Selenium-rich nutrient solution for konjak planting and preparation methods of selenium-rich konjak refined flour and selenium-rich konjak protein powder

Abstract

The invention discloses a selenium-enriched nutrient solution for konjak planting. The nutrient solution comprises the following raw materials in parts by weight; 1 to 5 parts of seaweed selenium polysaccharide, 0.25 to 1 part of zinc lactate, 0.01 to 0.5 part of potassium dihydrogen phosphate, 0.05 to 0.3 part of boric acid, 0.1 to 0.5 part of ferric citrate, 0.2 to 0.6 part of an amino acid manganese complex, 0.05 to 0.3 part of a copper glycinate complex, 0.4 to 0.6 part of rare earth double salt, 0.05 to 0.1 part of organic germanium, 0.2 to 0.6 part of a calcium source, 0.01 to 0.2 part of zirconium oxide and 0.1 to 0.5 part of an absorption auxiliary agent. The invention further discloses a preparation method of a selenium-rich konjac fine powder and a selenium-rich konjac protein powder, the selenium-rich nutrient solution is applied, and the preparation method comprises the steps of preparation of the selenium-rich nutrient solution, konjac seed soaking treatment, fertilizationmanagement, processing of the konjac fine powder and konjac flying powder, peculiar smell treatment of the konjac flying powder, extraction of the selenium-rich konjac protein powder and the like. The konjak yield is high, the selenium content of the prepared konjak fine powder and konjak protein powder is high, and the additional value of konjak is improved.

Description

technical field [0001] The invention relates to the technical field of crop planting and processing, in particular to a method for preparing konjac planting selenium-enriched nutrient solution, selenium-enriched konjac fine powder and selenium-enriched konjac protein powder. Background technique [0002] Selenium is an essential trace element for humans and animals. It is known as "the fire of life", "the king of anti-cancer", and "the patron saint of the heart". It is an important component of some antioxidant enzymes and selenium-P protein in the human body Part of it plays an important role in human life activities. People can improve the body's immunity, disease resistance and delay aging through selenium supplementation. Since there is no long-term selenium storage organ in the human body, the selenium needed by the body should be continuously obtained from the diet in sufficient amounts. The balance of selenium concentration has an important protective and promoting ef...

Problems solved by technology

[0009] At present, the supply of konjac series products in the market is in short supply, the market is good, and the price is high

But there is no konjac flour containing selenium-enriched ingredients, and the existing preparation method has the problems of low flour yield and purity. After inquiry, there is no report identical with the technology of the present invention.
