TITLE:
摘要: 目的:优化大蒜油的提取工艺。方法:以大蒜油提取率为指标,在单因素试验基础上采用 Box-Behnken响应面法对水蒸气蒸馏法提取大蒜中大蒜油的发酵时间、料液比、发酵温度等条件进行优化研究,对优化工艺进行验证试验。结果:最优提取工艺为发酵时间4.5 h、料液比1 ∶ 7、发酵温度55 ℃。验证试验中大蒜油平均提取率为0.32%(RSD=1.43%,n=3),实测值与预测值之间的相对误差为0.06%。结论:采用Box-Behnken响应面法优化所得大蒜油提取工艺简便、合理、可行,可为大蒜油工业化大生产提供参考。
ABSTRACT: OBJECTIVE: To optimize the extraction technology of garlic oil. METHODS: Using extraction rate of garlic oil as index, based on single factor test, Box-Behnken response surface method was used to optimize conditions of steam distillation method for the extraction of garlic as fermentation time, solid to liquid ratio, fermentation temperature and the verification test were made for the optimized technology. RESULTS: The optimal extraction technology was as follows as fermentation time of 4.5 h, solid to liquid ratio of 1 ∶ 7, fermentation temperature of 55 ℃. The average extraction rate of garlic oil in verification test was 0.32% (RSD=1.43%,n=3); the relative error between the measured value and predicted value was 0.06%. CONCLUSIONS: Box-Behnken response surface method is simple, reasonable and feasible to optimize the extraction technology of garlic oil, which can provide a scientific basis for industrial production.
