Is expansion agent harmful to human body?

At present, swelling agent is widely used in China, which is a plant growth regulator approved by the state. Long-term use practice has proved that it is harmless to human body. \ x0d \ x0d \ swelling agent, commonly known as "fruit swelling dragon" or "swelling hormone", is called cytokinin and belongs to plant hormone chemicals. The common filler is clofenuron, commonly known as Clopidogrel in English, abbreviated as CPPU(N-2- chloro -4- pyridylbenzene -N'- phenylurea), which belongs to phenylurea substances and mainly stimulates cytokinins. It was first developed by Sandoz company in Switzerland and invented by Shouteng, a professor of pharmacy at the University of Tokyo. CPPU was developed by Japan Concord Fermentation Industry Co., Ltd., but CPPU was developed in. 1980, with the approval of Japan Plant Regulator Research Association, Concord Fermentation started the nationwide effect test in Japan under the name of KT-30. 1March, 1989, Xiehe fermentation obtained the patent \x0d\ bulking agent with the trade name \ フルメット _(0. 10%) \ which is harmless to human health and has been listed as unnecessary toxicity in many developed countries. However, excessive use or improper use will cause fruit deformity, fruit cracking, fruit drop and other phytotoxicity. \x0d\ In order to protect human health, FAO and WHO have formulated norms and guidelines for pesticide safety assessment, and developed countries such as Europe and America have also established strict risk assessment systems. On the basis of drawing lessons from international standards and the experience of developed countries, China has established a relatively perfect pesticide safety evaluation system. Many developed countries, such as the United States and Japan, have included it in the list of substances without toxicity management, and there is no need to set safety limit standards for its residues. 20 1 1, there is no scientific evidence that it will cause harm to human health.
