Embodiment 1

[0024] 110kg DHA microalgae oil (containing 38% DHA) is pumped into the mixing tank through a delivery pump, 22kg of coarse-pore chromatography silica gel is added, stirred for 30min under vacuum and 50° C., and it is pumped into a blade filter through a delivery pump to filter, so that The oil is separated from the silica gel, and the oil is pumped to the bag filter for fine filtration to further remove the residual silica gel, and then the oil is transported to the oil blending tank. According to the formula ratio, set the metering pump, pump the corresponding 9890.2kg soybean oil and 2kg vitamin E into the oil blending tank, stir at room temperature and nitrogen for 5 minutes to mix evenly, and then pump the oil into the nitrogen filling production line for filling. Get DHA fortified nutritional soybean oil products.

Abstract

The invention relates to a preparation method for DHA (Docosahexenoic Acid)-fortifiedsoybean oil. The preparation method comprises the step of adding treated DHA microalgae oil and natural vitamin E into soybean oil under a nitrogen charging condition, wherein the treated DHA microalgae oil is the DHA microalgae oil after being subjected to chromatography silica gel treatment to remove free fatty acid and peroxide, and filtering. According to the preparation method provided by the invention, in order to solve the problem of the increasing of peroxide value and acid value after the DHA microalgae oil is stored for a period of time and in order to prevent the DHA microalgae oil added into the soybean oil from being further oxidized and acetified, the DHA microalgae oil is treated by the chromatography silica gel before being added, so that the peroxide and the free fatty acid are adsorbed and removed from oil, and the storing stability of the DHA microalgae oil after being added into the soybean oil is ensured.

Description

technical field [0001] The invention relates to the field of edible oil processing. Background technique [0002] DHA (docosahexaenoic acid) is an omega-3 polyunsaturated fatty acid, commonly known as brain gold, and is an essential fatty acid with important physiological regulation functions for the human body. It can promote brain development of infants, improve memory, lower blood fat, lower blood pressure, lower cholesterol, prevent cardiovascular diseases such as coronary heart disease, improve brain function, protect retina, improve vision, fight cancer, treat bronchitis, prevent and treat diabetes, and delay aging and other physiological functions. In view of this, many countries in Europe and the United States have formulated a daily DHA intake standard, ranging from 160-400mg / day, and my country has not yet formulated a standard for the daily recommended intake of DHA. At present, the per capita intake in our country is only 40mg / day, which is far lower than the r...
