Embodiment 1

[0032] Put the cleaned purslane into a steaming container, heat it with a strong fire and steam it to the top, take it out, put it in a lyophilizer, freeze it to -20°C, evacuate it to a drying chamber pressure of 30Pa, heat sublimation, sublimation The temperature is controlled below 40°C, and the analysis temperature is controlled below 45°C until dry.

Embodiment 2

[0034] Blanch the purified purslane in boiling water for 2 minutes, take it out, put it in a freeze dryer, freeze it to -28°C, vacuumize it to a pressure of 50Pa in the drying room, and heat it for sublimation. The sublimation temperature is controlled at 50°C, and the analysis temperature is Control below 45°C until dry.

Embodiment 3
