Description

A kind of animal fat and its extracting method
Technical field
The present invention relates to technical field of oil extraction, and in particular, it is related to a kind of animal fat and its extracting method.
Background technology
Animal fat has irreplaceable peat-reek compared with general vegetable fat, can promote the appetite of people.Greatly Measure and be used for food processing industry such as fried instant noodle, cake shortening, quick-frozen food, daily use chemicals industry soap, perfumed soap soap base raw material plus Work, glycerine extraction etc..Cholesterol level in discovered in recent years animal fat (particularly lard, sheep oil etc.) is higher so that food Crowd gradually decreases, but contains a variety of aliphatic acid in animal oil, and saturated fatty acid and insatiable hunger in some animal fats It is suitable with the content of aliphatic acid, there is higher nutritive value, and high heat can be provided, it is particularly suitable for cold district People eat.
Animal fat is essentially from animal slaughtering and cuts isolated adipose tissue, but most adipose tissue connects With protein and water, it is therefore desirable to carry out grease extraction.Animal fat extraction common method has：Decoction method, cooking process, solvent Method, enzymatic isolation method, supercritical fluid extraction and water soluble method etc..The evolution of animal fat extraction process is constantly to improve The recovery rate and DNA purity of grease, while caused impurity pollution on the environment in process is reduced as far as possible.
Patent document (the contrast text that existing data of publication of application is 2016.11.16, application publication number is CN106118871A Part 1) disclose the production technology that a kind of combined animal grease refines, data of publication of application 2017.01.04, application publication number The physical refining process and application public affairs of a kind of animal fat are disclosed for CN106281670A patent document (documents 2) The patent document (documents 3) that cloth day is 2017.01.04, application publication number is CN106281642A discloses a kind of animal The production technology of grease, documents 1 to 3 are to carry out the extraction of animal fat in confined conditions, are produced in refining process Oil smoke will not be discharged into air, so as to reduce the pollution to environment.But documents 1 need temperature be 120~ Melting is carried out under conditions of 180 DEG C, it is raw fragrant to carry out stewing system under conditions of being 130~180 DEG C in temperature；Documents 2 need Temperature carries out deacid-deodoring under conditions of being 250~255 DEG C；Documents 3 are needed under conditions of temperature is 180~220 DEG C Carry out melting.Patent document (the contrast text that existing authorized announcement date is 2015.01.14, Authorization Notice No. is CN103181421B Part 4) a kind of method for lifting animal oil flavor is disclosed, it is by the way that the enzymolysis product of animal adipose tissue and animal meat is mixed Close, boil and obtain the animal oil that flavor significantly increases under conditions of being 140~250 DEG C in temperature.But documents 1 It is the extraction of progress animal fat under the high temperature conditions to 4, this can cause animal fat sense of taste to deteriorate all the time, under nutritive value Drop, even results in the generation of noxious material, color physical property can also change.
Patent document (the contrast text that existing data of publication of application is 2015.05.13, application publication number is CN104611123A Part 5) disclose a kind of process for extracting of animal fat, although it is to be 80~110 DEG C in temperature under confined conditions to enter Capable oil plant extraction, temperature is relatively low, but the animal fat mouthfeel of its production is bad.
Therefore, the present invention provides a kind of method for extracting animal fat under cryogenic, and it can not only ensure animal Caused oil smoke is few in the extraction process of grease and generation without noxious material, and the animal fat extracted has uniformity, mouth Feel, the advantages of nutritive value is high and color and luster is good.
