Background technology
Vegetables, fruit are the indispensable food of people's life, and agricultural chemicals is the important means of current prevention and elimination of disease and pests.Therefore having, fruit and vegetable surfaces there are to some extent residues of pesticides.The common method of removing fruit and vegetable residual pesticide has:
1. soaking and water washing method: most agricultural chemicals are insoluble in water, the method only can be except the pollution by pesticides of minute quantity, very little to the residues of pesticides effect of removing in fruit-vegetable food.
2. decortication method: the limitation of this method is to remove the residues of pesticides on part melon and fruit surface, and more vegetables are but had no idea.
3. storing method: although agricultural chemicals is with increasing memory time, have the effect of slow decomposition, because the natural degradation of a lot of agricultural chemicals even go up a century for up to decades, so method is consuming time oversize, impracticable.
4. cleaning agent, detergent clean: average cleaning rate is 15%, and cleaning agent all contains chemical surfactant, take in for a long time, human body is produced to the property accumulated and poison.Have expert to point out, when not getting washing agent acid-base value clear, clean fruit-vegetable pesticide residues, these medicaments are often with alkalescence, and some organophosphor, under alkaline environment, decomposes the toxicity producing and than originally, exceeds 10 times.
5. solar radiation method: can make part remains of pesticide in vegetables be decomposed, destroy, after processing like this, persticide residue can decline 60%, but in a lot of occasions, this method is inconvenient.
