花青素

Has a brilliant red color and is a good source of anthocyanins. Roselle calyx possesses unique flavor, high acidity and low sugar. Extraction methods can be used to produce drinks.

为鲜艳红色，是良好花青素来源，果萼并具独特风味、酸度高和糖度低等特性，故利用萃取方式，制成饮品。

The results showed that there were five kinds of anthocyanin with possible acyl groups in the purple napiergrass.

结果显示，紫色狼尾草之花青素有五种成分，可能含有乙醯基，在pH 1-8之条件下，5 ℃贮藏三个月时以pH 1及2最为稳定，若在90 ℃加热12小时后，则在pH 2下稳定性最佳。

The recent research advances in natural pigments has been reviewed from following aspects: the advantage and disadvantage of natural pigments, stabilization technologies which include anti-oxidant added in pigment, molecular modification, anthocyanins acylate, etc.

对天然食用色素的优缺点和稳定化技术进行了详尽的描述，稳定化技术包括在天然色素中添加稳定剂和抗氧化剂，改造色素分子的结构，对花青素进行酰基化等。
