Sodium tripolyphosphate - uncover the truth of misunderstanding of food additives

 There is a saying in the food industry: Without food additives, there would be no modern food industry. Take a correct view of the food additive sodium tripolyphosphate, add it within the prescribed range of use, and control the correct amount of use, it is harmless to human health and can be eaten with confidence.


There are many rumors on the Internet that food grade sodium tripolyphosphate is bad, saying that there are traces of heavy metals such as arsenic, lead, etc., and arsenic can cause systemic chronic poisoning mainly due to skin depigmentation, coloration, keratinization and cancer. There is also a certain amount of fluoride. Low concentrations of fluoride can cause chronic poisoning and skeletal fluorosis, reduce the calcium in the bones, and lead to bone sclerosis and osteoporosis. We just want to say that you don't understand food additives and food grade sodium tripolyphosphate.


Today, let's uncover the misunderstanding of the misunderstanding of the food additive sodium tripolyphosphate. First of all, understand the principles of the use of food additives.

1. It should not cause any health hazards to the human body.

2. The spoilage and deterioration of food should not be concealed.

3. Should not cover up the quality defects of the food itself or in the processing process, or use food additives for the purpose of adulteration, adulteration, or forgery.

4. The nutritional value of the food itself should not be reduced.

5. On the premise of achieving the expected effect, reduce the amount of use in food as much as possible.


Then sodium tripolyphosphate as the food additive has undergone strict toxicity evaluation to ensure safety. How is the safety evaluation of food additives carried out?


China has a unified food safety toxicity evaluation procedure and method, which is revised according to the provisions of the United Nations Codex Alimentarius Commission. Toxicity evaluation has about four stages: acute toxicity test, genetic toxicity test, sub-chronic toxicity test, and chronic toxicity test. After four tests, there is no toxicity before evaluation and selection as food additives. Through these four tests, a maximum non-effect dose is determined, the intake will not cause toxicity, and a maximum daily intake without any toxic manifestations is obtained.


In addition, not anyone or any company can produce food grade sodium tripolyphosphate, and its technology and overall management level must be supervised and evaluated. Only after passing the evaluation and issuing the license can it be produced.

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
