天然甘蓝食用色素化学稳定性研究

Research on Chemical Stability about Natural Cabbage Pigment

蔬菜花色素是天然食用色素中的一个主要类别,属水溶性色素。甘蓝色素是蔬菜花色素中新近开发的一种。本文测定了甘蓝色素吸收光谱和其在溶液中呈现红紫色的适宜酸度条件,观察了不同pH对该色素的影响和这些添加剂存在下它的光照稳定性。为甘蓝色素的开发应用提供了依据。

Vegetable pigments that can dissolve in water are major types of all natural edible pigment. Cabbage pigment is one of the newly developped vegetable pigments. This thesis measures absorbent spectrum of cabbage pigment and the suitable condition on which it appears purple. The thesis also observes that different pH influence the pigment and that these additions have an influence on its stability in the daylight. The thesis provides some bases for development and application of cabbage pigment.
