What should we pay attention to when purchasing food grade sodium hexametaphosphate?

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.

Therefore, when choosing and purchasing sodium hexametaphosphate, it must be strictly checked. How do food company choose sodium hexametaphosphate as food additive?

(1) Purchase varieties: Sodium hexametaphosphate purchased must be food grade, industrial grade sodium hexametaphosphate can not be used in food additives, it is necessary to strictly examine whether the manufacturers producing sodium hexametaphosphate have the relevant qualifications of food additive safety production, and can not let industrial grade serve as food grade.

(2) Scope of use: It must be used in accordance with the scope and amount of the national food additives, such as canned, fruit juice (fruit flavor) beverages and vegetable protein beverages, with a maximum usage of 1.0g/kg; aquatic products, dairy products, poultry products, meat products, ice cream, instant noodles, with a maximum usage of 5.0g/kg.

(3) Requirements for certificates: Copies of production licenses must be obtained from suppliers of food additives, and attention should be paid to the licensing items and the date of issuance. If compound food additives are used, they must be marked on the licence. There are also food factory inspection certificates or other certificates of conformity.

(4) Packaging labels: Food additives should have labels, instructions and packaging. Labels and instructions shall specify the name, specifications, net content, date of production, ingredient or ingredient list, name, address and contact information of the producer, shelf life, product standard code, storage conditions, matters related to production license number, and the scope, dosage and method of use of food additives. The label should say "food additives".

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
