| 摘要: |
| 研究了大蒜素液真空酒精提取工艺、工艺参数（浸提真空度、时间、酒精浓度）对提取液中大蒜素含量、总硫化物含量的影响。结果表明：浸提液中，大蒜素含量与酒精浓度成负相关。总硫化物含量与酒精浓度和浸提真空度成正相关，大蒜素含量不随浸提真空度的变化而变化。通过正交试验优选出了大蒜素真空酒精提取较佳工艺参数（脱臭剂加入量15%，酒精浓度55%，浸提真空度7.7308×104Pa，浸提时间60d）。 |

| Processing for Vacuum Extraction of Allicin with Ethyl Alcohol |

| Abstract: |
| Allicin vacum extraction processing with alcohol was put forward in
this paper,the relationships between amounts of allicin and organic sulphur compounds
in extraction juice and processing parameters (concelltration of alcohol(%),degree of
vacuum(Pa))was studied.The restuts show that contents of allicin in extraction juice
in linear negative relation with contents of alcohol,and that of total contents of organic
sulphur compounds in extraction juice is in linear positive relation with degree of vacuum,but contents of allicin is not obviously changed.With the orthogonal experiment of
extractive processing,optimal parameters were obtained,such as: deodorization agent
15%,concentration of alcohol 55%,degree of vacuum 77.308 kPa,extractive time 60d. |
