摘要
研究了测定植酸酶降解植物性饲料中植酸磷程度的方法。该方法通过钒钼酸铵比色法测定植物性饲料水解液中磷的含量,进而求出其中植酸磷的水解度,并和重量法进行相关性比较,结果表明该方法是一种简便、快捷、准确度和精密度高的方法。
A method for determining the degradation of phosphor phytate degree in vegetable feeds by phytase was studied. The phosphor content in digest of vegetable feeds was determined by vanadium ammonium molybdate colorimetry, then the hydrolysis degree of phosphor phytate was determined and the relativity with gravimetric method was compared. The result showed that this was a simple, rapid, high- accurate and exact method.
