The organic selenium-enriched plant salt is prepared by taking the table salt a carrier and adding a fixed amount of high-selenium broccoli extracting liquid and is stable in selenium content and safe in selenium form, and a healthy and scientific selenium supplementing choice is provided for broad selenium-deficiency people.
Description
Technical field
The present invention relates to a kind of preparation method of organic selenium-rich plant salt.
Background technology
Selenium is one of trace element needed by human, for maintaining the vital movement of people to play an important role, with people
Body health has substantial connection, with cancer-resisting, improve body immunity, remove free radical, protection optic nerve, cardioprotection and
Liver, prevent from producing the critical functions such as toxicant in vivo.The Keshan disease of the mankind, hepatopathy, anaemia, coronary heart disease, Kaschin-Beck disease, sugar
More than the 40 kinds of diseases such as urine disease, cancer are closely related with scarce selenium.According to the investigation of the Chinese Academy of Agricultural Sciences, the area of China 72% lacks
Selenium seriously lacks selenium, and scarce selenium crowd is up to 1,000,000,000 or so, and (day, selenium intake was less than the minimum day intake recommendation of Chinese Soclety of Nutrition
60μg).Additionally, as environmental pollution is increasingly serious, causing pneumonia, liver cancer, cancer of the stomach etc. to become compatriots' malignant diseases occurred frequently.Selenium conduct
It is a kind of can effectively antagonism heavy metal, strengthen human body anti-cancer ability, protect heart protect liver functional mass, cause extensively in various fields
General concern.
Broccoli (Brasicaoleracea L.var.italicaPlench) is rich in various mineral matters beneficial to human body
Element, also containing the abundant vitamin with antioxidation activity, Polyphenols and flavonoids, can reduce lung cancer, prostate cancer
Risk.MT Roberge etc. (Journal ofAgriculture and Food Chemistry, 2003) research has shown that,
Broccoli has good enrichment to selenium, the inorganic selenium more than 90% of absorption can be converted into into Organic Selenium, and protein selenium is rich
The main occurrence form of selenium in selenium broccoli.Chinese invention patent ZL20111042626251.2 discloses a kind of selenium-rich broccoli
Vegetable material and its breeding method, selenium exists with methylselenocysteinefrom form in the vegetable material of acquisition, and with selenium first
Content of the selenium that base selenocysteine form is present in the vegetable material is 2.5mg/kg-2500mg/kg, accounts for total selenium and contains
More than the 80% of amount ratio.Therefore, the high selenium broccoli of Jing reinforcement techniques plantation can be used as the splendid material for extracting organism organic selenium
Material.
Salt is flavoring the most frequently used in culinary art, is to one of most important material of human survival, with widely available
The characteristics of, and at regular time and quantity, inexpensive, the important carrier for having enriched the iodine as the whole people.China is a state for generally lacking selenium
Family, uses for reference the precedent that the whole people enrich the iodine, and people can realize mending the healthy living of selenium at regular time and quantity by taking in organic selenium-rich salt.
The content of the invention
To solve above-mentioned technical problem, it is an object of the invention to provide a kind of organic selenium-rich plant salt and preparation method thereof,
Using salt as carrier, add quantitative high selenium broccoli extract and prepare a kind of organic selenium-rich plant salt, its Se content is steady
Fixed, Se form safety, the benefit selenium for providing health science for vast scarce selenium crowd is selected.
A kind of preparation method of organic selenium-rich plant salt of the present invention, comprises the following steps：
Salt and high selenium broccoli extract are mixed, mixture is obtained, after being dried organic selenium-rich plant salt is obtained, wherein
