Embodiment 1

[0092] Take 400g of 95% ethanol in a water bath and heat it to 50°C, add 100g of urea to dissolve it under stirring, and flush it with nitrogen. Stir for 1 hour, cool down to room temperature naturally, stand for crystallization at 0-15°C, quickly filter with suction, concentrate the filtrate under reduced pressure at 50°C to recover ethanol, and wash the obtained concentrated solution with saturated sodium chloride solution (1:1) three times, Separate the oil layer.

[0093] Dilute the concentrated solution with 40g of petroleum ether, add a mixed adsorbent consisting of 5g of activated clay and 5g of silicon dioxide, perform adsorption at room temperature, filter out the activated clay and silicon dioxide, and recover petroleum ether by distillation.

[0094] Pour the concentrated solution after the above adsorption treatment into the feed liquid tank of the molecular rectifier, and carry out three stages of molecular distillation respectively to obtain the concentrated solu...

Abstract

The invention relates to a fish oil concentrate. The preparation method of the fish oil concentrate includes the processes of urea esterification and molecular distillation, and is characterized by including the following steps of (1) performing urea esterification on the raw material ethyl-esterified fish oil under the protection of nitrogen to obtain A; (2) adsorbing A with any two adsorbents inactivated clay, attapulgite and silicon dioxide under the protection of nitrogen to obtain B; (3) performing multistage molecular distillation on B to obtain C; (4) adsorbing C with any one or two adsorbents in activated carbon, activated clay, attapulgite and silicon dioxide under the protection of nitrogen to obtain the end product. The fish oil concentrate prepared by the method is low in anisidine value, small in impurity content, clear in color and high in stability.

Description

technical field [0001] The invention relates to a fish oil concentrate, in particular to a method for purifying an omega-3 polyunsaturated fatty acid concentrate from crude fish oil. Background technique [0002] Omega-3 polyunsaturated fatty acid (PUFA) is a physiologically active substance contained in fish oil that has a significant impact on human health and intellectual development. Its main components are eicosapentaenoic acid (EPA) and docosahexaenoic acid DHA has many functions such as inhibiting platelet aggregation, anti-thrombosis, relaxing blood vessels, regulating blood lipids, strengthening brain and intelligence, anti-cancer, anti-inflammation, etc. Therefore, the development of high-quality and high-purity PUFA is conducive to enhancing people's physical fitness , Improve the health level, and bring good economic and social benefits to the development of the marine fish oil industry. [0003] The methods for extracting EPA and DHA from fish oil mainly includ...
