Embodiment 1
[0026] A kind of preparation method of sweet orange peel powder, it specifically comprises the following steps:
[0027] (1) Separation: Wash the peel of sweet orange (origin in Florida, USA) with clean water to clean the sediment and impurities, cut the peel into small pieces of 1×1cm with a knife, and take the upper layer of 0.8mm of the epidermis to obtain the oil cell layer;
[0028] (2) Drying: Pre-freeze the oil cell layer at -20 °C for 20 h, place it in a vacuum freeze dryer, and freeze-dry it for 24 h at a temperature of -45 °C and a vacuum of 20 Pa to obtain a freeze-dried sample;
[0029] (3) Pulverization: Put the freeze-dried sample into a refrigerated high-frequency vibration ball mill for vibration ball milling. The temperature is always kept at -4°C. The diameter of the vibrating steel ball is 1.5 cm, and the rotation speed is 1000 r / min. obtain a powder sample;
[0030] (4) Sieving: Sieve the powder sample with a 20-60 mesh sieve to make it reach the required ...

[0037] A kind of preparation method of sweet orange peel powder, it specifically comprises the following steps:
[0038] (1) Separation: Wash the peel of the sweet orange (origin in Brazil) with clean water to clean the sediment and impurities, cut the peel into 1×1cm pieces with a knife, and take the upper 0.6mm of the epidermis to obtain the oil cell layer;
[0039] (2) Drying: The oil cell layer was pre-frozen at -25°C for 30 hours, placed in a vacuum freeze dryer, and freeze-dried at a temperature of -50°C and a vacuum of 30 Pa for 36 hours to obtain a freeze-dried sample;
[0040] (3) Pulverization: Put the freeze-dried sample into a refrigerated high-frequency vibration ball mill for vibration ball milling. The temperature is always kept at -4°C. The diameter of the vibrating steel ball is 1.5 cm, and the rotation speed is 1500 r / min. obtain a powder sample;
[0041] (4) Sieving: Sieve the powder sample with a 60-100 mesh sieve to make it reach the required particle siz...
Embodiment 3
[0048] A kind of preparation method of sweet orange peel powder, it specifically comprises the following steps:
[0049] (1) Separation: Wash the peel of the sweet orange (produced in Jiangxi) with water to clean the sediment and impurities, cut the peel into small pieces of 1×1cm with a knife, and take the upper layer of the epidermis 1.0mm to obtain the oil cell layer;
[0050] (2) Drying: The oil cell layer was pre-frozen at -15°C for 15 hours, placed in a vacuum freeze dryer, and freeze-dried at a temperature of -40°C and a vacuum of 15 Pa for 18 hours to obtain a freeze-dried sample;
[0051] (3) Pulverization: Put the freeze-dried sample into a refrigerated high-frequency vibration ball mill for vibration ball milling. The temperature is always kept at -4°C. The diameter of the vibrating steel ball is 1.5 cm, and the rotation speed is 500 r / min. obtain a powder sample;
[0052] (4) Sieving: Sieve the powder sample with a 20-40 mesh sieve to make it reach the required part...
