Microelement culture solution and method for increasing microelements of pea sprouts with same

Abstract

The invention discloses a microelement culture solution and a method for increasing microelements of pea sprouts with the same. The microelement culture solution is a solution containing one or more of 0.3-0.6 mg / L of zinc sulfate, 300-500 mg / L of organic selenium and 200-400 mg / L of germanium dioxide. The method for increasing the microelements of the pea sprouts comprises steps as follows: firstly, pea seeds are soaked in the microelement culture solution and then cultured, and the microelement culture solution is sprayed once every 12-24 h during culture. Compared with the prior art, the microelement culture solution and the method have the advantages as follows: the microelements of the cultured pea sprouts are high in enrichment degree, the microelement culture solution can also promote growth of the pea sprouts, production is not limited by seasons, the production cycle is short, the cost is low, the benefit is high, and the pea sprouts are natural and pollution-free.

Description

technical field [0001] The invention relates to the technical field of preparation of functional food, in particular to a trace element culture solution and a method for increasing trace elements of pea sprouts. Background technique [0002] Most of the existing enrichment of trace elements is concentrated in wheat, tea, Ganoderma lucidum or other edible fungi, and trace elements in sprouts have also been studied and reported, but most of them are for the enrichment of trace elements, and an optimal method cannot be considered. method to increase the content of trace elements. Chinese patent document ZL201010203459.3 discloses a "production method of sprouted vegetables enriched with one or more trace elements", which dissolves salt compounds of trace elements in a certain amount of clear water to prepare sprouted vegetables culture medium, but this method does not take into account an optimal condition for the growth of sprouts. At the same time, sodium selenite is used as...

Problems solved by technology

[0002] Most of the existing enrichment of trace elements is concentrated in wheat, tea, Ganoderma lucidum or other edible fungi, and trace elements in sprouts have also been studied and reported, but most of them are for the enrichment of trace elements, and an optimal method cannot be considered. The method of increasing the content of trace elements

Chinese patent document ZL201010203459.3 discloses a "production method of sprouted vegetables enriched with one or more trace elements", which dissolves salt compounds of trace elements in a certain amount of clear water to prepare sprouted vegetables culture medium, but this method does not take into account an optimal condition for the growth of sprouts. At the same time, sodium selenite is used as the selenium-enriched culture medium in this patent, and the inorganic reagents of selenium all have strong Toxic, so there is a certain risk in the culture medium

It has been found through experiments that different concentrations of trace element culture solutions have an impact on the growth of seeds and sprouts, and a certain concentration of trace elements will affect the growth cycle, yield and physiological indicators of sprouts, which may promote or may affect the growth of sprouts. Inhibit the growth of sprouts

Moreover, if the enrichment of trace elements is too high, which exceeds the range that the human body can bear, it will be too much, and it will cause harm to the human body, which violates the original intention of functional food
