Embodiment 1

[0071] The preparation process for improving black barley germination efficiency, active ingredient content and antioxidant activity of the present embodiment comprises the following steps:

[0072] Step 1. According to quality indicators such as color, volume and quality, select black barley grains with plump and uniform grains, no trauma and similar quality, clean the dust on the surface with ultra-pure water, and discard the scum;

[0073] Step 2, soak the black barley grains cleaned in step 1 with 0.1g / 100g sodium hypochlorite solution for 30s, and then wash them with sterile water for 3 times;

[0074] Step 3. Add hydrogen-rich water with a content of 1ppm to the black barley cleaned in step 2, and soak for 8 hours at 20-25°C. During soaking, the weight-to-volume ratio of black barley to hydrogen-rich water is 0.2:1;

[0075] Step 4. Keep the black barley soaked in step 3 at a temperature of 10°C with hydrogen-rich water with a content of 1ppm to keep it moist. The weight...

Embodiment 2

[0078] The preparation process for improving black barley germination efficiency, active ingredient content and antioxidant activity of this embodiment, the process flow chart is as follows figure 1 shown, including the following steps:

[0079] Step 1. According to quality indicators such as color, volume and quality, select black barley grains with plump and uniform grains, no trauma and similar quality, clean the dust on the surface with ultra-pure water, and discard the scum;

[0080] Step 2, soak the black barley grains cleaned in step 1 with 0.1g / 100g sodium hypochlorite solution for 30s, and then wash them with sterile water for 3 times;

[0081] Step 3. Add hydrogen-rich water with a content of 1.6ppm to 2.1ppm to the black barley cleaned in step 2, and soak at 15°C for 6 hours. During soaking, the weight-to-volume ratio of black barley to hydrogen-rich water is 0.4:1;

[0082] Step 4. Keep the black barley soaked in step 3 at a temperature of 10°C, 15°C and 25°C resp...

Abstract

The invention discloses a preparation technology method capable of improving the sprouting efficiency, active component content and anti-oxidization activity of black barley. The preparation technology method comprises the following steps: screening seeds; washing the seeds with clean water; disinfecting the seeds with sodium hypochlorite; washing the seeds with sterile water; immersing the seedswith hydrogen-rich water; culturing and sprouting. According to the preparation technology method disclosed by the invention, the seeds are immersed and wetted by the hydrogen-rich water; under the condition that the sprouting temperature of the black barley is relatively low, relatively high germinating potential, germinating rate and growth speed are obtained within short time. Compared with common sprouting conditions, the nutritional and active components and the anti-oxidization activity of the sprouted black barley are remarkably improved; the content of free plant phenolic acid, free polyphenols, calcium and iron of the sprouted black barley treated by the hydrogen-rich water is remarkably increased. The preparation technology disclosed by the invention is simple in preparation process and easy to operate and industrial large-scale production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and in particular relates to a preparation process for grain germination, in particular to a preparation process for improving black barley germination efficiency, active ingredient content and antioxidant activity. Background technique [0002] With the development of society, some grains need to realize their germination process according to different needs of people, such as the malt production used in the beer industry, the grain and malt in the processing of traditional Chinese medicine, the germination of rice before sowing rice, and the brown rice developed in recent years germination etc. Seed germination is the most intense period of life activities of higher plants, involving a series of morphological and physiological and biochemical changes, some macromolecular substances such as starch and protein will be decomposed, and the content of nutrients such as vitamins and minerals...
