Problems solved by technology

[0003] In the cod liver oil extraction methods of the prior art, there is no method for extracting cod liver oil from monkfish liver, but when other cod liver oils such as silver carp fish oil and hairtail fish oil are extracted, the extraction rate is low, the investment cost is high, solvent residues, and fish oil quality decrease and other technical issues

Embodiment 1

[0029] A method for extracting Ankang cod liver oil, specifically comprising the steps of:

[0030] (1) Thaw the freshly frozen monkfish liver, wash it, remove the sundries, and drain the surface water;

[0031] (2) Stir the monkfish liver into fat paste with a beater, take 90.13g of fat paste into a conical flask, add 100g of water and stir to mix evenly, put it in a water bath and stir to raise the temperature to 40-50°C, then use Adjust the pH value to 9 with an aqueous solution of sodium hydroxide with a concentration of 10% by mass, stir and heat up to 80°C, then add 3.1546g of sodium chloride to carry out hydrolysis and salting out for 20 minutes, and then centrifuge at a speed of 4500r / min for 15 minutes in a high-speed centrifuge Afterwards, absorb the orange-yellow transparent liquid in the upper layer to obtain 72.1401g of crude oil, that is, cod liver oil after crude extraction;

[0032] The amount of above-mentioned sodium chloride used, water is calculated by wei...

Abstract

The invention relates to an extracting and refining method of Monkfish liver oil, and belongs to the technical field of aquatic product intensive processing. With Monkfish livers as raw materials, the fish liver oil is extracted from the Monkfish livers by a light alkali hydrolysis and then is refined. The extracting method comprises the following steps of cleaning fresh Monkfish livers, removing impurities, stirring to form a fat paste, degrading protein by a light alkali solution, destroying the combination relation between protein and fat, separating out fat, extracting crude fish liver oil, degumming by phosphoric acid, de-acidifying by sodium hydroxide, de-coloring by activated clay and deodorizing in vacuum, extracting high-quality fish liver oil. The method is simple, the cost is low, the extracting efficiency is high, and the quality of the fish liver oil is good.

Description

technical field [0001] The invention relates to a method for extracting ankang cod liver oil, which belongs to the technical field of aquatic product processing. Background technique [0002] Monkfish is an offshore bottom fish, which is distributed in the western part of the North Pacific Ocean and is produced in the coastal waters of my country. It has extremely high nutritional and medicinal value. In recent years, due to the reduction of economic fish, the market position of monkfish has become more and more significant, and the output and price have increased significantly. The export of monkfish has become a new fishery in my country. However, monkfish has a large head, small body, large viscera, and a low meat yield. In the process of processing, more than 60% of the leftovers can be produced. Apart from being simply used as raw materials for fish feed, most of these leftovers are not used. Discarded directly after treatment, causing environmental pollution and waste...
