Glucoraphanin, also known as radish glycoside, with the chemical formula C12H23NO10S3, is a thioside compound. Radish thioside looks like a white powder, which is soluble in organic solvents such as methanol and ethanol, and is insoluble in water. Radish thioside has the advantages of green environmental protection and high biological activity, and is widely used in the medical and health field. 

 In terms of raw materials, broccoili is the main raw material for radish thioside. China is a large agricultural country. It has a rich variety of crops and a huge planting area. The output of broccoli has maintained a growth trend for a long time. In 2024, the output of broccolia in China exceeded 9 million tons, setting a record high. At present, China's broccolia has been exported to many overseas countries and regions. Adequate supply of raw materials will provide favorable conditions for the development of the radish thioside industry. 

 In terms of technology, the preparation methods of radish thioside include chemical synthesis and biosynthesis. The chemical synthesis method is a traditional preparation method for radish thioside, which has the problems of complex preparation process, low yield and high operating cost. The biosynthesis method usually takes natural materials such as brocccoli seeds as substrates, adds amino acids and enzyme catalysts, and produces the finished product through full reaction. This method has the advantages of easy raw materials, green environmental protection, and good quality of finished products. It is the mainstream preparation method of radish thioside.
