无添加防腐剂的刺激性及其改善方法

Irritation of pseudo-preservatives and the methods for reducing irritation

通过鸡胚绒毛尿囊膜试验(HET-CAM)研究几款无添加防腐剂与传统防腐剂的刺激性强度,并寻找能够降低刺激性的方法。用HET-CAM方法对9种防腐剂的刺激性进行检测,通过刺激评分(IS)法对无添加防腐剂和传统防腐剂进行测评发现,部分无添加防腐剂和传统防腐剂均存在刺激性。针对有刺激性的防腐剂,进行了改善性探讨,最终发现多种舒缓原料可以降低绝大部分防腐剂刺激性。

The irritation intensities of several pseudo-preservatives and traditional preservatives were studied by Het-Cam Test, and a method for reducing irritation was found. The irritation of nine preservatives was tested by HET-CAM Test. By means of Irritation Score （IS）, it was found that some of the pseudo-preservatives and traditional preservatives both had irritation. For the irritating preservatives, the ways to ease stimulus was found, and the results showed that some soothing raw materials were effective for most irritating preservatives.
