摘要: 采用高效液相色谱法分析柑橘果皮类胡萝卜素在光照、高温、酸性环境以及氧化剂影响下的稳定性。光照、高温、酸性环境和氧化剂对柑橘果皮类胡萝卜素均有较强降解作用,主要是促使类胡萝卜素分子中C-C双键的氧化断裂。光照、高温和酸性环境能激发柑橘果皮类胡萝卜素不同方式的异构化。

Abstract: The stability of carotenoids in citrus peel was analysed with HPLC under the conditions of sunlight, high temperature, acid and oxidants. The carotenoids in citrus peel are easy degenerated by sunlight, high temperature, acid and oxidants. The main degradation mode is to oxidize and break the C=C double bonds of carotenoid. Different isomerization of carotenoids in citrus peel is elicited by sunlight, high temperature and acid.
