Food and industrial grade phosphoric acid are two important chemical substances widely used in various fields. What are the differences between them during use, and how do you find a more suitable location.
1. Food grade phosphoric acid
Food grade phosphoric acid is a colorless, transparent or slightly yellow crystal with strong acidity and adsorption properties. It can react with metal ions to generate insoluble phosphates, and is therefore widely used in the food industry. Stable quality, harmless to the 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 activity and stability, and is widely used in fields such as chemical engineering, metallurgy, and water treatment.
In the process of use, the scope of application of the two is also not very consistent. For example, food grade phosphoric acid is a commonly used acidity agent that can enhance the acidity of food and improve its taste. For example, adding an appropriate amount of food grade phosphoric acid to products such as beverages, candies, and condiments can give them a unique sour taste.
Secondly, it can serve 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 spoilage. It can also react with metal ions in food to generate insoluble phosphates, thereby reducing the content of heavy metals in food.
Industrial grade phosphoric acid is widely used in the chemical industry, such as in the production of phosphate fertilizers, pesticides, dyes, etc. In addition, industrial grade phosphoric acid can also be used as a flame retardant, dehydrating agent, catalyst, etc.
It plays an important role in the metallurgical field, such as in the polishing, rust removal, acid washing, etc. of metals. In addition, industrial grade phosphoric acid can also be used to extract metals, such as lead, tin, etc. from waste batteries. It has a wide range of applications 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, market demand has been increasing year by year. The market demand for industrial grade phosphoric acid has a broad prospect, and the consumption upgrade of healthy, green, and high-quality food has also provided new opportunities for the food grade phosphoric acid market.
In summary, food and industrial grade phosphoric acid have broad application prospects in various fields. Against the backdrop of increasing market demand, enterprises need to constantly innovate and improve quality to meet market demands! If needed, please feel free to contact and communicate.
