Abstract

Lycopene Z-isomerization and degradation in a series of hydrophobic natural deep eutectic solvents (HNDES) was firstly studied. The highest lycopene retention (about 84.6%) was found in HNDES composed of thymol and menthol (TM), and fatty acid-based HNDES promoted lycopene Z-isomerization (about 70% for total Z-isomers) and degradation. The addition of allyl isothiocyanate (AITC), diallyl disulfide (DADS) and capric acid into TM promoted Z-isomerization of lycopene (80% for total Z-isomers), especially 5Z-isomer (>30%), while lycopene remaining rate in TM/-capric acid was below 20%. During lycopene extraction from tomato power and watermelon juice by TM, the ratios of Z-isomer significantly (p < 0.05) increased especially with AITC and DADS (up to about 80%), and extraction yields increased even > 100% with capric acid. Lycopene in TM/-capric acid extracts showed low degradation with Z-isomers increasing during storage. TM with capric acid could simultaneously promote lycopene Z-isomerization and extraction.

摘要

本文首次研究了一系列疏水性天然深共熔溶剂（HNDES）中番茄红素的 Z-异构体异构化和降解。在由百里香酚和薄荷脑（TM）组成的 HNDES 中，番茄红素保留率最高（约 84.6%），而基于脂肪酸的 HNDES 则促进了番茄红素 Z-异构体异构化（总 Z-异构体约 70%）和降解。向 TM 中添加丙烯基异硫氰酸酯（AITC）、二烯丙基二硫化物（DADS）和癸酸可促进番茄红素 Z-异构体异构化（总 Z-异构体 80%，特别是 5Z-异构体（>30%）），而 TM/癸酸中的番茄红素残留率低于 20%。在通过 TM 从番茄粉和西瓜汁中提取番茄红素的过程中，Z-异构体的比例显著增加（p<0.05），尤其是添加 AITC 和 DADS 时（高达约 80%），并且添加癸酸甚至会使提取率增加>100%。TM/癸酸提取物中的番茄红素在储存过程中 Z-异构体增加，降解程度较低。含癸酸的 TM 可同时促进番茄红素 Z-异构体异构化和提取。
