- 摘要:
- 为开发利用马铃薯新品种桂彩薯1号花色苷及研究其储存条件,以桂彩薯1号和紫云1号为研究对象,采用两种不同花色苷提取液进行提取比较,T1:1.5 mol?L-1HCl∶95%乙醇=15∶85(体积比),pH1.0;T2:1% HCl甲醇溶液,pH1.0,并对T1提取的桂彩薯1号花色苷提取液进行3个环境条件处理,分别为室温(25~30 ℃)自然光,4 ℃低温自然光,4 ℃低温黑暗,在放置天数为2,5,7,15和75 d时进行花色苷含量测定,观察花色苷降解过程,对马铃薯块茎中花色苷的提取方法进行比较,并对其提取后的降解影响因子等进行分析研究。结果表明:不同提取方法差异显著,用盐酸甲醇(T2)作提取液提取出的花色苷含量显著高于盐酸乙醇(T1);温度和光照均能影响马铃薯花色苷的降解,但温度影响效应大于光照。
