Abstract

The manufacturing process and quality properties of Lactococcus lactis-fermented yakchobugak (LFY) containing some colored agro-food products were investigated to develop a good organoleptic bugak from the leaf of the medicinal herb. The de-oiling rate of LFY by centrifugation was 37.6%, which was significantly different to the 3.5% value obtained after standing and the 8.9% value obtained with the beating method (p<0.05). Reducing power (RS) increased with addition of increasing levels of ethanol extracts from agro-food powders. The RS of green tea extract-supplemented LFY had the highest value of 0.97 at $500{\mu}g/mL$, and this was significantly different to values obtained using other extracts (p<0.05). At 83.84%, the DPPH (2,2-diphenyl-1-picrylhydrazyl) free-radical scavenging activity of green tea extract-supplemented LFY was the greatest of all samples tested, followed by LFY with woolgeom at 39.48%, LFY with black rice at 28.45%, and LFY with bokbunja at 22.24% all ethanol extracts were added at $50{\mu}g/mL$ (p<0.05). Acid values of green tea and bokbunja LFYs stored in transparent PE bags at $60^{\circ}C$ for 7 days were 1.82% and 2.03%, respectively. Textural hardness values of LFYs were less than 250.62, except for LFYs with black rice and woolgeom, but these values increased $2{\sim}3$-fold after lactic acid fermentation. Carbohydrate and protein content of LFYs were in the ranges $58.95{\sim}64.63%$ and $7.50{\sim}8.68%$, respectively. Lipid and calorie contents of woolgeom LFY had the lowest values of 22.02% and 490 Kcal, respectively.

기호성과 품질성이 우수한 전통부각을 개발하기 위하여 천연색소 함유 농산물과 유산균을 이용한 발효약초부각의 공정개발과 그 품질특성을 조사하였다. 약초부각의 탈유율은 정치 3.5%나 타봉 8.9%에 비하여 원심력이 약 37.6%로서 효과적이었다(p<0.05). 환원력은 부재료 추출물의 농도에 비례적으로 증가하였으며, 녹차는 다른 추출물에 비하여 유의적 차이가 크게 나타났으며, $500{\mu}g/mL$에서 0.97로 가장 높게 나타났다(p<0.05). DPPH 자유라디칼 소거능은 $50{\mu}g/mL$에서 녹차가 83.84%로 가장 높았으며, 다음으로 울금 39.48%, 흑미 28.45%와 복분자 22.25% 순이었다(p<0.05). 산가는 $60^{\circ}C$로 7일간 고온저장한 녹차와 복분자 발효약초부각이 각각 1.82, 2.03%였으며, 14일까지는 울금과 복분자 발효약초부각이 7.24, 7.67%로 효과적이었다(p<0.05). Hardness값은 흑미와 울금을 제외한 발효약초부각은 250.62 이하로 아주 낮았으며, 유산균발효 공정은 $2{\sim}3$배의 조직감 개선에 효과적이었다. 발효약초부각의 탄수화물과 단백질은 $56.8{\sim}64.6%$, $6.8{\sim}$8.7%이었고, 지방은 울금과 녹차 발효약초부각이 각각 22.1, 24.8%로 비교적 낮은 함량이었으며, 열량은 울금이 487 Kcal로 가장 낮았다.
