Description
Technical Field
The invention relates to the technical field of crop planting and processing, in particular to a selenium-rich flax planting method and a preparation method of selenium-rich flax powder.
Background
Flax is one of the important oil crops in China, except rich in polyunsaturated fatty acid- α -linolenic acid which is necessary for human bodies, the flax seeds also contain other important active ingredients, such as secoisolariciresinol diglucoside, dietary fiber and the like, the lignan content in the flax seeds is about 800 times of that of other common crops, the secoisolariciresinol diglucoside has the effects of resisting tumors and osteoporosis, relieving climacteric symptoms and the like, the flax seeds are also rich in soluble plant cellulose and have the effect of reducing cholesterol, and the incidence rate of diseases such as constipation, obesity, heart disease and the like can be reduced by frequently eating the flax seeds.
At present, the linseed is mainly used for squeezing the linseed oil, the product structure is single, and in the oil squeezing process, the flax lignans, dietary fibers, proteins and other nutrient substances are remained in the linseed cake and are mostly used as animal feeds and cannot be reasonably utilized. In addition, the sesame seeds are rich in nutrition and have extremely strong nut flavor after being baked. Therefore, in countries such as Europe and America, the sesame powder obtained by baking and grinding is one of common sesame foods, and can be added into foods such as yoghourt, oatmeal, salad and the like to improve the nutritional and health-care values of the foods and bring a fragrant nut flavor to the foods.
At present, in the selenium-rich crop planting technology, inorganic selenium is mostly used as a selenium source, after the selenium is absorbed by plants, only part of the selenium is converted in the plants to generate organic selenium, and part of the selenium cannot be converted and is accumulated in agricultural products in an inorganic state. Research shows that inorganic selenium has certain toxic side effect on human body.

s4, harvesting: when the flax leaves turn yellow, part of the flax leaves fall off, 75-80% of capsules turn white and yellow, and when the seeds are shaken, a cutter-rower is selected for harvesting; the cut flax is aired for 3-5 days and then threshed.
The invention also provides a preparation method of the selenium-rich flax powder, which comprises the following steps:
s1, timely airing or drying the harvested selenium-rich flax seeds, and mechanically cleaning to remove weed seeds, impurities and broken or unsaturated seeds;
s2, preheating the baking oven to 110-120 ℃, sprinkling the flax seeds on a baking tray, and putting the baking tray into the baking oven for baking for 10-12 minutes;
s3, selecting a pulverizer suitable for pulverizing materials with high oil content, and sieving with a sieve with a pore diameter of 1 mm to obtain the selenium-rich flax powder.
The invention has the following beneficial effects:
1. the invention relates to a flax selenium-rich planting method taking organic selenium as a selenium element source, and compared with inorganic selenium such as sodium selenite and the like, the organic selenium has the advantages of edible safety, no toxic or side effect, high absorption and utilization rate, high nutritional value and the like. In addition, the invention also provides a preparation method of the selenium-rich flax powder, and the obtained flax powder product has high organic selenium content and aromatic flavor, and the nutritional active substances such as fatty acid, secoisolariciresinol diglucoside, dietary fiber, protein and the like in the flax seeds can be effectively retained.
2. After the selenium-rich organic fertilizer is sprayed, the selenium content of the flax is greatly improved to 0.175-0.893mg/kg, and the yield of the flax can be increased by 2.6-11.5%;
3. the problem that active ingredients such as lignans, dietary fibers and the like in the flax seeds cannot be fully and reasonably utilized is solved, and the purpose of supplementing selenium for a long time for a human body in a mode of eating the flax powder can be achieved, so that the selenium deficiency condition of the human body is improved, and the health of the human body is promoted.
