摘要:

以新疆吐鲁番赤霞珠葡萄籽为原料,采用超声波强化复合溶剂提取葡萄籽油工艺过程。通过试验确定了正己烷-石油醚(7:3,V/V)溶液为最佳溶剂。在正己烷-石油醚溶液为复合溶剂条件下,以超声温度、料液比、超声时间、超声功率等单因素试验为基础,采用响应面分析法(RSM)对超声波辅助混合溶剂提取葡萄籽油工艺进行优化,得到最佳工艺条件,即固液比1:12(g/mL)、时间35.5min、功率290W、温度51℃。在此条件下葡萄籽油提取率为19.19%,所得葡萄籽油的各项指标均优于溶剂法所得葡萄籽油。

Abstract:

Cabernet-Sauvignon grape seeds collected from Turpan in Xinjiang were used as the subjects to extract
grape seed oil through ultrasonic-assisted extraction. A mixture of hexane and petroleum ether at a ratio of 7:3 (V/V) was
considered as the best extraction solvent. Single factor tests were used to explore solid-liquid ratio, ultrasonic extraction
temperature, ultrasonic extraction power and ultrasonic extraction time. Response surface methodology (RSM) was applied
to optimize the extraction conditions. A maximum extraction rate of grape seed oil was achieved. The optimal extraction
conditions were solid-liquid ratio of 1:12 (g/mL), extraction duration of 35.5 min, ultrasonic power of 290 W, and extraction
temperature of 51 ℃. Under the optimal extraction conditions, the extraction rate of grape seed oil was up to 19.19%, and an
improvement in the measured physicochemical indexes was achieved compared with the grape seed oil from solvent extraction.
