Description
Technical field
The present invention relates to the insects agro-processing technology, particularly from tenebrio molitor, extract greasy method.
Background technology
Tenebrio molitor has characteristics such as growth is fast, breeding coefficient height, and main food is agricultural waste material; Tenebrio molitor is rich in the multiple nutrients material, has very high exploitation to be worth, and has realized industrialized culture, and national annual production has reached tens0000 tons; The tenebrio molitor industrialization development is listed in Ministry of Agriculture's " Bumper Harvest Plan " by country, and prospect is very wide.At present, the application of tenebrio molitor is only for the bait of special cultivation animal, and comprehensive deep processing still belongs to blank, and the extraction of tenebrio oil and application yet are in the stage at the early-stage, and tenebrio oil is high-grade protective foods, also can make important chemical material.Extracting grease from the tenebrio molitor polypide, mainly is at present the method that adopts traditional squeezing and organic solvent to leach, and pollution is big, extraction yield is low, energy consumption is high, and oil quality is low, has a strong impact on the development and utilization of tenebrio molitor industry.
Summary of the invention
The extracting method that the purpose of this invention is to provide a kind of efficient height, less energy consumption, no solvent residue, the pollution-free and tenebrio oil that quality product is high.
The manufacture method of this tenebrio oil, feature are to carry out supercritical CO with the tenebrio molitor drying, after sieving
2Fluid extraction and extract separation circuit are handled.
The tenebrio molitor water content of drying is 6-10%; The dry tenebrio molitor granularity of sieving is the 14-30 order.
Supercritical CO
2Fluid extraction pressure is 20Mpa-40Mpa, and extraction temperature is 35-55 ℃, CO
2Fluid flow rate is 800-1200L/h, and the extraction time is 40-100 minute.
The present invention extracts the method for tenebrio oil, feature be earlier with the tenebrio molitor drying, sieve, then the tenebrio molitor fragment is put into extraction kettle, pump into CO
2Gas carries out supercritical CO
2Fluid extraction carries out the extract separation circuit subsequently and handles: isolates thick oil via the secondary separating still, obtain the tenebrio molitor grease through rectifying again.
Beneficial effect
The present invention adopts state-of-the-art in the world supercritical CO
2Abstraction technique extracts tenebrio oil, have efficient height, less energy consumption, no solvent residue, pollution-free, security good, the oil quality advantages of higher, to promoting the tenebrio molitor industrialization development, the promotion structural readjustment of rural industry, building a New Socialist Countryside have crucial meaning.
Measure by analysis, the tenebrio oil that extracts with the inventive method contains following composition:
C12:0 (lauric acid) 0.15-0.2%
C14:0 (myristic acid) 2.50-2.8%
C16:0 (palmitinic acid) 17.6-18.8%
C18:3 (linolenic acid) 2.6-2.89%
C18:0 (stearic acid) 2.1-2.95%
C18:1 (oleic acid) 38.4-39.3%
C18:2 (linolic acid) 33.6-34.7%
C20:0 (eicosanoic acid) 1.86-2.13%
C20:1 (arachidonic acid) 0.26-0.56%
According to analytical results as can be seen, in this grease, insatiable hunger is closed lipid acid and is accounted for about 75%, and its content exceeds 1 times of peanut oil, exceeds animal grease 2-3 doubly.The function that lipid acid has resisting oxidation free radical is closed in insatiable hunger, and business is worth very high; It should be noted that especially in the present invention and extract in the grease that needed by human and self can not synthetic linoleic acid contents higher (more than 33%), so the product tenebrio oil that the present invention extracts is high edible oil of nutritive value and healthcare products.
In addition, tenebrio oil viscosity and cloud point that this method is produced are lower, and heating experiment (280 ℃) oil colours shoals, no precipitate, and transparency improves.Free from extraneous odour has distinctive smell of grease and flavour.
Because the tenebrio oil that the present invention extracts has above-mentioned good composition and quality, can further develop this greasy new purposes: 1, cosmetic material: have moisture-keeping efficacy, strong with human body skin avidity, directly add in the makeup, effect is fine; 2, industrial raw material: produce alizarin assistant (a kind of technical oils) through making with vitriol oil generation sulfonation reaction; 3, industrial oil properties-correcting agent: have low temperature resistant, lubricated effect, can be used as the low-temperature lubrication oil additive, after refining, can be used as the properties-correcting agent of transformer and precision meter, instrument oil, add in these instrument oils and can strengthen its performance index, add in the lubricating oil and can strengthen the low-temperature lubrication performance.
