中文摘要:
      为促进油茶籽副产物的高值化利用,采用低共熔溶剂提取油茶籽壳中的原花青素,通过单因素试验考察了提取溶剂种类、摄取溶剂质量分数、料液比、提取温度和提取时间对原花青素得率的影响,并利用正交试验对油茶籽壳中原花青素提取的工艺条件进行优化。结果表明:低共熔溶剂提取油茶籽壳中原花青素的最优工艺条件为以氯化胆碱-柠檬酸(物质的量比1∶1)溶液为提取溶剂、氯化胆碱-柠檬酸溶液质量分数80%、料液比1∶25、提取温度80℃、提取时间40 min,在此条件下原花青素得率为5.26%。综上,低共熔溶剂可有效提取油茶籽壳中的原花青素。
英文摘要:
      To promote the high value utilization of by-products from oil-tea camellia seed, procyanidins was extracted from oil-tea camellia seed shell with deep eutectic solvents,the effects of extraction solvent type, mass fraction of solvent, solid-liquid ratio, extraction temperature and extraction time on the yield of procyanidins were investigated by single factor experiment and process conditions for extraction of procyanidins from oil-tea camellia seed shell were optimized by orthogonal experiment. The results showed that the optimal extraction conditions were obtained as follows: with choline chloride-citric acid (molar ratio 1∶1) solution as extraction solvent, mass fraction of choline chloride-citric acid solution 80%, solid-liquid ratio 1∶25, extraction temperature 80℃, extraction time 40 min. Under these conditions, the yield of procyanidins was 5.26%.In conclusion, the procyanidins can be effectively extracted from oil-tea camellia seed shell with deep eutectic solvents.
