Embodiment 1

[0048] A production method for ripening highland barley whole powder, comprising the following steps:

[0049] (1) Take the highland barley grains equivalent to 1 / 6 of the volume of the horizontal germination tank, remove the impurities, mildewed grains and broken grains therein, to ensure the purity of the grains and the fullness of the grains;

[0050] (2) using the sodium hypochlorite solution with a concentration of 0.5% by mass to inject the highland barley grains of step (1) into the horizontal germination tank, the ratio of the solution volume to the dry weight of the grains is controlled at 3.0mL / g, and after soaking at 25°C for 30min Drain off the sodium hypochlorite solution, inject enough sterile water into the germination tank to circulate and clean 3 times;

[0051] (3) Maintain the ratio of sterile water volume to grain dry weight in the germination tank at 5.5mL / g, the temperature in the tank at 25°C, and stand for 4.0h soaking;

[0052] (4) Remove the soaking ...

Embodiment 2

[0058] A production method for ripening highland barley whole powder, comprising the following steps:

Abstract

The invention discloses a method for producing high-yield mature highland barley whole powder rich in γ-aminobutyric acid. The method comprises the following steps: after the highland barley grains are pretreated, they are placed in a germination tank, and soaked in sterile water for 3 times. ~4h; then pour out the sterile water in the germination tank, germinate and cultivate for 24.0~26.8h to obtain grains; drain the obtained highland barley grains, carry out hot air baking and curing treatment, and finally grind to obtain powder. In the present invention, the variation law of the yield of powder material during the germination of highland barley grains is studied, and suitable germination conditions are selected to carry out subsequent maturation processing of the germinated grains, and the GABA enrichment rate of the prepared highland barley cooked powder is 24-38% , the powder yield is above 80%, which can greatly reduce the powder loss in the milling process and improve the utilization rate of grains.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, in particular to a method for producing high-yield mature highland barley whole powder rich in γ-aminobutyric acid (GABA). Background technique [0002] Highland barley, or naked barley (Hordeum vulgare L.var.nudum Hook F), is widely planted in the Qinghai-Tibet Plateau of my country and is the basic food crop for the survival of the Tibetan people. Highland barley has the characteristics of high protein, high soluble fiber element, high vitamin, low fat and low carbohydrate, 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 15.28±8.51mg / 100g) is much higher than ...
