【摘要】 以黑米为原料,采用超声波提取技术提取黑米黑色素,研究了水溶液中黑米黑色素在不同的pH值、光照、温度、还原剂、氧化剂、防腐剂和金属离子存在下的稳定性.结果表明,黑米黑色素在酸性环境下,在有Na⁺、Mg²⁺、Ca²⁺、Zn²⁺、Fe³⁺存在,和有还原剂、防腐剂和避光条件下,且温度低于60℃时,黑米黑色素的稳定性较好.更多还原

【Abstract】 In this paper,the stability of black rice melanin in the presence of different pH values,light,temperature,reducing agent,oxidant,preservative and metal ions was studied.The results showed that black rice melanin was at pH<6,in the presence of Na⁺,Mg²⁺,Ca²⁺,Zn²⁺,Fe³⁺,and a certain concentration of ascorbic acid,benzoic acid and dark conditions,and the temperature was lower than 60 ℃,the black melanin was stable,it can be used in the food and beverage industry.更多还原
