Evaluation of the Quality and Safety of Different Sources of Stareas

doi:10.7668/hbnxb.2011.S1.059

Abstract

Abstract: Collecting 22 different stareas from 8 different sources throughout the country,detecting the general indicators,starch content and gelatinization degree of starch,and then studying on the slow-release of starea in vitro,detecting the melamine and cyanuric acid in starea.The results showed that:the general indexes,starch content,gelatinization degree of the stareas from different sources in China were widely varying.We can assess the quality of starea by the release of NH3-N in 30 minutes in vitro.There were no melamin in stareas,the content of cyanuric acid which may be related with the content of cyanuric acid in urea was higher.Thus,the quality of the starea in China is a mixed bag,some of the products can not be slow releasing,we need to build the quality evaluation system for starea and regulate the market of starea.There were no risk of melamine in use of starea,but we should pay more attention to the content of cyanuric acid in starea.

Key words: Starea, Quality, Safety
