Problems solved by technology

[0017] However, there is a lack of an efficient method for extracting and purifying omega 3 unsaturated fatty acids from tilapia orders in the prior art, and the extraction process of omega 3 unsaturated fatty acids in the prior art often also causes damage to the structure of omega 3 unsaturated fatty acids. Destruction loses its original function, and the omega-3 unsaturated fatty acids extracted in the prior art often find residues of organic solvents

Embodiment 1

[0034] The preparation method for extracting omega-3 unsaturated fatty acid from tilapia order specifically comprises the following steps:

[0035] (1) Wash the tilapia with rice vinegar and deionized water, and grind the cleaned tilapia;

[0036] (2) Add an appropriate amount of deionized water to the tilapia treated in step 1 and then microwave for 30 minutes; (3) heat the tilapia treated in step 2 to 60-90°C in a water bath and keep The temperature is 30~60 minutes, stirring continuously during the process;

[0037] (4) Centrifuge the tilapias treated in step 3 at 5000r / min for 5 minutes, remove the sediment, and take the liquid;

[0038] (5) Add the liquid obtained in step 4 to 10% rice vinegar solution, then centrifuge at 5000r / min for 5 minutes, and take the upper liquid;

[0039] (6) Vacuum the upper layer liquid obtained in step 5 at 70°C for 10 minutes to perform supercritical CO2 extraction and purification treatment to obtain omega-3 unsaturated fatty acids. The ...

Embodiment 2

[0041] Example 2 According to the evaluation of the effect of the extracted omega 3 unsaturated fatty acids in implementation 1

[0042] In order to verify the effect of this patented product, the applicant of this patent recruited 200 volunteers who had taken omega-3 unsaturated fatty acids and expected to improve their health through long-term free donations to try to change the use of this product. The statistics of the feedback of the volunteers are as follows:

[0043] Question Results Statistics

[0044]The survey results show that 84.5% of the volunteers highly agree with the effect of the omega-3 unsaturated fatty acid extracted by the patented method.

Abstract

The invention discloses a preparation method for extracting omega-3 unsaturated fatty acids from tilapia eyes. The preparation method comprises the following steps: (1) washing and cleaning the tilapia eyes with uniformly-mixed rice vinegar and deionized water, and grinding the cleaned tilapia eyes; (2) adding a proper amount of deionized water into the treated tilapia eyes in the step (1), and carrying out microwave oscillation for 30 minutes; (3) heating the treated tilapia eyes in the step (2) to 60 to 90 DEG C in a water bath, and maintaining the temperature for 30 to 60 minutes under continuous stirring; etc. The preparation method for extracting the omega-3 unsaturated fatty acids from the tilapia eyes designed by the invention has the advantages of high efficiency, no toxicity, no residue, no pollution, etc., and does not use harmful substances and organic solvents like acetone in the process of production.

Description

technical field [0001] The invention relates to the technical field of extraction and preparation methods for omega-3 unsaturated fatty acids, in particular to a preparation method for extracting omega-3 unsaturated fatty acids from tilapia orders. Background technique [0002] People often use the idiom "fish eyes to confuse pearls" to imply that fish eyes cannot be compared with pearls. In fact, in terms of nutritional efficacy, tilapia can even surpass pearls. In Japan, tilapia was put on the high-end dining table a long time ago, and the price is extremely expensive. [0003] The mystery has been uncovered by medical research. It turns out that tilapia is rich in nutrients, the important ones are calcium, phosphorus, iron and a variety of unsaturated fatty acids including omega-3 unsaturated fatty acids. Calcium and phosphorus have obvious effects on improving bone density and preventing rickets and osteoporosis. Iron is an indispensable trace element for the human bo...
