Embodiment 1
[0039] Example 1 Preparation of Naked Oat Protein Hydrolysate
[0040] Including the following steps:
[0041] A. Take naked oat flour, add water of 12 times its mass, mix well, adjust the pH to 10.5 with NaOH solution with a concentration of 1mol / L, and ultrasonically treat it for 45min at a temperature of 45℃ and a power of 200W, 4000r Centrifuge for 20 minutes per minute, filter with 200 mesh filter cloth, take the supernatant, add 1mol / L HCl solution to adjust the pH value to 4.0, let stand for 10 minutes, centrifuge at 4000r / min for 20 minutes, take the precipitate, freeze-dry, and obtain the nectar Wheat protein
[0042] B. Take the naked oat protein, add water at a solid-liquid ratio of 10g / L, stir well, add 10% of the total weight of the solution with alkaline protease, and enzymatically hydrolyze for 6 hours at a temperature of 60℃ and a pH of 8.5. Keep the pH value of the solution unchanged, and after enzymatic hydrolysis is completed, the enzyme is inactivated at 100°C f...
