preparation example Construction

[0011] A kind of preparation method of triglyceride type fish oil provided by the invention comprises the following steps:

[0012] (A) Take raw materials ethyl ester type fish oil, glycerin and alkaline catalyst, the weight ratio of the above raw materials is 100~150:10~15:1~1.5;

[0013] (B) Transesterification of ethyl ester type fish oil and glycerol into triglyceride type fish oil using basic catalyst.

[0014] Further, the above step (B) specifically includes the following steps:

[0015] (I) Put the raw materials in a vacuum reactor, the temperature of the reactor is 155℃~165℃, stir, the raw materials undergo transesterification reaction, the temperature in the reactor is maintained for a predetermined time, so that the raw materials can fully react, and the ethanol produced by the reaction is condensed and recovered , and then, the reactor is cooled to 30°C to 40°C;

[0016] (II) Add water to the reaction product in step (I) to wash, stir, and separate layers at rest...

Embodiment 1

[0028] Get raw material ethyl ester type fish oil 100kg, glycerin 10kg, sodium hydroxide 1kg, at normal temperature, open water ring vacuum pump and reactor stirring, water ring vacuum pump vacuumizes reactor, the reactor after vacuum, ethyl ester type fish oil, Pump glycerin and sodium hydroxide into the reaction kettle, slowly raise the temperature to 155°C to 165°C in the kettle, carry out the transesterification reaction, and react at constant temperature for 1 hour to make the reaction fully complete. The ethanol generated during the transesterification reaction is recovered by the condenser. Then, the temperature of the reactant is lowered to 30° C. to 40° C. with circulating cooling water. Then, add 200L of purified water to the reaction kettle, stir for 15 minutes and let it stand for 1 hour, then remove the water in the lower layer, and wash it 3 times in this way. After washing, the reactor is evacuated with a water ring vacuum pump to a vacuum degree of 0.085 MPa t...

Abstract

The invention relates to the field of preparation of fish oil and specifically relates to a preparation method of triglyceride type fish oil; and in addition, the invention further relates to the triglyceride type fish oil prepared by using the method. The preparation method of the triglyceride type fish oil comprises the following steps of: (A) taking raw materials of ethyl ester type fish oil, glycerin and an alkaline catalyst according to the weight ratio of (100-150): (10-15): (1-1.5); and (B) utilizing the alkaline catalyst to esterify the ethyl ester type fish oil and the glycerin to the triglyceride type fish oil. According to the preparation method of the triglyceride type fish oil, provided by the invention, the alkaline catalyst is used for transforming the ethyl ester type fish oil and the glycerin to the triglyceride type fish oil, so that the cost of the raw materials is low, the equipment investment is low, and the preparation method is easy to realize large-scale production. The triglyceride type fish oil produced by the method is further rich in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) which are omega-3 polyunsaturated fatty acids and ethanol-free and have no side effects after being taken.

Description

technical field [0001] The invention relates to the field of fish oil preparation, in particular to a method for preparing triglyceride-type fish oil; in addition, the invention also relates to a triglyceride-type fish oil prepared by the method. Background technique [0002] Fish oil is rich in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which has important physiological activities; whether it is used as a raw material for medicines or as a raw material for health food, it has broad development Application prospects. With the improvement of people's living standards and the continuous progress of science, the demand for fish oil products is also increasing. In the prior art, lipase is used to convert ethyl ester-type fish oil into triglyceride-type fish oil. This production process has high cost of raw materials and large investment in equipment, making it difficult to realize large-scale production. Contents of the invention [0003] The object of the p...
