What is sodium chlorophenoxyacetate?

Sodium chlorophenoxyacetate is a white needle-like or prismatic crystal with a slight phenolic taste. Soluble in water, stable in nature and not deteriorating after long-term storage. After acidification, p-chlorophenoxyacetic acid is generated, which is dissolved in organic solvents such as ether and ethanol. Sodium 4- chlorophenoxyacetate is an intermediate of meclofenoxate, a central nervous system stimulant, which was originally used for plant growth regulation [1]. Domestic trade names are Fangluosu and Baoguoling. 4- chlorophenoxyacetic acid can promote biosynthesis and biotransformation in plants, which can not only prevent flower and fruit falling, improve fruit setting rate, increase fruit growth rate, promote early maturity, but also improve plant quality, and has the function of herbicide [2]. However, due to its cumulative toxicity to human body, the national standard cancelled its application for production license as a food additive.

Bean sprouts are one of the vegetables deeply loved by consumers. Rich in vitamin C, amino acids, retinol, dietary fiber and other components beneficial to human body, and low in fat and cholesterol. It is suitable for the "three highs" population and is conducive to regulating the unhealthy diet structure. Moreover, it decomposes most of protein in mung beans into amino acids in the growth process, which is more conducive to human absorption. Sodium 4- chlorophenoxyacetate (4-CPANa), commonly known as anticonvulsant, is a common plant growth inhibitor in agricultural production. As a substitute drug for 2,4-D, it has overcome the side effects such as poor concentration control and deformity of 2,4-D, with less cumulative toxicity and gradually occupied a larger market share.

Sodium 4- chlorophenoxyacetate is widely used in bean sprout production, which can promote the crude extraction of bean sprouts, reduce root germination and accelerate cell division. According to the research, it has no obvious teratogenic effect on rats (wistar), but it has some damage on mature sperm cells of mice (Kunming). Mung bean sprouts are a kind of vegetables with high consumption, and the harm caused by the accumulation of sodium 4- chlorophenoxyacetate residues in human body can not be ignored.

Poisonous bean sprouts appearing in the market are harmful to human body. They look fresh, but they contain at least four illegal additives, and urea seriously exceeds the standard. By adding various additives, urea, etc. Bean sprouts are even in size and white in color, most of them have no roots and look beautiful, which greatly improves the yield of bean sprouts. Poisonous bean sprouts mainly contain rootless bean sprouts (rootless agents), plant growth regulators, thickeners, 6- benzylamino adenine and other hormone additives. , urea content seriously exceeded the standard.
