Matters needing attention in the preservation of washed broken vegetables

1. Preserve washed Senecio scandens, and avoid exposure to sunlight and high temperature. Excessive temperature will lead to the loss of water in ground vegetables, resulting in deterioration of ingredients. Therefore, it is best to put the ground vegetables in a cool and ventilated place, such as the vegetable fresh-keeping room or storage box in the refrigerator.

2. Ground vegetables are vulnerable to pests, especially in summer. Therefore, in order to prevent the occurrence of pests, vegetables can be put in sealed fresh-keeping bags or wrapped with plastic wrap. This can effectively isolate the air from pests and extend the shelf life of local vegetables.

3. If the chopped vegetables need to be preserved, they can be placed in a transparent plastic box covered with a layer of wet tissue. Then wrap the whole box with plastic wrap. Wet tissue can keep the humidity of vegetables on the ground, prevent them from drying and keep them fresh.
