Description
Technical field
The present invention relates to Oil processing technical fields, more particularly to a kind of animal oil extraction process low in calories.
Background technique
Animal oil, i.e. animal fat, are the fat of animal, are typically derived from pig, ox, fish for the animal oil that the mankind eat
Deng, can be used for processed food, enable food have meat fresh perfume (or spice).Oil biggish vegetarian diet, such as eggplant, radish etc., meeting are eaten in collocation
Have and make us the effect of appetite is opened greatly, promotes absorption of the human body to food materials nutrition especially vitamin.Animal oil taste is more fragrant, has
Promote the absorption of fat-soluble A, D, E, K etc..In addition, the weight of cholesterol or human tissue cell in animal oil
Ingredient is wanted, is the important source material for synthesizing bile and certain hormones.
The extracting method of animal oil has at present: squeezing method, cooking process, light alkali hydrolysis method, solvent method, enzymatic isolation method and overcritical
Fluids extraction etc..
What wherein application was wider is cooking process and light alkali hydrolysis method.Cooking process cannot separate the fat in conjunction with protein
It comes, therefore recovery rate is relatively low, and the temperature extracted affects the quality for extracting fat generally all at 90 °C or so.
Other nutritional ingredients further cannot be utilized efficiently after light alkali hydrolysis method mentions oil, cause very big waste.
Rule is squeezed firstly the need of high temperature drying, thus the animal oil produced is second-rate that (active lipid ingredient is impaired tight
Weight), and recovery rate is lower.Solvent method need to expend a large amount of organic solvent, and solvent easily remains in product.
Enzymatic isolation method is the hydrolysis using protease to protein, keeps the grease in conjunction with protein sufficiently free, but
The higher cost of enzyme.
Supercritical fluid extraction experiment scale of input is larger, fund is more, is relatively suitably applied the crude fish oil processing later period
The separating-purifying of physiological activator EPA and DHA, thus it is proposed that a kind of animal oil extraction process low in calories.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and the animal oil that the one kind proposed is low in calories
Extraction process.
A kind of animal oil extraction process low in calories, comprising the following steps:
S1: cleaning and crush, and cleans to fresh animal tallow, is crushed by crusher to animal tallow after cleaning,
Smashed animal tallow is in " jujube shape "；
S2: the pre-heat treatment will be added in process tank by S1 treated animal tallow, heat to animal tallow, heat
Temperature is 30-50 degree, is heated 30 to 50 minutes；
S3: electrolysis is fuel-displaced, and in by S2 treated animal tallow, conduction liquid is added, is powered to conduction liquid, current strength is
50-100A so that oil liquid is constantly precipitated；
S4: filter centrifugation separation, to by S3, treated that mixture is filtered, then to the animal oil of conduction liquid and precipitation
It is centrifuged, isolates animal oil therein.
Preferably, the conduction liquid is salt water, and brine strength is the sodium chloride solution of 2%-8%.
Preferably, it in the S3 step, when carrying out being electrolysed fuel-displaced, is constantly stirred, so that conduction liquid and tallow
Fat comes into full contact with.
Preferably, it in the S4 step, first passes through filter screen and the mixed liquor after S3 electrolysis is filtered, then pass through again
Conduction liquid and the animal oil of precipitation is centrifuged in centrifugal device.
Preferably, it after cleaning and crush animal fat in the S1 step, needs to take off smashed animal fat
Water.
Preferably, it when carrying out being electrolysed fuel-displaced to grease in the S3 step, is taken off when animal fat diameter is less than 1 centimetre
Oil finishes.
The invention proposes a kind of animal oil extraction processes low in calories, using the method for the electrolysis that is powered, so that animal oil
Animal oil in rouge is quickly precipitated, simple process, and preparation speed is fast, and preparation temperature is low, and grease impurities produced are few, oil colours
Good, condition is high.
