摘要:

对鸭血糯色素的稳定性进行研究。研究表明,鸭血糯色素在酸性条件下稳定性较好,而在碱性条件下稳定性极差,并且颜色发生改变;鸭血糯色素的热稳定性、光稳定性较好;糖类、食盐、柠檬酸、淀粉、山梨酸钾和苯甲酸钠对鸭血糯色素的影响很小;金属离子Mn2+、Na+、K+、Zn2+、Cu2+、Ca2+ 和Mg2+ 对鸭血糯色素的稳定性影响较小,Fe3+ 对鸭血糯色素的稳定性影响较大。

Abstract:

Stability of pigment from black sticky rice was studied. Results indicated that the pigment exhibited a good stability in acidic media, while its stability was weak in alkaline media. The pigment exhibited excellent thermal and light stability. Little effect of sugars, salts, citric acid, starch, potassium sorbate, sodium benzoate and metal ions including Mn2+, Na+, K+, Zn2+, Cu2+, Ca2+ and Mg2+ on pigment stability was observed. However, Fe3+ had an obvious adverse effect on the stability of black sticky rice pigment.

Key words: black sticky rice, pigment, stability
