摘要: 从预处理方法、浸提溶剂、料液比、浸提温度、浸提时间等方面对圣女果中番茄红素的提取工艺进行研究。经单因素试验对预处理方法及浸提溶剂进行选择,结果表明加入等体积无水乙醇、浸泡2h、离心脱水是提取番茄红素的最佳预处理方法,丙酮-正己烷(2:1)混合液是理想的提取溶剂。采用正交试验方法对液料比、提取温度和提取时间进行优化,得到适宜的提取条件为丙酮-正己烷(2:1)溶剂液料比为3:1、提取温度40℃、提取时间2.5h。在此提取工艺下,圣女果中的番茄红素提取量为4.08mg/100g。

Abstract: This study was carried out to optimize the extraction of lycopene from cherry tomatoes. Cherry tomatoes were pretreated before extraction. Soaking in the same volume of absolute ethanol for 2 h and centrifugation for water removal was found optimum for the pretreatment of cherry tomatoes. A mixture of acetone and n-hexane was found to be the solvent for lycopene extraction. The optimal conditions for lycopene extraction using the mixture were determined using an orthogonal array design to be extraction at 40 ℃ for 2.5 h with a solvent-to-solid ratio of 3:1 (mL/g). Under these conditions, the extraction yield of lycopene was 4.08 mg/ 100 g.
