Abstract

The invention discloses a production method for high yield ripened highland barley powder rich in gamma-aminobutyric acid. The method includes the following steps: placing highland barley seeds into agermination tank after pretreatment, and using sterile water to perform immersing for 3-4 h; pouring the sterile water in the germination tank, and performing germination culture for 24.0-26.8 h so that the seeds can be obtained; performing hot air baking and ripening treatment after the draining of the obtained highland barley seeds, and performing milling to obtain powder. The method studies the change rules of powder yield during the germination of the highland barley seeds, and selects appropriate germination conditions to perform follow-up ripening processing on the germination seeds; and the GABA enrichment ratio of the prepared highland barley ripened powder is 24-38%, and the powder yield is more than 80%, so that the loss of the powder during powder making can be greatly reduced,and the utilization rates of the seeds can be enhanced.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, and in particular relates to a production method of high-yield mature highland barley powder rich in gamma-aminobutyric acid (GABA). Background technique [0002] Highland barley, that is, naked barley (Hordeum vulgare L.var.nudum Hook F), is widely planted in the Qinghai-Tibet Plateau region of my country, and is a basic ration crop for the Tibetan people to survive. Highland barley has the characteristics of high protein, high soluble fiber elements, high vitamins, low fat, and low carbohydrates, and is rich in many important physiologically active substances, such as γ-aminobutyric acid. GABA is a non-protein natural amino acid with Lower blood pressure, promote sleep, enhance memory, anti-anxiety, regulate growth hormone secretion and other physiological functions. [0003] Studies have reported that the GABA content of highland barley grains (average value 15.28±8.51m...
