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.
