I)$의 간장제품 중의 biogenic amine(BA) 함량을 조사하였다. 시판 간장에서 검출된 biogenic amine은 putrescine, cadaverine, tryptamine, ${\beta}-phenylethylamine$, spermine, histamine 및 tyramine으로 총 7종류가 검출되었으며, 각 제품에 따라 그 종류 및 함량 차이를 나타내었다. PUT은 6 제품에서 가장 높은 수준으로 검출되었으며, 가장 높은 제품과 낮은 제품에서의 함량차이가 약 16 mg/kg이상으로 나타났다. 6개의 제품에서 7종류의 BA이 모두 검출 된데 반해 한 제품(I)에서 5종류의 BA만이 검출되었다. I 제품은 putrescine을 제외한 모든 BA에서 유의적으로 가장 낮은 함량 수준을 보였으며, B 제품의 경우 7종류의 BA이 모두 검출되었고 함량도 유의적으로 가장 높게 나타났다. 따라서 간장의 화학적 유해요소에 대한 안전성 확보를 위해 지속적인 함량조사를 포함한 다양한 저감화 연구 등이 필요하다.

The objective of this study was to analyze bacteriological and chemical hazards in minimally processed commercial fish products, including Hwangtae (freeze-dried pollock), dried anchovy, fermented anchovy sauce, and salted and dried yellow croaker. Escherichia coli counts from all samples were below the regulation limits of the Korean Ministry of Food and Drug Safety Standards on Quality of Seafood and Seafood Products (Food Code). However, the food poisoning bacterium Staphylococcus aureus was detected at levels above $1.0{\times}10^2$ colony forming units (CFU)/g in Hwangtae, dried anchovy, and salted and dried yellow croaker, which are commonly ingested without heating and pose bacteriological hazards. The detection of S. aureus, an organism indicative of poor personal hygiene, which can be introduced by employees and multiply during distribution, indicates the necessity of improving the sanitary control of minimally processed commercial fish products. Histamine was not detected from dried anchovy or salted and dried yellow croaker, but was detected at some of the highest levels in fermented anchovy sauces. This result suggests that efforts to reduce the amount of histamine in fermented anchovy sauces are required.

It is very difficult to compare directly the research results of enzymatic process in pulp and paper industry because commercial enzymes have diversity in its property. The chemical and biological properties of commercial enzymes were Investigated to help comparison of various commercial enzymes each other. In most case, the solid content of liquid enzymes was about 20%. The higher protein content in enzyme product does not mean the higher enzyme activity. Enzymes for paper process should selected by basis of enzyme activity, not by price of enzyme products. The chemical composition of fiber was not so much change with enzyme treatment. The enzymatic hydrolysis of fiber might negligible in paper process.
