摘要: 目的:研究姜辣素的提取方法及其抗氧化性。方法:通过单因素和正交试验研究溶剂种类、乙醇体积分数、微波功率、微波处理时间、料液比因素对提取效果的影响,考察姜辣素在不同作用时间、不同温度下对油脂的抗氧化性能,并与一些天然抗氧化剂作比较。结果:当以66%乙醇为溶剂、料液比1:16(g/mL)、微波300W、微波协同处理70s作为提取姜辣素的最佳工艺条件时,姜辣素的提取率达到1.76%,该生姜提取物能增加植物油和动物油的抗氧化能力,在相同条件下生姜提取物对油脂的抗氧化效果强于柠檬酸而弱于鞣酸。结论:姜辣素可作为油脂中的抗氧化剂使用。

Abstract: The process for extracting gingerol with ethanol aqueous solution under microwave assistance was optimized by evaluating the effects of extraction solvent type, ethanol concentration in water, microwave power, microwave treatment time and material-to-liquid ratio on gingerol extraction using single factor and orthogonal array design methods. The optimum conditions for gingerol extraction were found to be: ethanol concentration, 66%; material-to-liquid ratio, 1:16; microwave treatment time, 70 s; and microwave output power, 300 W. The extraction yield of gingerol was 1.76% under such conditions. Meanwhile, the anti-lipid peroxidation activity of gingerol was assessed and compared with those of two natural antioxidants, and the results revealed that the extract from ginger was able to protect vegetable oils and lard against lipid peroxidation, and that its anti-lipid peroxidation activity was superior to citric acid but inferior to tannic acid.
