Desc：With the change of poultry farming industry from quantity to quality and benefit, the research and development of poultry functional feed and feed additives will become an inevitable trend in the development of poultry feed industry and an effective measure to promote the healthy and sustainable development of poultry farming industry. Now there are a lot of pig feed additives on the market, functional additives, nutritional additives, pharmaceutical feed additives and general additives. When farmers choose, they need to be cautious.

Desc：In everyday life, whether you buy drinks or snacks carefully selected, they contain food additives. Sodium hexametaphosphate in food additives improves the quality of food and prolongs its shelf life, while condiments such as salt, soy sauce, vinegar, monosodium glutamate, sugar, anise, pepper and mustard are used everyday, which is different from food additives.

Desc：Water retention agent refers to a kind of substance which can improve the stability of the product, maintain the water holding capacity of the food and improve the shape, flavor and color of the food in the process of food production and processing. In order to help maintain water content in food, substances added are usually used in meat and aquatic products processing to enhance water stability and high water holding capacity of phosphate. Sodium tripolyphosphate is one of the water retention agents.

Desc：The use of food additives should be safe and effective, and the most important thing is to ensure safety. In addition to meeting relevant standards and regulations, such as hygienic standards for the use of food additives, quality standards for food additives and good production and operation standards, the most important thing is to ensure that the intake of added food additives does not exceed the daily allowable intake and the additions during production and processing. Food grade sodium hexametaphosphate is no exception. It is also the basis of the amount of food additives added in food processing.

Desc：With the development of society, great changes have taken place in the pattern of food consumption, which has gradually changed from home-made and near-home purchasing to eating delicacies all over the world without leaving home. Food additives play an important role in this respect. If sodium hexametaphosphate is to be a food additive, strict scientific experiments are needed to ensure its safety. The long-term and large-scale edible effects have been considered in the experiment. This "large amount" can be described as "eating sodium hexametaphosphate as a meal". The "long-term" is measured by the length and strength of "lifelong" and "daily" as the scientific basis for standard-setting. Therefore, as long as it is used according to the standard, its safety is not enough to worry about.

Desc：Inhibitory mud, such as lime mud, gypsum mud, calcium chloride mud and potassium-based mud, was widely used in mud shale formation to prevent collapse and stabilize borehole lining in the 1960s, which played a good role in treating unstable rock formations in water. Since the 1970s, the anti-collapse mud composed of polymer and potassium salt has been recognized as an ideal system, and nowadays potassium formate drilling fluid system has been widely used.
