Divide the fruit into cans of different sizes and add sugar water.

After canning, remove the gas in the tank with steam at 98- 100℃ for about 10 minutes. When the central temperature of the can reaches above 85℃, the can can be sealed and sterilized.
Third, the method of self-made canned kiwifruit
If you want to eat canned kiwifruit, you can buy finished products on the market or make canned kiwifruit at home. The method of homemade canned kiwifruit is:
1. Choose high-quality kiwifruit, and leave it for a day or two after picking, so it is not soft.
2. Wash, peel and cut kiwifruit. There is no fixed size requirement, which is convenient for you to eat.
3. Prepare a clean cooking pot, pour a proper amount of water, boil the water, add the cut kiwi fruit and cook for 5 minutes, then add rock sugar and cook for 5 minutes, and turn off the fire.
The canned food should be disinfected when cooking, scalded with boiling water several times, and then dried. If possible, put it in the oven for hot air drying, then put the kiwi fruit in the jar while it is hot, tighten the seal, completely cool it and put it in the refrigerator for preservation.
