Practical use of wheat flour ferment with L. acidophilus during noodlemanufacturing was investigated. Water absorption decreased and overall mechanical tolerance index increased with ferment addition up to 20%. Amylograph of flour with ferment showed initial gelatinization temperatures of control, and 5% ferment-and ferment-added groups were equal. Maximum viscosity decreased by ferment addition. L, b and a values of dough increased proportionally with added ferment. Color of doughs with ferment was generally ligher. Total color difference of doughs added with ferment was higher than that of control group.

술떡으로 잘 알려진 증편은 막걸리 등의 술을 넣어 발효시켜 부풀려서 찐 떡으로 시큼한 술맛과 새콤하고 달착지근한 맛, 해면상의 조직 특징을 가진 여름떡이다. 전통적으로 증편의 발효원으로 막걸리 등의 술, 누룩, 엿기름 등을 사용하였는데 이때 발효시간이 8~12시간으로 긴 단점이 있다. 따라서 본 연구에서는 발효원으로 막걸리와 dry yeast를 사용하여 전통적인 증편의 시큼한 술맛은 유지하면서 발효시간을 단축시키기 위해 dry yeast의 첨가량을 멥쌀가루의 0.75%, 1.00%, 1.25%, 1.50%, 1.75%로 달리하여 증편의 부푸는 정도, 기계적 특성 및 관능적 특성을 저장기간 동안의 평가하였다.(중략)

관능성과 기능성이 증진된 김치를 제조하기 위해 polyphenol 성분의 함량이 높은 녹차를 부재료로 첨가하는 방법에 따른 김치의 발효특성을 조사하였다. 김치의 발효특성을 비교 조사하기 위하여 1%의 녹차 물추출물를 함유하는 소금물로 절인 후 담근 김치(I), 절임배추를 1% 녹차 물추출물에 일정시간 침지 후 제조한 김치(II), 녹차 물추출물 1%를 양념과 혼합하여 담근 김치(III)의 3가지 방법으로 김치를 제조한 후 1$0^{\circ}C$에서 숙성시키면서 pH, 산도, 균수, 총 페놀함량 및 관능적 품질을 조사하였다. 대조구의 pH는 숙성중 I~III의 경우보다 낮았고, 산도의 경우도 pH와 역으로 pH의 결과와 일치하였다. 그러나 녹차처리방법에 따른 큰 차이는 보이지 않았다. 대조구의 총균수와 젖산균수는 각각 6.27~9.22 및 4.50~8.28 log cfu/mL로 I~III의 5.46~8.47 및 4.55~8.00 log cfu/mL보다 높았다. 총 폴리페놀 함량은 김치의 적숙기에 높게 나타났으며 control

Soybean protein isolate was fermented using lactic acid bacteria. The properties of the lactic fermented soybean protein (LFSP) was compared with those of the lactic fermented rice (LFR). The LFSP was superior in nutritive value and rheological properties, whereas the LFR in color, flavor and taste. Mixing of the LFR and the LFSP was attempted to utilize the merits of both the LFR and the LFSP. The mixture was named Risogurt. The Risogurt had better flavor, taste, color and overall eating quality than the LFSP, and better nutritive value and consistency than the LFR. The optimum mixing ratio for the production of the Risogurt was 75% LFR and 25% LFSP.

In this study, the optimal fermenting conditions of sugar extracts of Artemisia annua L. (Aa), Houttuynia cordata Thunb (Hc), and Saururus chinensis Baill (Sc) were determined to develop fermented beverages. The sugar extracts ($50{\pm}5^{\circ}Bx$) were diluted to 10, 15, and $20^{\circ}Bx$, and fermented with 2% (v/v) of Lactobacillus plantarum DK119 ($5{\times}10^9CFU/mL$) at $37^{\circ}C$ for 4 days. According to the lactic acid bacteria population, pH, titratable acidity, and reducing sugar content, $20^{\circ}Bx$ for Aa, $10^{\circ}Bx$ for Hc and $15^{\circ}Bx$ for Sc were the maximum concentrations for the fermentation. There were no changes in total polyphenol content in the extracts of Aa, Hc, and Sc, whereas the radical scavenging activity and ferric reducing antioxidant power were increased during the fermentation. Lactic acid fermentation resulted in improvement of sensory evaluation scores on unfavorable plant taste and overall acceptability of the sugar extracts of medicinal plants.

This study developed a fermented chestnut puree by lactic acid bacteria fermentation using steamed chestnut paste at 95℃ for 90 min and the quality characteristics were investigated. In addition, quality of the characteristics of the fermented chestnut puree during fermentation by lactic acid bacteria were reported. 12 strains of lactic acid bacteria were inoculated to steamed chestnut paste at a concentration of 2%(v/w), respectively, and incubated at 37℃ for 48 hr. Lactobacillus plantarum(KCTC 21004) was the most superior in acid production among 12 strains of lactic acid bacteria to the fermented chestnut puree. The effect of steamed chestnut concentration, inoculum size and fermentation temperature for fermented chestnut puree on physical properties and fermentation characteristics were investigated. As a result there was no significant difference on physiochemical properties but the optimum concentration of the steamed chestnut for puree properties is 50%.

시루에 찌는 찐떡의 일종인 증편(蒸片)은 막걸리 등의 술, 누룩, 엿기름 등을 넣어 발효시켜 빵과 유사한 해면상(海綿狀)의 조직 특성을 갖는데 발효시간이 8-12시간으로 긴 것이 단점이다. 따라서 발효원으로 막걸리와 생이스트를 사용하여 전통적인 증편의 시큼한 술맛은 유지하면서 발효시간을 단축시키기 위해 생이스트 첨가량을 멥쌀가루의 0％, 0.25％, 0.50％, 0.75％, 1.00％로 달리하여 증편의 기계적, 관능적 품질특성을 저장기간 동안 평가하여 적합한 표준조리법을 제시하고자 한다. (중략)

붉은색의 완숙토마토에는 라이코펜이 함유되어 있고, 라이코펜은 베타카로틴 보다 암세포의 성장억제 효과가 10배나 강하다고 한다. 완숙토마토가 배추김치의 맛과 발효숙성에 미치는 영향을 알아보기 위해 배추김치에 대한 완숙토마토의 첨가량을 0, 10, 20, 30%(w/w)로 하였고, 1$0^{\circ}C$에서 28일 동안 발효시키면서 이화학적 특성을 보았다. pH는 모든 처리구에서 발효초기에 약간 높아졌다가 낮아지는 경향을 보였고, 발효 7일에서 발효 17일 사이에 처리구 0%의 pH가 가장 낮았다. (중략)

Strawberries fermented with Acetobacter pasteurianus SRCM60009 were prepared, and the quality characteristics and physiological activity were measured. As the fermentation period increased, viable cell counts increased, pH decreased, and total acidity increased from 1.09% to 4.20%. The organic acid content of strawberry through acetic acid fermentation was confirmed in the following order: acetic acid, succinic acid, citric acid, and lactic acid. Measurement of α-glucosidase and pancreatic lipase inhibitory activities and angiotensin converting enzyme inhibitory activity showed significantly increased physiological activity owing to fermentation. The use of strawberry vinegar as a functional material was confirmed by measuring the anti-diabetic, anti-obesity, and anti-hypertensive physiological activities through acetic acid fermentation of strawberry. Thus, fermented strawberry vinegar can be used as a functional material in vinegar and other foods.
