3. The production process of the selenium-enriched flour as claimed in claim 1, which mainly comprises the following steps:

selecting fresh high-quality purple sweet potatoes and purple sweet potatoes, cleaning, peeling, slicing, soaking in coconut oil for 1-2 hours, taking out, draining, adding water, cooking, cooling, taking out, and freeze-drying at-15 to-20 ℃ to obtain freeze-dried purple sweet potato powder and purple sweet potato powder;

cleaning fresh high-quality hawthorn, performing microwave drying at the constant temperature of 40-55 ℃ for 1.5h, adding the hawthorn into a pulverizer, pulverizing, and sieving with a 40-60-mesh sieve to obtain hawthorn coarse powder; adding water, stirring, standing for 24 hr, drying the fructus crataegi coarse powder solution until the water content is 5-10%, and breaking cell wall of fructus crataegi coarse powder with air flow to obtain ultramicro fructus crataegi powder with particle size of 5-10 μm;

weighing ultramicro hawthorn powder, purple sweet potato powder, taro powder, selenium-rich malt powder, composite flour modifier, soft white sugar and edible iodized salt according to the parts by weight, adding into a mixer for premixing, and mixing at the rotating speed of 30r/min for 5-10 minutes to obtain premixed powder;

adding the wheat flour into the premixed flour according to the weight part ratio, mixing for 25-30 minutes at the rotating speed of 15r/min, and then conveying and packaging to obtain the finished selenium-rich flour.

Technical Field

The invention belongs to the technical field of food, and particularly relates to a production formula of selenium-rich flour and a production process of the selenium-rich flour.

Background

There are forty countries and regions around the world that belong to areas with selenium deficiency. China is a large selenium-deficient country, and according to the atlas of local diseases and environmental factors of the people's republic of China, the China obliquely penetrates from the three provinces of northeast to the cloud plateau, and a low-selenium zone exists in 72% of the soil area of China, wherein 30% of the low-selenium zone is a serious selenium-deficient area. Because 72% of the soil in China is deficient in selenium, the selenium content of grain crops such as wheat, rice, corn and the like serving as main grain crops in natural foods is lower than 40 mu g/kg, the daily selenium intake of Chinese people is lower than the minimum intake of 50 mu g recommended by the world health organization, and the daily selenium intake is only 30-45 mu g and is lower than that of countries such as Japan, Canada, USA and the like.

Therefore, how to add the selenium element into the food in daily life is a problem which needs to be solved urgently, and the existing some selenium-containing prepared flour is often prepared by mixing various coarse grains, has common taste and is not beneficial to digestion, so that the selenium element is still difficult to be absorbed and utilized by the human body.

Disclosure of Invention
