Embodiment Construction

[0014] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail in conjunction with specific embodiments.

[0015] The invention aims at the problem that the processing effect of the tuna crude oil refining method in the prior art is unsatisfactory, and provides a tuna crude oil refining method.

[0016] A kind of tuna crude oil refining method that the embodiment of the present invention provides, comprises the following steps:

[0017] (1) Degumming, take a certain amount of crude oil in a beaker, add 0.05% antioxidant tertiary butyl hydroquinone in the beaker, place the beaker in a water bath and heat it to 70°C and keep stirring, add the degumming agent, stir Evenly, keep warm for 2min, then centrifuge at 4000rpm for 20min, the upper layer of the centrifugate is degummed fish oil; the degumming agent is compounded with citric acid, acetic acid, phosphoric acid and phytic...

Abstract

The invention provides a tuna coarse oil refining method. The method comprises the steps as follows: firstly, degumming; secondly, deacidification; thirdly, decoloration; fourthly, deodorization. According to the method, the degumming rate can reach as high as 5.35%, the degummed tuna oil is better in transparency, light in color, and has tinny fishy taste, and convenient for storage, and moreover, the technology required in the method is simple and convenient to realize, and has high practicability.

Description

technical field [0001] The invention relates to a method for refining tuna crude oil, and relates to the technical field of food processing. Background technique [0002] The basic components of deep sea tuna oil are Omega-3 series unsaturated fats EPA and DHA. EPA can reduce blood viscosity, dissolve excess fat in the blood vessel wall, reduce triglyceride and cholesterol (LDL) concentration, achieve the effect of clearing thrombus, lowering blood lipid, preventing and improving cardiovascular and cerebrovascular diseases, and is internationally recognized as "blood vessel cleansing". Doffer". DHA, another unsaturated fatty acid rich in deep-sea fish, is the material basis for brain cells. Lack of DHA will cause brain development disorders, memory loss, and senile dementia. Therefore, people call DHA "brain gold". DHA is very important to light stimulation. It has a high content in the brain, retina and other tissues. It is an important part of the human brain, eyes, var...
