Example Embodiment

[0011] The method for preparing triglyceride fish oil provided by the present invention includes the following steps:

[0012] (A) Take raw materials ethyl ester 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 fish oil and glycerol into triglyceride fish oil using alkaline catalyst.

[0014] Furthermore, 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 to make the raw materials fully react, and the ethanol produced by the reaction is condensed and recovered , Then, the temperature of the reactor is cooled to 30℃~40℃;

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

Example Embodiment

[0027] Example one:

[0028] Take 100kg of ethyl ester fish oil, 10kg of glycerin, and 1kg of sodium hydroxide. At room temperature, turn on the water ring vacuum pump and stir the reaction kettle. The reaction kettle is evacuated by the water ring vacuum pump. The glycerin and sodium hydroxide are pumped into the reaction kettle, and the temperature is slowly raised to 155°C~165°C in the kettle, and the transesterification reaction is carried out. The reaction is kept constant for 1 hour to make the reaction fully complete. The ethanol produced during the transesterification reaction is recovered by the condenser. Then, the temperature of the reactant is reduced to 30°C-40°C with circulating cooling water. Then, 200L of purified water was added to the reaction kettle, stirred for 15 minutes, and allowed to stand still. After standing for 1 hour, the lower layer of water was removed and washed three more times in this way. After washing, the reaction kettle is evacuated with a ...

Example Embodiment

[0029] Embodiment two:

[0030] Take the raw material ethyl ester fish oil 150kg, glycerol 15kg, sodium hydroxide 1.5kg, at room temperature, turn on the water ring vacuum pump and the reaction kettle to stir, use the water ring vacuum pump to vacuum the reaction kettle, the vacuum reaction kettle, the ethyl fish oil , Glycerin and sodium hydroxide are pumped into the reaction kettle, the temperature is slowly raised to 155°C~165°C in the kettle, and the transesterification reaction is carried out, and the reaction is kept constant for 1 hour to make the reaction fully complete. The ethanol produced during the transesterification reaction is recovered by the condenser. Then, the temperature of the reactant is reduced to 30°C-40°C with circulating cooling water. Then, 300L of purified water was added to the reaction kettle, stirred for 15 minutes, and allowed to stand still. After standing for 1 hour, the lower layer of water was removed, and then washed 3 times in this way. Aft...

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...
