Embodiment 1

[0027] Embodiment 1, 5 kilograms of raw material eel bones are cleaned with clear water, then put into a pot together with 5 kilograms of water, and heat while stirring. When the temperature rises to 45° C., 2.5 grams of papain and 40° C. Prepare a solution with a concentration of 2.5%, add it to the pot and continue stirring and heating. When the temperature rises to 55°C, keep the temperature for 3 hours. After 3 hours, the enzymolysis ends, and the temperature is raised to 75°C to kill the enzyme, and then Stop heating, stand still for 4 hours, oily matter floats on the liquid surface after standing, extracting the oily matter floating on the liquid surface is about 800 grams. Then take 800 grams of water and add it to the oil and stir it for 20 minutes, then let it stand still, take out the oil floating on the liquid surface after standing still, repeat the process of adding water-stirring-standstill-extracting, and then extract the oil floating on the liquid surface The o...

Embodiment 2

[0030] Embodiment 2, 8 kilograms of raw material eel bones are cleaned with clear water, then put into a pot together with 16 kilograms of water, and heat while stirring. When the temperature rises to 55° C., mix 6.4 grams of papain with 40° C. Prepare a solution with a concentration of 2.5%, add it to the pot and continue stirring and heating. When the temperature rises to 60°C, keep the temperature for 5 hours. After 5 hours, the enzymolysis ends, and the temperature is raised to 85°C to kill the enzyme, and then Stop heating, stand still for 5 hours, the oily thing floats on the liquid surface after standing, extracting the oily thing floating on the liquid surface is about 1400 grams. Then take 1400 grams of water and add it to the oil and stir it for 20 minutes, then let it stand still, extract the oil floating on the liquid surface after standing still, repeat the process of adding water-stirring-standstill-extracting, and then extract the oil floating on the liquid surfa...

Embodiment 3

[0033] Embodiment 3, on the basis of Embodiment 1 or 2, in addition to sulfuric acid, acids such as citric acid and hydrochloric acid can also be added in the eel bone fish oil extraction process.

[0034] The product that the method for making according to the specific embodiment of the present invention and embodiment is through Zhongshan School of Medical Public Health Central Laboratory and Shanghai Institute of Preventive Medicine inspection, and its detection result is:

[0035] Central Laboratory of Zhongshan School of Medical and Public Health:

[0036] The average value of alkoxyglycerol contained in 1000 mg of eel bone fish oil is 600 mg.

[0037] Shanghai Academy of Preventive Medicine:

[0038] The average value of alkoxyglycerol contained in 1000 mg of eel bone fish oil is 800 mg.

Abstract

A fish oil prepared from eel bone contains alkoxyl glycerol CH2OH-CHOH-CH2-OR2 EPA and DHA. Its preparing process includes washing eel bone with water, extracting out crude oil, purifying the crude oil and obtaining fish oil of eel.

Description

technical field [0001] The invention relates to a fish oil and a production method thereof, in particular to a fish oil produced from eel bones as a raw material and a production method thereof. Background technique [0002] Eel, also known as river eel, is a downriver migratory fish that lives in seawater and freshwater. Its meat is rich in a variety of high-quality proteins, and its bones are rich in a variety of unsaturated fatty acids, which have high health and nutritional value. my country is a big eel meat processing country, and its output accounts for 90% of the world's total output. There must be a large amount of eel bones left after processing. At present, the utilization of the remaining eel bones is still in the extensive processing stage, such as making bone powder as Feed use; or use a simple method to produce fish oil (crude oil), the resulting product contains more impurities and moisture, and is prone to rancidity. Another consequence of simple processing i...
