Abstract

Bovine hepatic extract is recognized as possessing detoxifying activity against various liver diseases. In orderto develop a process for its mass production, various enzymatic hydrolysis conditions were tested, and bovine hepatic extracts were prepared. These extracts were then examined for composition, microorganism levels, and vitamin $B_{12}$ content. Among the enzymes tested, papain was selected based on yields for dry residue and amino nitrogen. The other enzymes tested included bromelain, ficin, pancreatin, and protease NP. The optimal hydrolysis conditions were established at 65$^{\circ}C$ for 24 hr, with an addition of 1%(w/w) papain to the beef liver. The prepared spray-dried bovine hepatic extract showed an 11% recovery yield on a raw beef liver basis, with 95% dry residue and 11.8% total nitrogen content. Microorganisms were not detected in the dried extract, and its vitamin $B_{12}$ content was 4.1 ${\mu}$g/g. In summary, the conditions established in this study could be applied for the high yield mass production of bovine hepatic extract.

소간추출물은 각종 간질환에 해독효과를 가진 것으로 알려져있다. 항독성 소간추출물의 대량생산 공정을 개발하고자 효소의 선발 및 가수분해의 최적조건을 탐색하였고, 확립된 분해조건으로 항독성 소간추출물의 시제품을 제조하여 일반성분, 미생물, 그리고 비타민 $B_{12}$함량을 분석하였다. Bromelain, papain, ficin, pancreatin, 그리고 protease NP등의 효소 중 추출물의 건물량과아미노태 질소의 수율이 양호하고 경제성이 뛰어난 papain을 최적효소로 선발하였다. Papain(1%)을 소간 분쇄물에 첨가하여 65$^{\circ}C$에서 24시간 동안 가수분해하는 조건을 확립하였다. 분무건조한 항독성 소간추출물의 시제품은 원료 간 대비 11%의 수율을 보였고 건물량은 95%, 총질소 함량은 11.8%이었다. 또한 병원성 미생물은 검출되지 않았고 비타민 $B_{12}$ 함량은 4.1 ${\mu}$g/g이었다. 본 연구에서 확립한 가수분해조건은 높은 수율의 항독성 소간추출물 생산에 적용할 수 있을 것으로 생각한다.
