文中研究花色素苷功能饮料的稳定性。采用高效液相色谱法(HPLC)测定不同条件处理后饮料中的花色素苷的含量。花色素苷对温度和光照非常敏感,金属离子K+、Na+、Ca2+、Mg2+、Zn2+和Cu2+对花色素苷的稳定性没有显著影响。不同灭菌方式对花色素苷的稳定性影响不同,其中超高温瞬时灭菌法对其影响最小。结果表明:花色素苷功能饮料适宜在室温避光条件下保存,同时饮料中可适当加入一些金属元素增加其经济价值和营养价值;灭菌方式可采用超高温瞬时灭菌法,确保营养成分不流失。

Study on the stability of Anthocyanin energy drink.According to high performance liquid chromatography(HPLC) to determine the Anthocyanin content after different processing conditions.Anthocyanin is very sensitive to temperature and light,The stability of Anthocyanin is not significant effect to K~+,Ca~2+,Mg~2+,Zn~2+and Cu~2+,which is also different effects to different sterilization way,ultra high temperature short time sterilization as to it's affect the least.Anthocyanin energy drink can be conserved at room temperature for preventing light conditions,and can be appropriately added with some metal ions to increase its nutritional value;Ultra high temperature short time sterilization can be adopted to ensures that the nutrient composition is without loss.
