Abstract

The invention discloses a method for improving the content of the bioactive substance quercetin of buckwheat sprouts through magnetic field induction treatment. The method comprises the following steps of: firstly performing induction treatment on buckwheat grains by means of a magnetic field; and then sprouting the induced buckwheat grains for 7 days, thereby obtaining the buckwheat sprouts containing high content of the bioactive substance quercetin. The method for improving the content of the bioactive substance quercetin of the buckwheat sprouts through the magnetic field induction treatment provided by the invention is capable of obviously improving the activity of phenylalnine ammonialyase (PAL) and chalcone isomerase (CHI) in the sprouting process of the buckwheat while improving the sprouting percentage and germinative force of the buckwheat grains, thereby obviously improving the content of the bioactive substance quercetin in the buckwheat.

Description

technical field [0001] The object of the present invention is to provide a method for improving the content of quercetin, a bioactive substance of buckwheat germ, by using magnetic field induction treatment. [0002] Technical principle of the present invention [0003] Through the use of magnetic field physical means, during the germination process of buckwheat seeds, the activities of endogenous enzymes such as phenylalanine ammonia lyase (PAL) and chalcone isomerase (CHI) are stimulated, thereby improving the biological activity of buckwheat germs—queer Cortex content. Background technique [0004] Buckwheat is a dicotyledonous plant unique to my country for both medicine and food. Buckwheat contains protein, B vitamins, quercetin and other biologically active substances, mineral nutrients and plant cellulose. Biologically active substances such as quercetin are strong antioxidants, which can effectively remove oxygen free radicals in the body, help the body improve blo...
