Problems solved by technology

[0002] At present, domestic crocodile oil is used as a raw material for cosmetics. There are two biggest problems in refining. One is the low extraction efficiency; the other is that it cannot retain more active ingredients such as unsaturated fatty acids;
Traditional crocodile oil is mainly prepared by high-temperature refining, which has low efficiency. The produced crocodile oil is dark yellow, has a very heavy crocodile smell, and has a rancid smell after oxidation. It has poor stability and is easy to oxidize. Many active ingredients are lost in the high temperature process, which is not acceptable to consumers, which limits the wide application of crocodile oil in skin care

Embodiment 1

[0023] (1) Pretreatment of crocodile oil adipose tissue: mix crocodile fat and water in a ratio of 1:1, chop and mix into a minced shape;

[0024] (2) Ultra-high pressure assisted enzymatic hydrolysis: the mixed solution is placed in an ultra-high pressure container, and crocodile oil is extracted by ultra-high pressure assisted enzymatic hydrolysis. The ultra-high pressure assisted enzymatic hydrolysis conditions are 200MPa, 60°C, 4h, and the selected enzyme is a compound enzyme ( Keratinase: lipase = 1:1), pressurize and inactivate the enzyme after the enzymolysis is completed, the condition is 500MPa, 25min, and separate the different phases of meat residue, oil and water from the enzymolysis solution to obtain the crude crocodile oil;

[0025] (3) Decolorization and deodorization: use a steam generator to pass steam into the crude oil for 30 minutes, the steam flow rate is 60m / s, and the rotation speed is 150r / min, condense and vacuumize to remove the fishy smell, and then ...

Embodiment 2

[0029] (1) Pretreatment of crocodile oil adipose tissue: mix crocodile fat and water in a ratio of 1:1, chop and mix into a minced shape;

[0030] (2) Ultra-high pressure assisted enzymolysis: the mixed solution is placed in an ultra-high pressure container, and the crocodile oil is extracted by the ultra-high pressure assisted enzymolysis method. The ultra-high pressure assisted enzymolysis condition is 250MPa, 55°C, 5h, and the selected enzyme is a compound enzyme ( Keratinase: lipase=1.5:1), pressurize and inactivate the enzyme after the end of enzymolysis, the condition is 450MPa, 30min, and separate the different phases of meat residue, oil and water from the enzymolysis solution to obtain the crude crocodile oil;

[0031] (3) Decolorization and deodorization: use a steam generator to pass steam into the crude oil for 30 minutes, the steam flow rate is 70m / s, and the rotation speed is 200r / min, condense and vacuumize to remove the fishy smell, and then separate oil and wat...

Embodiment 3

[0035] (1) Pretreatment of crocodile oil adipose tissue: mix crocodile fat and water in a ratio of 1:1, chop and mix into a minced shape;

[0036] (2) Ultra-high pressure assisted enzymatic hydrolysis: the mixed solution is placed in an ultra-high pressure container, and crocodile oil is extracted by ultra-high pressure assisted enzymatic hydrolysis. The ultra-high pressure assisted enzymatic hydrolysis conditions are 280MPa, 65°C, 4h, and the selected enzyme is a compound enzyme ( Keratinase: lipase = 2:1), pressurize and deactivate the enzyme after the enzymolysis is completed, the condition is 500MPa, 25min, and separate the different phases of meat residue, oil and water from the enzymolysis solution to obtain the crude crocodile oil;

[0037] (3) Decolorization and deodorization: use a steam generator to pass steam into the crude oil for 30 minutes, the steam flow rate is 50m / s, and the rotation speed is 120r / min, condense and vacuumize to remove the fishy smell, and then ...

Abstract

The invention discloses a method for extracting and refining crocodile oil. The method for extracting and refining crocodile oil disclosed by the invention comprises the following steps: (1) pretreating crocodile oil adipose tissue: mixing crocodile adipose with water in proportion, and performing chopping into paste; (2) performing ultrahigh-pressure assisted enzymolysis: putting the pasty crocodile adipose into an ultrahigh-pressure container, extracting crocodile oil by utilizing an ultrahigh-pressure assisted compound enzymolysis method, then performing pressure boosting and enzyme deactivation, and performing separation of different phases of meat residues, oil and water on enzymatic hydrolysate to obtain a crocodile oil crude product; (3) performing decolorization and deodorization:removing fishy smell of the crocodile oil crude product obtained in the step (2) by adopting a steam distillation method, performing oil-water separation to obtain crude oil, and then adding activatedcarbon and carclazyte into the crude oil for decolorization and deodorization; and (4) removing impurities and bacteria: removing foreign matters in the crude oil obtained in the step (3) and performing sterilizing to obtain essential oil. The method provided by the invention has high enzymolysis efficiency, retains more active ingredients and flavor substances, and effectively removes fishy smell.
