| 为高效提取大蒜素,选用大蒜为原料,乙醇溶液为提取液,采用超声辅助渗漉法进行提取试验。考察了乙醇体积分数、超声时间、乙醇用量三个因素对大蒜素提取率的影响。选用响应面法,基于单因素试验探究的结果,优化大蒜素的提取工艺条件。结果表明:10 g蒜泥在40 ℃超声酶解30 min后,加入20 mL体积分数为65%的乙醇超声55 min,经165 mL体积分数为65%的乙醇溶液渗漉提取,大蒜素提取效果最佳,得率为0.439 mg/g。 |

| In order to efficiently extract allicin, garlic was used as the raw material and ethanol solution as the extraction solution. Ultrasound assisted infiltration method was used for extraction experiments. The effects of ethanol volume fraction, ultrasound time, and ethanol dosage on the extraction rate of allicin were investigated. Response surface methodology was used to optimize the extraction process conditions of allicin based on the results of single factor experiments. The results showed that after 10 g of garlic puree was enzymatically hydrolyzed at 40 ℃ for 30 minutes, 20 mL of 65% ethanol was added for 55 minutes, and 165 mL of 65% ethanol solution was leached for extraction. The best extraction effect of allicin was achieved, with a yield of 0.439 mg/g. |
