摘要:

采用分子蒸馏技术,依据Box-Behnken 设计原理和响应面分析法,探讨分子蒸馏不同因素对分离、提取大蒜中大蒜精油的影响,选择最佳提取条件。结果表明:当控制系统的压力105Pa、进料速度1.2g/min、进料温度40~55℃范围内,蒸馏温度45.1℃时具有最好的二次分子蒸馏效果,大蒜精油的外观质量明显提高,平均总提取率可达0.476%,大蒜精油中水分为0.15%,纯度达99.85%。

Abstract:

Effects of different factors on extraction and separation efficiency of garlic oil were explored by using modern molecular distillation technology on the basis of Box-Behnken design principle and response surface analysis. The optimal extraction processing parameters were system pressure of 105 Pa, material-feeding rate of 1.2 g/min, material-feeding temperature of 40-55 ℃ and distillation temperature of 45.1 ℃. Under the optimal processing conditions, the quality of garlic oil was markedly improved, and the average yield of garlic oil was 0.476%. The content of water in garlic oil was 0.15% and the purity of garlic oil was up to 99.85%.

Key words: garlic, molecular distillation, extraction, garlic oil
