Problems solved by technology

[0004] With the research on DHA by scientific and technical personnel, it is found that due to its active nature, it will quickly undergo automatic oxidation and deterioration when exposed to the air, and even produce a fishy smell, thus affecting the taste and nutritional value of the product.
In order to solve this problem, commonly used antioxidants or antioxidant aids such as conventional oils, vitamin E or vitamin C are added, but its antioxidant effect is general, and DHA and common vegetable oils are blended oils as main raw materials, and its nutritional components Single, unreasonable fatty acid ratio, difficult to be fully absorbed by the human body, and the effect on intellectual development is not obvious

Abstract

The invention discloses high-stability plant blend oil containing rich DHA (docosahexaenoic acid) and a preparation method of the plant blend oil. The plant blend oil is prepared from raw materials inpercentage by weight as follows: 0.5%-1.2% of DHA, 20%-30% of chia seeds, 20%-30% of grape seeds, 10%-20% of safflower seeds, 10%-20% of peony seeds, 10%-20% of camellia seeds and 10%-20% of sea buckthorn seeds. The plant blend oil is not prone to oxidation, has very high stability and can greatly meet the market demands.

Description

technical field [0001] The invention relates to an edible blending oil, in particular to a highly stable plant blending oil rich in DHA and a preparation method thereof. Background technique [0002] DHA (docosahexaenoic acid) is a long-chain omega-3 fatty acid distributed throughout the body. More specifically, it is the main building fat of the brain and eyes and an important component of the heart. Accumulating research data show that DHA plays a very important role in maintaining health in all stages of life. [0003] To maintain the normal functions of various tissues, the human body must ensure that there are sufficient fatty acids. If they are deficient, they can cause a series of symptoms, including growth retardation, abnormal skin scales, mental retardation, etc. As an essential fatty acid, DHA has more significant effects on enhancing memory and thinking ability and improving intelligence. Population epidemiological studies have found that people with high DHA ...
