Abstract

The invention discloses an extracting method of garlic trithioether, which comprises the following steps: cleaning insoluble impurity in the garlic powder; pressing; adding pressed filtrate in the reacting stove; adding methyl ethyl ketone or acetone extractant as 1.2-1.8 times as filter pie weight to extract; pressing; removing filter slag; adding deodorant in the filtrate; evolving garlic odor as sediment; pumping liquid without garlic odor in the rectifying autoclave; removing initial fraction at 75-78 deg.c under 650 Pa; removing extractant at 80-82 deg.c under 660Pa; receiving the product at 85 deg.c under 680Pa.

Description

Technical field: [0001] The invention relates to a production method of garlic trisulfide. Background technique: [0002] The existing technology generally adopts CO 2 Supercritical technology extracts garlic trisulfide, which can only extract garlic oil, and there are many other components in garlic oil. The beneficial garlic trisulfide component can only reach about 20%, and the yield is only 1.07%. Invention content: [0003] The purpose of the present invention is to provide a method for extracting garlic trisulfide with high yield and high garlic trisulfide content in the finished product. [0004] Technical solution of the present invention is: [0005] A method for extracting garlic trisulfide, which is characterized in that it includes the following steps: washing garlic powder with water to remove impurities soluble in water, pressing for filtration, adding the filtrate from the pressure filtration into a reaction pot, and adding Extract with 1.2-1.8 times of m...
