Planting method for selenium-iron-rich bean sprouts

Abstract

The invention discloses a planting method for selenium-iron-rich bean sprouts. Through seed soaking with sodium selenite, the bean sprouts are promoted to germinate rapidly and selenium is provided; a water solution which contains ferric citrate and sodium selenite and has the pH value of 4.0-6.0 is sprayed during germination of the bud sprouts, and therefore iron and selenium are provided for growth of the bean sprouts. The bud sprouts planted through the method are high in selenium and iron content, free of iron fishy smell and stable in chemical property, and cannot generate the problems of discoloring, precipitation and the like in the food processing process.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a method for planting selenium-iron-rich bean sprouts. Background technique [0002] Iron is an essential trace element for the human body and an important component of hemoglobin, myoglobin, cytochrome and various oxidases. Iron can promote human development, enhance the body's resistance to disease, and regulate tissue respiration. Iron is also an important element of hemoglobin. Women and infants tend to lose iron in their bodies, and their iron intake is often insufficient, so they are more prone to iron deficiency. People usually add iron in food to solve the problem of iron deficiency in the human body, such as iron nutrition fortifier, which uses iron salt as an iron fortifier to produce iron-enhanced biscuits, beverages and other iron-fortified foods. Inorganic iron salts have a fishy smell after being used as food nutrition fortifiers, have poor ...

[0005] The Chinese patent library application number is 200310106732.0, which discloses the method of soaking seeds in iron salt and then germinating with water, or soaking seeds in iron salt solution and germinating to prepare iron-rich bean sprouts. The method uses iron salt to soak seeds, and iron also belongs to heavy metals. It will inhibit the germination rate of bean seeds and reduce the growth rate of bean sprouts

Ferrous ions are toxic to rice. The auto-oxidation of ferrous ions can produce superoxide free radicals. At the same time, the Fenton reaction involving ferrous ions can produce highly toxic hydroxyl radicals. Hydroxyl free radicals can trigger a series of chain reactions and attack Membrane lipids will eventually lead to membrane leakage and even complete destruction of the membrane, resulting in inhibition of plant growth (Zheng Guohong et al. Effects of iron and potassium soaking on rice seed germination characteristics [J]. Guizhou Agricultural Sciences, 2009, 37 (11) :51~53)

[0007] At present, the eutrophication of vegetables is mainly concentrated in the enrichment of a single trace element, and there are few patents for planting vegetables with eutrophication of multiple trace elements.
