A kind of selenium-rich edible blend oil and preparation method thereof
Technical field
The present invention relates to field of health care food, in particular to a kind of selenium-rich edible blend oil and preparation method thereof.
Background technique
China is the big oil seed production state in third place in the world, and vegetable oil resource is abundant, and routinely division vegetable oil resource, which removes, includes
Outside the crops resource such as soybean, peanut, rapeseed, sesame, flaxseed, sunflower seed, cottonseed, further include xylophyta oil resource such as
Oil tea, oil palm, coconut, olive, walnut etc., in addition rice bran, maize germ etc. are also good vegetable oil resource.
With stepping up for living standards of the people, the production and consumption amount of China's edible vegetable oil has apparent increasing
It is long, an important sources of the edible vegetable oil as energy in people's daily life and nutrient, to its main nutrient composition rouge
Fat acid must have a deep understanding, while with the gradually reinforcement of people's health consciousness, quality of the people for edible oil
And the content of fatty acid of edible oil and the concern of ratio also start slowly to enhance, and also have proposed meet health requirements in the world
The ratio of dietary fatty acid, such as saturated fatty acid: monounsaturated fatty acids: the ratio of polyunsaturated fatty acid is about 1:1:1, N-
The ratio of 6:N-3 is about (5~10): 1, DHA:EPA ratio is about (5~10): 1.
Increase N-3 how unsaturated rouge in diet in nutrition and health field, some research institutions and expert advice at present
The intake of fat acid, and the further exploration of the optimal proportions problem about N-6 and N-3.This is because in diet N-6 with
The balance of N-3 ratio helps to reduce the generation of cardiovascular disease and other chronic diseases, is conducive to normal growth and development.Cell
Albumen is gene-determined, and the composition of cell membrane polyunsaturated fatty acid is then largely dependent upon dietary int ake.This two
Kind polyunsaturated fatty acid, which must distinguish between, to be treated, because they are respectively to have feature in metabolism and function, can not mutually be replaced,
There is also mutual competition and inhibition for some aspects.N-6 and the balance of N-3 polyunsaturated fatty acid in vivo are for stablizing cell
Film function, maintains cell factor and lipoprotein balance, cardiovascular disease resistant, enhancing development etc. to rise at controlling gene expression
Important role.
From the point of view of resident's total fat acid consumption, saturated fatty acid and monounsaturated fatty acids and polyunsaturated fat
Acid ratio tend to balance, but in polyunsaturated fatty acid N-6 and N-3 ratio serious unbalance, N-3 polyunsaturated fatty acid
Take in wretched insufficiency.In order to overcome current resident to consume uneven problem to dietary fatty acid, preparing ready-mixed oil makes its fatty acid
The lipid nutrient balance for meeting health of people needs to greatest extent is a long-term project.
Selenium element is one of the essential trace elements of the human body.China is the more serious country of selenium deficiency, is caused because selenium lacks
Endemic disease involve northeast to southwest more than ten a province and municipalities.It has been found that Keshan disease and Kaschin-Beck disease with lack selenium have it is close
Cut relationship, Keshan disease mostly occur growth and development childhood, be with 2~6 years old it is common, Kaschin-Beck disease is also few with children and blueness
Year is multiple.In addition, it is common there are also children mental retardation, cancer, cardiovascular disease, hepatopathy, cataract, fecundity decline,
More than 40 disease such as prostate cancer is related with selenium deficiency.
Prevention selenium deficiency can by tonic, build up one's health by taking tonic two kinds of approach and complete to supplement.Containing the food that selenium is more in daily life
There are dried marine products, kidney of animal etc..But modern life is busy, if tonic is excessively high to type requirements, selenium-supply approach is not enough just
