Embodiment Construction

[0010] The method for extracting fly maggot oil of the present invention, in practice, at first carry out the processing of dry maggot powder, apply the mode of blast drying to dehydrate the fresh and clean fly maggot under 60 ℃ condition, make its water content below 8%, pulverize 20-mesh sieve to obtain dry maggot powder; then use petroleum ether to extract, put it in a closed container according to the weight ratio of petroleum ether and dry maggot powder 2:1, soak at 30°C for 24 hours, and stand to obtain solid-liquid two-phase Mixed liquid; then separate the solid and liquid phases, use a 40-mesh sieve, vibrate and filter, separate the solid phase in the solid-liquid two-phase mixed liquid, seal the filtrate at 30°C for 48 hours, and wait for the upper liquid to be clarified , apply the siphon method to suck out the upper layer liquid, and obtain the ether-containing fly maggot oil; finally vacuum distillation, the ether-containing fly maggot oil is distilled under reduced...

Abstract

The invention relates to a fly-maggot fat extraction method. It is the deep-processing producing method for the fly-maggot. The content of the unsaturated fatty acid in the fly-maggot fat can reach 60%. The method includes the following steps: processing dry maggot powder; ligroin lixiviating; solid-liquid phase separation; siphoning; and vacuum distillation. And it can gain the fly-maggot fat which satisfies the health demand.

Description

Technical field: [0001] The invention relates to a method for extracting fly maggot oil, which is a production method for deep processing industrialized cultured fly maggots, belongs to the production method of food or medicine additives, and is used as a raw material for health care products. technical background: [0002] The houseflies belong to the class Insecta, Diptera, Cylindrica, and Muscaidae. They are the most common and the most numerous species in most parts of my country. As the housefly larvae of development object, the fat content of its fly maggot dry powder is about 13%, and the unsaturated fatty acid content in the fat is as high as 60%, is a kind of good health food raw material, has good and wide application prospect, still has No economically viable extraction method of fly maggot oil is disclosed. Invention content: [0003] The purpose of the present invention is to propose a method for extracting the oil of the fly maggot, that is, to extract the o...
