摘  要:
研究了从山竹壳中所提取色素的稳定性。结果表明,山竹壳色素是一种醇溶性色素,耐日光及耐热性强;pH对色素有影响,在pH3~7范围内色素稳定;与常用食品添加剂葡萄糖、蔗糖、苯甲酸钠有好的混用性,但氯化钠及氧化剂和还原剂皆不利于色素稳定性的保持;金属离子K+、Na+、Ca2+、Mg2+、Zn2+对色素影响很小,Cu2+使色素颜色加深,Fe3+对色素有显著破坏。

摘  要:
The stability of pigment extracted from mangosteen was studied in this paper. The results showed that the pigment is soluble in alcohol and highly sunlight-resistant and heat-resistant. The pH value affects the stability of the pigment but it is stable in range of pH3~7. It lumps well as food additive in common use of glucose, sucrose, sodium benzoate, but NaCl and oxidizer and reducer can harm its stability. K+, Na+, Ca2+, Mg2+, Zn2+ hardly affect the color and stability of the pigment, but the color turns deep with Cu2+, while Fe3+ greatly damages the pigment.
