摘要
对从葡萄皮渣中提取的葡萄皮色素稳定性进行研究。结果表明:酸度对色素稳定性影响较大,对色素有明显的增色效应;低温有利于色素的贮存;长时间日照会使色素逐渐降解;金属离子Fe3+对色素稳定性影响较大;添加剂H2O2对色素稳定性影响很大;维生素C水溶液、蔗糖水溶液、苯甲酸钠对色素稳定性影响较小。
The stability of pigment from grape peel was studied.The results showed that acidity was a factor which did more influence on its stability and an obvious effect in increasing the color was appeared,low temperature was beneficial to saving the pigment,long time sunshine would make pigment gradual to decline.Metal ions of Fe3＋and additives of H2O2did a more influence in the stability of pigment.Aqueous solution vitamin C,cane sugar aqueous solution,the sodium benzoates did a less influence in the stability of pigment.
