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

A kind of method of extracting fly maggot oil

Technical field:

The present invention relates to a kind of method of extracting fly maggot oil, is the production method of the fly maggot of industrialized aquaculture being carried out deep processing, belongs to the production method of food or drug additive, as the raw material of healthcare products.

Technical background:

Musca Insecta, Diptera, Aristocera, tame Nuscidae are a kind of that the most of area of China is the most common, quantity is maximum.Musca domestica larva as development object, the lipid content of its fly maggot dry powder is about 13%, and the unsaturated fatty acid content in the fat is a kind of good health care food raw material up to 60%, have good and wide application prospect, it is open still not have economically viable fly maggot oil extracting method at present.

Summary of the invention:

This purpose is to propose a kind of method of extracting fly maggot oil, promptly uses extraction, extracts the grease in the fly maggot to greatest extent, improves the housefly efficiency of resource.

The following technical scheme that the present invention adopts, promptly a kind of method of extracting fly maggot oil comprises the steps:

The first step, the processing of dried maggot powder the fly maggot of fresh cleaning, is used the mode of forced air drying and is dewatered under 60 ℃ of conditions, makes it moisture below 8%, pulverizes 20 mesh sieves, obtains dried maggot powder;

In second step, the sherwood oil lixiviate is inserted in the encloses container by sherwood oil and dried maggot powder weight ratio at 2: 1, soaks 24 hours under 25-30 ℃ of condition, leaves standstill and obtains solid-liquid two-phase mixed solution;

In the 3rd step, solid, liquid is separated, and uses 40 mesh sieves, vibrations are filtered, and the solid phase in the solid-liquid two-phase mixed solution in second step are separated, with filtrate airtight leaving standstill 48 hours in 25-30 ℃ of environment, when treating the supernatant liquid clarification, use siphon mode sucking-off supernatant liquid, obtain containing the ether fly maggot oil;

In the 4th step, underpressure distillation will contain the ether fly maggot oil at 35-45 ℃, underpressure distillation under-1 atmospheric pressure, and the cut that condensation is reclaimed is a sherwood oil, distillation back remaining component is a fly maggot oil.

Utilize the present invention can be met the fly maggot oil of health care demand.

Embodiment

The method of extraction fly maggot oil of the present invention is at first carried out the processing of dried maggot powder in the practice, the fly maggot of fresh cleaning, use the mode of forced air drying and dewater under 60 ℃ of conditions, makes it moisture below 8%, pulverizes 20 mesh sieves, obtains dried maggot powder; Then utilize the sherwood oil lixiviate, insert at 2: 1 in the encloses container, under 30 ℃ of conditions, soaked 24 hours, leave standstill and obtain solid-liquid two-phase mixed solution by sherwood oil and dried maggot powder weight ratio; Again solid, liquid is separated, uses 40 mesh sieves, vibrations are filtered, and the solid phase in the solid-liquid two-phase mixed solution is separated, and with filtrate airtight leaving standstill 48 hours in 30 ℃ of environment, when treating the supernatant liquid clarification, use siphon mode sucking-off supernatant liquid, obtain containing the ether fly maggot oil; Last underpressure distillation will contain the ether fly maggot oil at 45 ℃, underpressure distillation under-1 atmospheric pressure, and sherwood oil is reclaimed in condensation, and distillation back remaining component is a fly maggot oil.
