摘要
以油茶籽为材料,利用响应面分析法优化油茶籽油水剂法提取工艺条件,并对得到油茶籽油的品质进行分析。结果表明最佳工艺条件为:原料经150℃烘烤后自然pH值条件下,提取温度80.2℃、水料比3.8:1(mL/g)、提取时间3.4h,在此条件下提油率可达69.1%。油茶籽油的各项理化指标均符合压榨二级油茶籽油国家标准,表明水剂法提取油茶籽油工艺是可行的。
Response surface methodology（RSM） was used to optimize the aqueous extraction of camellia seed oil.Quality characteristics of the resultant product were analyzed.The optimum conditions for the extraction of camellia seed oil were determined as follows： camellia seed kernels were dried at 150 ℃,crushed,and added with hot water at a solvent/solid ratio of 3.8：1（mL/g） for oil extraction at 80.2 ℃,natural pH for 3.4 h.Under these conditions,an oil yield of 69.1% was obtained.All tested physiochemical indexes of the oil obtained met the national standards for grade 2 camellia seed oil.Therefore,aqueous extraction is applicable for the extraction of camellia seed oil.
