Abstract
The invention discloses a method for refining yellow mealworm oil, which comprises the following steps of: heating the obtained yellow mealworm crude oil at the temperature of between 60 and 80 DEG C with stirring, filtering, and degumming by adding water in an amount which is 3 to 5 percent of the weight of the yellow mealworm crude oil or 85 mass percent phosphoric acid in an amount which is 0.1 to 1 percent of the weight of the yellow mealworm crude oil; regulating the oil to the temperature of between 50 and 70 DEG C, and deacidifying by adding 20 mass percent NaOH solution in an amount which is 1.33 to 1.53 percent of the weight of the yellow mealworm crude oil; decoloring by adding activated carbon in an amount which is 4 to 6 percent of the weight of the yellow mealworm crude oil or clay in an amount which is 1 to 3 percent of the weight of the yellow mealworm crude oil; and deodorizing the decolored yellow mealworm crude oil at the temperature of between 150 and 160 DEG C in a vacuum state of 0.1MPa so as to prepare the refined yellow mealworm oil. The refined yellow mealworm oil is clarified and transparent, and light yellow, and has inherent aroma and taste of yellow mealworm oil and no peculiar smell; and the method is simple in process, low in equipment investment, continuous in production process and high in yield, and the product quality is easy to control.
Description
Technical field:
The present invention relates to a kind of insect grease, relate in particular to a kind of method of refining of tenebrio molitor grease.
Background technology:
The tenebrio molitor formal name used at school: Tenebrio molitor.Linne, another name: tenebrio molitor, big yellow nail are commonly called as the bread worm.Belong to Arthropoda, Insecta, Tenebrionidae, mealworm belongs to, and belongs to complete metamorphosis.Being a kind of large-scale storage pest and physiology, genetics test materials, is again the valuable source insect of great exploitation potential for its.Contain 8.6% fat in the tenebrio molitor, wherein nearly 90% lipid acid is C
16～C
18Lipid acid, wherein based on unsaturated fatty acids, oleic acid accounts for more than 50%, and linolic acid then reaches more than 25%.The ratio of its saturated fatty acid, monounsaturated fatty acids and polyunsaturated fatty acid extremely levels off to the edible best fatty acid ratio standard of human body that current trophology is recommended, and is a kind of good oil source.Tenebrio molitor is mainly used in edible protein and amino acid whose extraction at present, has developed food and foodstuff additive such as amino acid, amino acid worm wine, protein hydrolysate fermented nutritive liquid.But the development research of tenebrio oil also seldom, and the research of refinery practice still less.The exploitation of tenebrio oil is the important component part of tenebrio molitor comprehensive utilization of resources, all will play a positive role for improving tenebrio molitor economic worth and nutritive value.But tenebrio oil is a kind of insect oil, and wherein phospholipids content is higher, but also contains gelatinoid such as a large amount of shellac, makes that the crude oil color that extracts is dark, acid number is high, peculiar smell is heavy, so must pass through refining.Therefore, study its refinery practice and just seem especially important.
Summary of the invention:
Technical problem to be solved by this invention is: at above-mentioned the deficiencies in the prior art, on the technical foundation of vegetable oil and fat refining method, change processing condition, a kind of method of refining of tenebrio molitor grease is provided, make it meet the greasy characteristics of insect.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of method of refining of tenebrio molitor grease, this method comprises the steps:
A, pre-treatment: the tenebrio molitor crude oil that obtains under agitation is heated to 60～80 ℃, and filtered while hot is collected filtrate for later use; This tenebrio molitor crude oil can be through supercritical extraction, maybe can adopt milling process or obtain through solvent extraction method, and the method that this tenebrio molitor crude oil obtains is all prior art, does not repeat them here.
B, come unstuck: pretreated tenebrio molitor crude oil under agitation is heated to 60～80 ℃, is incorporated as the water of tenebrio molitor crude oil weight 3～5% then, continue to stir 30min, after 6～8h is left standstill in insulation, filter to isolate the phosphatide isocolloid; Or with 0.1～1% the mass concentration that adds crude oil weight in the pretreated tenebrio molitor crude oil 85% phosphoric acid, under 60-80 ℃, stir 20～30min with 60～70r/min, come unstuck finish after, with the centrifugal 10～15min of 4500～5000r/min, the upper strata oil sample is the tenebrio molitor crude oil that comes unstuck; During aquation, amount of water should be controlled, can not be too much or very few.Add water excess, easily cause grease emulsifying, and add to the difficulties for follow-up drying; It is very few to add water, and the colloidalmaterial precipitation not exclusively has precipitation in the oil, influence quality product.Because of the tenebrio oil phospholipids content higher, so hydration step is particularly important.
C, alkali lye depickling: the tenebrio molitor crude oil after coming unstuck, regulate the oil temperature to 50～70 ℃, when stirring, to the mass concentration that wherein is incorporated as tenebrio molitor crude oil weight 1.33～1.53% 20% NaOH solution, after continuing to stir 20～30min, place whizzer with the centrifugal 5～10min of the speed of 2000～3000r/min, isolate grease; Adding alkali number, concentration of lye, adding the alkali uniformity coefficient is the principal element that influences alkali refining, it is excessive to add alkali number, the oil soap increases, easily cause grease loss phenomenon: it is not enough to add alkali number, easily cause neat soap meticulous, precipitation a few hours oil soap does not still separate, and concentration of lye is rare excessively, excess moisture easily causes grease emulsifying; Add that alkali is inhomogeneous easily to cause local saponification excessive, the generation of the incomplete phenomenon of depickling.
D, decolouring: add the carclazyte account for the gac of tenebrio molitor crude oil weight 4～6% or to account for tenebrio molitor crude oil weight 1～3% in the tenebrio molitor crude oil after depickling and decolour, bleaching time is 15～25 minutes;
E, vacuum deodorization: the tenebrio molitor crude oil after will decolouring places under the vacuum state of 0.1MPa, distills 2～3h down at 150～160 ℃; After treating that deodorization is finished, tenebrio oil continues to close heating source under vacuum state, treat oily temperature drop to 40～60 ℃ after, close vacuum pump, tenebrio molitor polished fat.
The invention has the beneficial effects as follows that by the tenebrio molitor grease clear that above-mentioned processing step refining is produced, color and luster is yellowish, has tenebrio molitor grease inherent fragrance and flavour, free from extraneous odour.This Products Development is the important component part of tenebrio molitor comprehensive utilization of resources, has played positive effect for the economic worth and the nutritive value that improve tenebrio molitor, and for rationally efficiently utilizing insect resources that a good approach is provided.Method of refining technology of the present invention is simple, and facility investment is few, and production process is continuous, and output is big, and quality product is controlled easily.
