What is the difference between industrial phosphoric acid and food phosphoric acid

What is the difference between industrial phosphoric acid and food phosphoric acid, and choosing the right type can easily double the efficiency

Food and industrial grade phosphoric acid are two important chemicals that are widely used in various fields. Then in the process of use, what are the differences between them, how to find a more suitable position?

1. Food grade phosphate

Food grade phosphoric acid is a colorless transparent or yellowish crystal with strong acidity and adsorbability. It can react with metal ions to form phosphate which is insoluble in water, so it is widely used in the food industry. The quality is stable and harmless to human body.

2. Industrial grade phosphoric acid

Industrial grade phosphoric acid is corrosive and acidic. The purity of industrial grade phosphoric acid is relatively low, but it has good catalytic property and stability, and is widely used in chemical industry, metallurgy, water treatment and other fields.

In the process of use, the scope of application of the two is not consistent. For example, food-grade phosphoric acid is a commonly used acid agent, which can enhance the acid taste of food and improve the taste of food. For example, adding the right amount of food-grade phosphoric acid to products such as beverages, candies, and condiments can give them a unique sour taste.

Secondly, it can be used as a buffer to maintain the freshness and taste of food. Adding food-grade phosphoric acid to products such as yogurt and jam can prevent food from spoiling. It can also react with metal ions in food to generate phosphate, which is insoluble in water, thereby reducing the heavy metal content in food.

Industrial grade phosphoric acid is widely used in chemical industry, such as the production of phosphate fertilizer, pesticides, dyes and so on. In addition, industrial grade phosphoric acid can also be used as a flame retardant, dehydrant, catalyst and so on.

In the field of metallurgy has an important role, such as for metal polishing, rust removal, pickling and so on. In addition, industrial grade phosphoric acid can also be used to extract metals, such as lead and tin from used batteries. It is also widely used in the field of water treatment, which can effectively remove suspended solids, sediments and microorganisms in water and improve water quality.

With the continuous expansion of the application fields of food and industrial grade phosphoric acid, the market demand is growing year by year. The market demand for industrial grade phosphoric acid has broad prospects, and the consumption upgrade of healthy, green and high-quality food also provides new opportunities for the food-grade phosphoric acid market.

In short, food and industrial grade phosphoric acid have a wide range of application prospects in various fields. In the context of growing market demand, enterprises need to continue to innovate and improve quality to meet the needs of the market!
