For cleaning water pipes, I believe that everyone has a certain understanding, in fact, the so-called cleaning water pipe is to wash out the dirt accumulated inside the water pipe after long-term use, the bacteria and harmful substances that breed. But there is one important thing that must not be left untouched to wash out all these dirty things, and that is food grade citric acid!
What is Citric Acid? In fact, citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystalline water, odorless, has a strong sour taste, easily soluble in water. Its calcium salts are easier to dissolve in cold water than in hot water, and this property is often used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, makeup industry, etc.
When we clean the water pipes, we usually add food-grade citric acid, because after all, this is related to the health of the whole family. Then many people have asked: "What is the role of citric acid?" ”
In fact, citric acid is mainly used as sour taste agent, solubilizer, buffer, antioxidant, deodorant, flavor enhancer, gelling agent, toner and so on. In addition, citric acid also inhibits bacteria, protects color, improves flavor, and promotes sucrose conversion. Citric acid also has chelating properties, which are able to remove certain harmful metals. Citric acid prevents oxidation caused by enzyme catalysis and metal catalysis, thereby preventing the discoloration and flavor change of frozen fruit. Citric acid is often used as an acidulant for drinks, a small amount of citric acid will not produce any toxic side effects for the human body, but also can promote the metabolism in the body.
Finally, let's talk about how we want to distinguish the true and false of food-grade citric acid:
Citric acid has the effect of removing minerals from water. Citric acid appearance is colorless crystalline or white crystalline powder. Citric acid is a common ingredient in some masks and lotions. Citric acid Citric acid is an organic acid widely used in chemical cleaning, and is a trivalent acid in aqueous solutions. The main raw material of citric acid is corn.
Citric acid or citrate as a builder can improve the performance of washing products, can quickly precipitate metal ions, prevent contaminants from reattaching to the fabric, and maintain the alkaline nature necessary for washing. Sodium citrate is used as a preventative finisher in dairy products. Citric acid is allowed in jams, beverages, cans and cannies in our country. Sodium citrate is used industrially to effectively remove ferrous non-ferrous metal surface oxidizers as a metal purifier.
