Problems solved by technology

[0007] At present, lipid-lowering products are mainly divided into two parts: one is lipid-lowering drugs, such as Xuezhikang, Su Jiangzhi, Compound Danshen Tablets, Gynostemma Gynostemma Total Soap Tablets, Di’ao Xinxuekang, etc., mainly in this category, generally Chinese medicinal materials, etc. Raw materials, however, are three-point poisonous drugs, which will damage internal organs while treating them; the other type is health products with lipid-lowering effects, such as spirulina, lecithin, fish oil, etc. The lipid-lowering fish oil is mainly for general Deep sea fish oil, single active ingredient

Embodiment 1

[0027] Extraction and Refining Technology of Eel Oil

[0028] a. Extraction:

[0029] Add 0.5 parts of 2mol / L dilute HCl aqueous solution to 1 part of eel, heat to 80-95°C, and filter the extract;

[0030] b. Separation:

[0031] Centrifuge and filter the extract to obtain the oil phase; add sodium hydroxide and warm water to wash until neutral, and then centrifugally filter again to obtain the oil phase; degumming, decolorizing and centrifugal separation to obtain crude eel oil;

[0032] c. Alkali treatment:

[0033] According to the volume ratio of crude eel oil: ethanol solution = 1:4, add ethanol solution containing 4% NaOH to the crude eel oil, adjust to PH=10, heat to 78°C, add saponification solution, and cool to 25°C, then centrifuge Filter to get the filtrate.

[0034] d. Refrigeration:

[0035] Refrigerate the filtrate at -30°C for 36 hours, take the filtrate after centrifugal filtration, and recover the ethanol under reduced pressure to obtain the oil;

[0036...

Embodiment 2

[0039] The mass percentage content of each composition in the eel oil extract that the method for embodiment 1 makes is:

[0040] The total content of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is 34%, where EPA / DHA=1:(2~2.5);

[0041] Hexadecetonic acid 9.09%, octadecadienoic acid 25.81%, octadecadienoic acid 5.75%, octadecadienoic acid 1.21%, eicosatraenoic acid 2.02%, docosapenta Acenoic acid 4.75%; other components, such as dodecanoic acid, myristic acid, tetradecynoic acid, pentadecanoic acid, hexadecanoic acid, etc., account for 17.37%.

Embodiment 3

[0043] The mass percentage content of each composition in the eel oil extract that the method for embodiment 1 makes is:

[0044] The total content of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is 50%;

[0045] Hexadecenoic acid 8%, octadecaenoic acid 28%, octadecadienoic acid 3%, octadecatrienoic acid 1%, eicosadonic acid 1%, docosapenta Acrylic acid 3%;

[0046] Other ingredients, such as tetradecyenoic acid, octadecanoic acid, eicosa-1-enoic acid, etc. account for 6%.

Abstract

The eel oil extract contains eicosapentaenoic acid and docosahexaenoic acid in 34-50 %, and hexadecylenic acid, oleic acid, linoleic acid, elacomargaric cid, eicosatetraenoic acid and docosapentaenoicacid in 45-55 %. The present invention also discloses the preparation process of the eel oil extract and blood fat reducing health product with the extract. The eel oil extract of the present invention has the functions of inhibiting platelet aggregation, lowering cholesterol, preventing cardiac and cerebral vascular diseases, etc.

Description

technical field [0001] The invention relates to the technical field of lipid-lowering health care products. Background technique [0002] In the past two decades, with the rapid development of the national economy, the food consumption of Chinese people has undergone great changes. Although the dietary composition is still dominated by plant-based foods, the consumption of animal-based foods and oils has increased significantly. Consumption of plant-based foods such as cereals and tubers is on the decline. The most significant effect brought about by the changes in the dietary structure of Chinese people is the continuous increase in the incidence of hyperlipidemia. [0003] According to epidemiological investigations, the prevalence rate of hyperlipidemia in my country is more than 7% (among adults over 30 years old, the ratio of hyperlipidemia is about 10-20%). The general trend is that the north is larger than the south, and the city is larger than the countryside. At ...
