摘要
分别采用非极性树脂D101和弱极性树脂LSA-21对桑葚色素进行动态吸附处理,结果表明:经树脂D101处理后的色素色价较高;对其工艺学特性研究表明,在实验条件下,添加0.5%以下锌、钙盐色素稳定,Fe2+、Sn2+会引起色素变色;在30%以下木糖醇、低聚异麦芽糖介质中呈色稳定;异抗坏血酸钠、苯甲酸钠、山梨酸钾浓度超过0.03%后,呈色不同程度变浅,EDTA-Na对色素无影响。
The mulberry pigments were treated with non-polar resin D101 and weak polar resin LSA-21 respectively, the results showed that： the color value of the pigments treated with resin D101 was high. The study on its technical proprety showed that： at experiment conditions, calcium salt pigments was stable when adding under 0.5% zinc, and it would cause pigments change color after adding Fe2~, Sn2＊; The color was stable under 30% xylitol and isomaltose hypgather. Its color become different shallow when the concentration of sodium ascorbate, sodium benzoate and potassium sorbate was over 0.03%, but EDTA-Na has no influence to pigments.
