[0028] After sorting and screening the almond meal, crush it with a wall breaker for 5 minutes, and pass through a 60-mesh sieve to obtain the sieved matter for use; take the above-mentioned sieved matter and mix it with deionized water at a material-to-liquid ratio of 1:5 (w / v) for preparation. Heat and stir in a water bath at 50°C for 5 minutes to form a semi-solid-liquid mixture. Use 2mol / L NaOH to adjust the pH of the mixture to 8.0, add alkaline protease protex 6L for 2 hours, and add 1% (w / v) for enzymolysis. After the end, the enzyme was deactivated in a boiling water bath for 10 minutes; the enzymolysis solution after deactivation was cooled for 10 minutes and subjected to high-speed centrifugation; Mix red dates and deionized water at a material-to-liquid ratio of 1:5 (w / v), soak in a water bath at 60°C for 1 hour, use a blender to crush and beat, pass through a 100-mesh sieve for use; take the above extract and place it in a water bath at 45°C In the pot, use 2.0mol / ...
