Desc：For ordinary consumers, it may be difficult to see the variety of food additives. Therefore, when choosing and purchasing processed food, there is a relatively simple and safe way, that is, we must pay attention to the selection of all kinds of food produced by regular manufacturers. Because regular manufacturers use additives in strict accordance with national regulations to regulate their production and consumption, as well as the purchase of food additives are very strict, so the food you see contains sodium hexametaphosphate is not necessarily a bad thing?

Desc：Speaking of food additives, we all know that food additives are used to improve the color, aroma and taste of food, adjust the nutritional composition of food and prolong the shelf life of food. But when it comes to the use of sodium hexametaphosphate in food processing, many people may not know. Today, CDchem will tell you about the source, classification and use of the food additive sodium hexametaphosphate.

Desc：In the trade environment of "one belt and one road", the importance of logistics is beyond doubt. For those who like online shopping, express logistics is really familiar. The logistics information of packages can be directly seen in the current common application of electronic commerce platform, which shows that logistics plays an important role in the direct sales of products by electronic commerce and manufacturers of sodium hexametaphosphate.

Desc：Food additives are synthetic or natural substances added to food to improve the quality of food such as color, aroma and taste, and to meet the needs of preservation and processing technology. The processing of food and the use of additives must conform to the Food Safety Law, and no chemical substances other than food additives can be produced from non-food raw materials. As one of the food additives, sodium tripolyphosphate is not added randomly in food.

Desc：At present, there are two kinds of Potassium Fertilizers on the market, one is potassium chloride and the other is potassium sulfate. In addition, potassium formate, as a compound fertilizer of phosphorus and potassium, is used as topdressing fertilizer. In recent years, some production units and business units have been seeking violence. Because of the price of potassium formate, some fake and inferior potassium formate is used as foliar fertilizer to enter the market, which not only brings harm to agricultural production, but also affects the factories that actually produce potassium formate. A simple method for identifying true and false potassium formate is described as follows:

Desc：It is difficult to judge the quality of fertilizer because there are too many factors involved. It is fair to say that the mother-in-law is reasonable. The quality of potassium fertilizer can not be judged by the type of potassium, because there are too many factors involved. The ranking in the industry is mainly determined by price: potassium chloride < potassium sulfate < potassium nitrate < potassium carbonate < potassium dihydrogen phosphate < potassium formate < potassium polyphosphate < potassium phosphite. Because the nutrient composition of potassium fertilizer is very different in form and content, and there is no comparability between them, what are the application techniques of potassium fertilizer?
