  • Addition of starch syrup, table sugar, potato powder, skim milk powder an parched soybean powder to melon flesh was suitable as fermented melon base. The manufacturing process of fermented melon was as follows: Pasteurization for 10 min at $95^{\circ}C$, use of 1% starter culture, fermentation for 12 hours at $35^{\circ}C$ and ripening for 3 days at $8^{\circ}C$. The growth and acid production of Pediococcus acidilactici among several starter cultures were most active for the first 12 hours, but such activities were disappeared during ripening. In the case of Lactobacillus plantarum, the activities were not high during fermentation, which, however, increased during ripening. Throughout the whole manufacturing process, the fermented melon with a mixed culture of P. acidilactici and L. plantarum showed more cell number of each bacterium and higher titratable acidity than that with single cultures. Also P. acidilactici surpressed the growth of L. plantarum during ripening.

  • 현재 유산균은 요구르트, 치즈, 케피어(kefir), 에시도필러스 밀크(acidophilus milk), 비피더스 밀크(bifidus milk), 쿠미스(kumiss), 발효버터(fermented butter), 유산균음료, 빵 등 식품의 천연 방부제, 채소절임, 발효두유(fermented soy milk), 정장제, 구강염증치료제, 사료 첨가제 등등 다양하게 이용되고 있다. 이것은 유산균에 대한 동결건조, 유전자 조작 등 첨단기술이 산업화로 연결되면서 그 이용성이 더욱 확장되고 있다. 유산균을 이용한 건강보조식품도 최근 몇년 사이에 선을 보이고 있지만 아직은 초보적인 단계이며 현재로선 유산균 발효식품과 유산균제제(의약품) 사이에서 뚜렷한 자기자리를 찾지 못하고 있는 실정이다.

  • This study was performed to evaluate the inhibition effects of fermented soybean on lipid perosidation and antioxidative relative enzyme activity. in vivo. Fermented soybean was induced the high SOD activity, while significantly inhibited on the peroxide value of linoleic acid and lipid perxidation from rat microsome induced by Fe$^{2+}$ ascorbate system, Sprague-Dawley(SD) male rats were fed basic diet, and experimental diets group added 200 or 500 mg/kg fermented soybean for 2 weeks. The effect of fermented soybean is also significantly increased catalase and glutathione peroxidase activities, while significantly inhibited the lipid peroxidation of rat liver microsome in a dose dependent manner. Therefore, these results suggest that fermented soybean has antioxidative activity which is related enzyme to prevention of oxidative stress.s.

  • This study aimed to develop high value-added mulberry (Morus alba) vinegar by fermenting mulberry with yeast and acetic acid bacteria, for using it in various foods. To select the optimal strain for mulberry fermentation, different strains were tested and Saccharomyces cerevisiae SRCM101756 and Acetobacter pasteurianus SRCM102419, exhibiting excellent alcohol and acetic acid production ability during mulberry fermentation, were selected for fermentation. Mulberry vinegar was prepared using mulberry wine and the selected acetic acid bacteria, and the physicochemical properties and physiological effects were measured. The pH was 2.98 and total acidity was 4.70% by day 9 of fermentation, establishing the possibility of developing them into vinegars for industrial use. The angiotensin-glucosidase inhibition activity of mulberry vinegar increased from 13.22% to 19.19% in the 100-fold dilution, and from 42.35% to 46.11% in the 50-fold dilution, from before fermentation to after fermentation, respectively. The angiotensin-converting enzyme inhibition activity of mulberry vinegar was found to significantly increase from 44.82% before fermentation to 63.88% after fermentation in the 25-fold dilution. Moreover, a significant increase in pancreatic lipase inhibition activity after fermentation was observed. Thus, mulberry vinegar can be used as a functional material in vinegar and other foods.
