Adding food grade sodium hexametaphosphate to ice cream can improve taste

 Summer will be coming. Ice drinks and ice cream are popular again. Especially ice cream is not only beautiful in appearance and eye-catching, but also very sweet in taste. However, ice cream can only improve its taste by ensuring its swelling capacity, increasing its volume, strengthening emulsification and dyeing to prevent crushing of paste. At this time, a food additive, sodium hexametaphosphate, is needed.


When it comes to food additives, don't be afraid. Especially the application of food phosphates is very fast in food processing, mainly for water retention agents, quality improvers, pH regulators, fermentation leavening agents. The taste, variety and color that food brings to people are a kind of enjoyment. Some beans, canned fruits and vegetables, including ice cream and many other foods, look pretty, attractive color, and add food grade sodium hexametaphosphate can achieve all of this.


Sodium hexametaphosphate has strict dosage regulations in food additives and is safe to use within the specified range. Because sodium hexametaphosphate has strong chelation, buffering and dispersion effects on metal ions, it can promote protein coagulation, and can be mixed with other phosphates to form a composite phosphate. It can also be used alone.


Sodium hexametaphosphate has the ability to form soluble complexes for certain metal ions such as calcium and magnesium. In the complex, the sodium atom in the sodium hexametaphosphate anion is replaced by Ca2+ and Mg2+ and other high-valent cations. Its solubility is greatly affected by temperature. At 20 °C, its solubility is 963.2g/kg, while at 80°C, the solubility is as high as 1744/Kg (equivalent to two kilograms of product dissolved in one kilogram of water), but its dissolution The speed is slow, the aqueous solution is acidic, and it is easily hydrolyzed to form orthophosphate in warm water or acid-base solution. The hydrolysis process is irreversible, and the degree of hydrolysis is related to temperature and PH value.


The amount of sodium hexametaphosphate added in food is clearly stipulated. The maximum amount of sodium hexametaphosphate added is 1.0g/kg. In addition, the content of fluorine, lead, arsenic and other ions in the product is also clearly required (one millionth) to ensure the safety of food. Therefore, although the use of food grade sodium hexametaphosphate in ice cream can play the role of chelating, changing the PH value, emulsifying and dispersing, improving the ionic strength of food and increasing the volume of ice cream, it must be added strictly in accordance with the standard of 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
