Therefore, the vegetables that can be peeled, such as loofah, pumpkin, etc. should be peeled before consumption.
6, sunlight exposure method: the exercise of sunlight in the multispectral effect, dissection damage to vegetables in the sector residual pesticides. According to the measurement, fresh vegetables, fruits in the sun for 5 minutes, organochlorine, organic mercury pesticide residue loss of up to 60%
7, storage method: over time, pesticides in the air can be slowly dissected into harmless substances to humans. Therefore, some easy to store vegetables, can be stored through a quasi-time to reduce the amount of pesticide residues.
