番茄红素β-环糊精包合物的制备

Preparation of Inclusion Compound of (3 - Cyclodextrin with Lycopene

番茄红素是一类非常重要的类胡萝卜素,具有优越的生理功能。其分子中含有11个共轭及两个非共轭碳一碳双键,导致了它极不稳定,在光、热和氧的作用下很容易被氧化降解。近年来,环糊精包合技术在食品及医药中应用日益广泛,本文将此法用于番茄红素的包埋,实验结果表明,包合后可明显提高番茄红素的水溶性,改善它的稳定性。但由于主客分子比过大,包合物中番茄红素的含量偏低。

Lycopene is an important carotenoids. But the poor stability and solubility restricted its apply. The inclusion compound of β - cyclodextrin with lycopene was prepared. The result indicated that after inclusion the solubility and stability of Lycopene was improved. But the content of lycopene in the inclusion compound was very low.
