Abstract
Soybean meal is an important component of poultry and fish feed formulations. Soybean cultivation and use date back to China's agrarian era. Its usage for human consumption is mentioned in Chinese medicinal collections reaching back 6,000 years. For generations, soybean has meant oil, bread, cheese, milk, and meat to the people of Indonesia, the Philippines, Manchuria, Korea, Japan, and China. Soybeans are an oilseed crop that provides food for wildlife, birds, and humans. Acetochlor and clomazone are two insecticides that are commonly employed to safeguard soybeans from weeds and are both highly problematic. The goal of this research was to see the effect of acetochlor and clomazone on soybean food safety. Employing UPLC-MS/MS (ultra-performance liquid chromatography coupled with tandem mass spectrometer), acetochlor and clomazone concentrations in mature straw, mature soybean, green straw, and green soybean were measured. The RSDs (relative standard deviations) range from 2-11%, the compound recoveries varied from 86-110% at various concentration levels. 0.01 mg kg-1 was the quantitation limit for each herbicide matrix. When taken at the prescribed dose, clomazone and acetochlor residues in soybeans were all less than 0.01 mg.kg-1 at harvest. Soybean is an oilseed crop and significant edible, as well as a valuable source of human nourishment.
