摘要
对番茄油树脂中的脂肪酸组成和类胡萝卜素进行了分析测定 ,并研究了番茄油树脂在贮存过程中番茄红素的稳定性 .结果表明 ,番茄油树脂中含有较多的脂肪酸甘油酯 (6 5 % )和不皂化物 (2 7% ) ,主要含不饱和脂肪酸 (74 %～ 75 % ) ,其中亚油酸质量分数为 5 1%～ 5 2 % ,油酸质量分数为 2 2 %～ 2 3% .番茄油树脂中类胡萝卜素主要是番茄红素 ,另外有少量的 β 胡萝卜素 .番茄油树脂贮存过程中番茄红素较为稳定 ,贮存条件以避光充氮效果最好 .
The components of tomato oleoresin were detected. The results showed that tomato oleoresin contained about 65% fatty acids as glycerides and 27% unsaponifiable matter. There were 74%～75% unsaturated fatty acids in which linoleic was about 51%～52% and oleic acid was 22%～23%. Studies on the stability of lycopene in tomato oleoresin showed that lycopene was stable during storage, and the best way was to keep with nitrogen in dark.
