[0005] The Chinese patent application number 201210030102.9 introduces a processing method of selenium-enriched edible oil. The selenium-enriched yeast is mixed with a certain amount of lye by cooking, and then the mixture is added to the edible oil. Selenium-enriched edible oil needs to be filtered and other processes to produce precipitation, and the selenium content of selenium-enriched edible oil is uncontrollable
In addition, the patent application No. 201210328370.9 introduces the processing method of selenium-enriched high-grade edible oil. A selenium-enriched edible oil is formed by selecting the fruits or seeds of selenium-enriched crops through simple pressing and blending. However, the fruits or seeds of selenium-enriched crops Selenium usually does not exist in oil (but in vegetable protein), which causes selenium not to enter the pressed oil, and the selenium in the selenium-enriched edible oil described in this patent is usually not filtered thoroughly Substituted by residues, this results in very low selenium content in selenium-enriched vegetable oil obtained through pressing and is very unstable

[0026] (2) Add 20 grams, 50 grams, and 100 grams of the fat-soluble L-selenomethyl-selenocysteine ​​solution in the liquid state above into 100 liters of corn oil, heat and stir at 60°C for 30 minutes to prepare Organic selenium-rich corn oil, the selenium content of the finished organic selenium-rich corn oil is 200μg / L, 500μg / L, 1000μg / L respectively.

Embodiment 2

[0028] (1) Take 100 grams of food-grade emulsifier Span 40 and heat it to 70 ° C. After heating for 60 minutes, it will completely melt into a liquid, and then take 3 grams of L-selenomethyl-selenocysteine ​​and directly add it to the dissolved Stir and mix in the Span 40 liquid, and finally add 400 grams of Span 80 and continue heating and stirring for 6 hours until the liquid becomes clear, and L-selenomethyl-selenocysteine ​​mother liquor with a selenium content of 2550 μg / g is obtained.

[0029] (2) Take 8.89 grams, 22.22 grams, and 44.44 grams of the fat-soluble L-selenomethyl-selenocysteine ​​solution in the liquid state, add them to 100 liters of olive oil, and heat and stir at 60°C for 30 minutes to prepare Organic selenium-rich olive oil, the selenium content of the finished organic selenium-rich olive oil is 200μg / L, 500μg / L, 1000μg / L respectively.

Embodiment 3

[0031] (1) Take 100 grams of food-grade emulsifier Span 40 and heat it to 70 ° C. After heating for 60 minutes, it will completely melt into a liquid, and then take 5 grams of L-selenomethyl-selenocysteine ​​and directly add it to the dissolved Stir and mix in the Span 40 liquid, and finally add 500 g of Span 80 and continue heating and stirring for 6 hours until the liquid becomes clear to obtain a L-selenomethyl-selenocysteine ​​mother liquor with a selenium content of 3542 μg / g.

[0032] (2) Add 5.65 grams, 14.12 grams, and 28.23 grams of the fat-soluble L-selenomethyl-selenocysteine ​​solution in the liquid state above into 100 liters of soybean oil, heat and stir at 60°C for 30 minutes to prepare Organic selenium-rich soybean oil, the selenium content of the finished organic selenium-rich soybean oil is 200μg / L, 500μg / L, 1000μg / L respectively.

Abstract

The invention relates to a preparation method of organic selenium-rich edible oil. The preparation method comprises adding L-Se-methylselenocysteine into molten span-40, carrying out uniform stirring, adding span-80 into the mixture, carrying out stirring to obtain fat-soluble L-Se-methylselenocysteine, and uniformly mixing the fat-soluble L-Se-methylselenocysteine and edible oil to obtain the organic selenium-rich edible oil. Through selection of an appropriate emulsifier, the fat-soluble organic selenium is prepared from the L-Se-methylselenocysteine and the fat-soluble organic selenium and the edible oil are mixed to form the organic selenium-rich edible oil. The organic selenium-rich edible oil is uniform and transparent and realizes quantitative control of edible oil selenium content.

Description

technical field [0001] The invention relates to the field of edible oil processing, in particular to an organic selenium-rich edible oil and a preparation method thereof. Background technique [0002] Edible oil is the animal or vegetable fat used in people's food production process. During the cooking process, it can shorten the cooking time of food, improve the color and flavor of food, and increase the nutritional content of food at the same time. Edible oil has become an indispensable non-staple food in people's daily life, and some edible oil even has certain health care functions. [0003] Selenium is one of the indispensable trace elements for the human body, and has a great relationship with the health of the human body. The Chinese Nutrition Society has listed selenium as one of the 15 essential nutrients for the human body, but 72% of my country's regions are still in the low-selenium or selenium-deficiency zone. Appropriate selenium supplementation can improve t...
