Embodiment 1
[0021] Embodiment 1: prepare green plum freeze-dried powder A
[0022] Wash the fresh greengage, peel and remove the core, mix according to the ratio of greengage pulp and water 1:4, stir evenly, treat it at a microwave power of 300W to a temperature of 50°C, add 16000U / g cellulase for enzymatic hydrolysis Insulated and extracted for 20 minutes, allowed to stand, filtered after cooling to obtain the filtrate. The filtrate was placed at -56° C. and the vacuum degree was 26 Pa to carry out freeze-drying treatment until the greengage freeze-dried powder had a constant weight. Put the powder in the package, vacuumize it, and freeze it in a -10℃~-20℃ refrigerator for later use.
Embodiment 2
[0023] Embodiment 2: Preparation of green plum freeze-dried powder B
[0024] Wash the fresh greengage, peel and remove the core, mix according to the ratio of greengage pulp and water 1:4, stir evenly, treat it at a microwave power of 500W until the temperature is 55°C, add 16000U / g cellulase for enzymatic hydrolysis Insulated and extracted for 30 minutes, left to stand, filtered after cooling, to obtain the filtrate. The filtrate was placed at -56° C. and the vacuum degree was 26 Pa to carry out freeze-drying treatment until the greengage freeze-dried powder had a constant weight. Put the powder in the package, vacuumize it, and freeze it in a -10℃~-20℃ refrigerator for later use.
Embodiment 3
[0025] Embodiment 3: Preparation of perilla leaf active extract A
[0026] Wash the fresh perilla, place it in a lyophilizer at -56°C and a vacuum of 26 Pa, freeze-dry it to constant weight, take it out, and pulverize it in a dry grinder, according to the mass ratio of perilla leaf powder to water: 1: 30 for proportioning, leaching, dissolving, filtering to remove the filter residue, and getting the filtrate. Then put it in a refrigerated environment at 4°C to stand still, filter it twice, and remove the final filtrate to be the perilla leaf active extract.
