1. Cleaning: Soak the picked fruit of Ipomoea batatas in clean water and gently knead it to remove the dirt on the surface. Don't rub hard, so as not to damage the burr on the surface of the fruit.
2. Disinfection: put the washed sweet potato fruit in boiling water for 1-2 minutes, take it out and drain it. Disinfection can effectively sterilize and prolong the fresh-keeping period of fruits.
3. Storage: Store the packaged sweet potato fruit in a dry, cool and ventilated place at a storage temperature of 5℃- 10℃. Do not put it together with other fruits or vegetables to avoid odor.
