Description
Technical field
The present embodiments relate to grease extractive technique more particularly to a kind of animal oil extracting methods.
Background technology
Animal fat is the grease obtained out of animal body.The grease of terrestrial warm-blooded animal and birds can be divided into, as butter,
Sheep oil, lard etc., usually solid, main component is palmitic acid, stearic triglyceride；The raw mammal in sea with
The grease of fish, such as whale oil, fish oil.Usually liquid, main component is except myristic acid, palmitic acid, stearic acid, oleic acid
Outside, also contain the unsaturated acids of 22~24 carbon and 4~6 double bonds and the unsaturated acids containing 10~14 carbon.Animal fat master
Want edible, such as lard, tallow, suet.Also it is widely used in manufacturing fixed oil, soap, glycerine, lubricating oil and leather industry
And drug；Fish oil is the raw material for preparing coating.It is obtained with decoction method.
Especially aquatic livestock oil is rich in abundant n-3 series polyunsaturated fatty acids, has very high nutritive value.Its
Middle eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) are not only to maintain one of the important component of cell activities,
And with different physiological roles such as prevention myocardial infarction, cardiac arrhythmia, reduction blood fat, atherosclerosis, anti-agings.In recent years
Come, the approval with people to aquatic livestock oil nutritive value, the utilization of aquatic livestock oil product become both domestic and external
Research hotspot, and it is widely used in the industries such as food, medicine, feed, chemical industry.Squid is a kind of larger water of China's amount of fishing
Product, full of nutrition, high protein, the low fat of squid are good processing of aquatic products raw materials.But it is former from some rich fat aquatic products
When extracting fat constituent in material or waste, protein etc. influences extraction process at branch.And effectively carrying about Squid Oil
Take the document that method is reported still considerably less.Reason is that Squid Oil is primarily present in internal organ, usually with albumen therein etc. at
Divide a kind of highly stable slurry material of formation mixed in together.
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 will be detached with the fat that protein combines
It comes, therefore recovery rate is relatively low, and the temperature extracted affects the quality of extraction fat generally all at 90 DEG C or so.
Other nutritional ingredients further cannot be utilized efficiently after light alkali hydrolysis method carries 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 relatively low.Solvent method need to expend a large amount of organic solvent, and solvent easily remains in product.
Enzymatic isolation method is the hydrolysis to protein using protease, keeps the grease combined with protein fully free, but
The cost of enzyme is higher.
Supercritical fluid extraction experiment scale of input is larger, fund is more, is relatively suitably applied the crude fish oil processing later stage
The separating-purifying of physiological activator EPA and DHA.
