摘要

"animal feed ingredient, animal feed ingredient composition, and method of improving dietary starch digestion by monogastric animals" a protected Î ± -amylase is described. Pelletizing and encapsulating technology, where slow release materials and ph-sensitive materials are used to protect @ -amylase from low ph inactivation. Protected β-amylase is found to be highly stable after as much as 3 hours of acid treatment (ph3.0). When treated at pH 3.0 for 1 hour and followed by lipase and pancreatin treatment at pH 7.0 for 2 hours to simulate the in vivo environment, it was found that @ -amylase was fully released and measurable. In addition, protected β-amylase showed superior efficacy over unprotected β-amylase. Protected @ -amylase has also demonstrated enhanced thermostability.
