Problems solved by technology

Studies have shown that when plants are subjected to adversity stresses such as hypoxia, hypoxia, cold shock, heat shock, salt stress, and mechanical stimulation, the content of γ-aminobutyric acid (GABA) in plants will increase to a certain extent, but γ-aminobutyric acid The increase in content cannot be stably controlled

Abstract

A method for increasing the content of γ-aminobutyric acid in germinated peanuts. Select well-grown peanuts, wash away the dust with clear water, then wash with distilled water, and drain; soak and disinfect with sodium hypochlorite solution, wash with distilled water, and place in a safe place. Under light conditions, soak in water; after the soaked peanuts are pulsed with strong light, wash them with distilled water, add water of the same quality as the peanuts, soak them in dark conditions to make them germinate; spray distilled water, and wait for the peanuts to germinate The sprouts grow to 10 mm to 25 mm to obtain germinated peanuts, and the enzymes are inactivated; they are vacuum freeze-dried and vacuum-packed, and stored in a cold storage below 10°C. Using pulsed strong light physical treatment, easy to operate, can increase the activity of enzymes, activate protease and glutamic acid decarboxylase in peanuts, accelerate protein decomposition, enhance the growth and stress resistance of peanut seeds, and the GABA content of germinated peanuts can reach More than 280mg / 100g.

Description

technical field [0001] The invention relates to a method for increasing the content of gamma-aminobutyric acid in germinated peanuts, in particular to a method for increasing the content of gamma-aminobutyric acid in germinated peanuts by using pulsed strong light. Background technique [0002] When plant seeds are exposed to adversities such as drought and flood, low temperature, hypoxia, heat shock, cold shock, and machinery, they often suffer from different degrees of damage, which leads to changes in plant physiological and biochemical processes, and then affects the production of nutrients. Under adversity conditions, the plant body will be harmed, such as the reduction of water absorption capacity of the plant body, the lack of water in the body, and the increase of growth inhibitory substances. [0003] The metabolic intensity in plant seeds is closely related to their stress resistance. Appropriate intensity and physical energy can accelerate the metabolic process an...
