摘要
为了在贮存和使用番茄红素的过程中保持其稳定性,采用有机溶剂法从成熟番茄果实中提取番茄红素,研究了理化因素对番茄红素的影响。结果表明:番茄红素对光,热,强酸,强氧化剂,Fe3+,Cu2+不稳定;而弱酸,弱碱,维生素C(Vc),苯甲酸,柠檬酸和K+,Mg2+,Zn2+等对其影响不大;常温(20℃)避光保存番茄红素,随时间延长也会发生部分降解。因此,应注意低温,避光,隔氧,并避免与强酸,Fe3+,Cu2+接触。
For the sake of keeping the stability of lycopene during storage and use,lycopene were extracted with organic solvent from ripe tomato fruits.Effects of physical and chemical factors on the lycopene were tested.The results showed that light,heat,strong acid,Fe3＋ and Cu2＋ destroyed lycopene,but the effects of weak acid and alkali,Vc,citric acid,benzoic acid,K＋,Zn2＋,Mg2＋ were not distinct.Lycopene reduced day by day under room temperature and with no light.So lycopene should be stored at low temperature with no light and oxygen,and avoid meeting strong acid,Fe3＋ and Cu2＋.
