Safety assessment of enzymatically converted chicken bile as a novel food material: Genotoxicity, teratogenicity, and acute and subchronic toxicity studies.

Enzymatically converted chicken bile (CB), prepared by converting taurine deoxycholic acid (TCDCA) to taurine ursodeoxycholic acid (TUDCA) in CB, possesses various functional activities. But their nutrient composition and safety assessment have not been fully investigated yet. CB was mainly composed of proteins and steroids.

Enhancing enzymatic hydrolysis of xylan by adding sodium lignosulfonate and long-chain fatty alcohols.

Sodium lignosulfonate (SXSL) and long-chain fatty alcohols (LFAs) could enhance the enzymatic hydrolysis of xylan, and the compound of SXSL and LFAs have synergies on the enzymatic hydrolysis. SXSL shows a strong enhancement in buffer pH range from 4.0 to 6.
