Phytic acid and its series products have strong chelating ability, which can form a very thin and strong organic phosphate film on the metal surface. At this point, the electrode potential of the metal has become the same as that of platinum and gold, thereby preventing the corrosion of the metal. Currently, phytic acid and its salts have been widely used in metal surface treatment. And it has been combined with other compounds to form metal surface passivators, metal surface coating agents, cyanide free electroplating additives and other products. It has played a significant role in the corrosion resistance of metals.
Phytic acid is widely present in plant seeds and is a natural nutrient. The most significant feature of phytic acid is its strong chelation with metal ions and antioxidant properties. This characteristic makes it widely applicable. In developed countries, phytic acid has been widely used in industries such as food, medicine, and chemical. In recent years, the development and utilization of phytic acid in China, especially as a food preservative, have attracted attention. Purpose: Adding 0.010.05% phytic acid to beverages can remove excessive metal ions. (Especially heavy metals that are harmful to the human body) have a good protective effect on the human body. 2. Adding phytic acid to a medium containing Monosporum can promote microbial synthesis and antioxidant activity. Adding phytic acid to the culture medium of lactic acid bacteria can promote their growth 3. Specific usage examples: Phytic acid 4%, caffeine 0.02%, potassium hydroxide 1.36%, anhydrous sorbitol 5.6%, magnesium oxide 0.48%, anhydrous glucose 80%, L-arginine 0.2%, anhydrous citric acid 3.6%, sodium chloride 2%, ascorbic acid 0.6%, sulfuric acid 0.2%, water 2.14%. This formula not only has a quick thirst quenching effect, but also is used for long-term consumption. It has the characteristics of being fresh, pleasant, sweet and palatable.
The main formula is as follows: (1) One part phytic acid; (2) Two parts citric acid; (3) Specifically: 4 kilograms of 50% phytic acid, diluted with 1000 kilograms of water; (4) Shelf life (at room temperature): Fruits (hard): 6-8 months Fruits (soft): 4-6 months Vegetables: 6 months old
Phytic acid, also known as cyclohexanol hexaphosphate, is a natural non-toxic chemical product extracted from grain crops. The special molecular structure and physicochemical properties of phytic acid determine its important application value in metal surface treatment. Especially in today's increasingly strengthened environmental protection, phytic acid products will inevitably occupy a very important position in metal surface treatment. 1. Protective mechanism of phytic acid 2. Application of phytic acid in metal surface treatment 3. Conclusion Phytic acid, with its unique physicochemical properties, can form a strong and dense protective film on metal surfaces, inhibit metal oxidation and corrosion, and is widely used in metal surface treatment. Improving product quality, reducing production costs, and minimizing environmental pollution have an immeasurable impact on enhancing economic and social benefits.
In wine production, due to the presence of certain metal elements in the raw materials and soil (adhering to the surface of grapes), as well as frequent contact between equipment, containers, and the wine body during production, a small amount of metal ions dissolve in the wine body. When the iron content in wine is too high, in an oxidizing environment, iron ions will produce black (reacting with tannins) or white (reacting with phosphates) precipitates, known as spoilage disease. Among the various methods of iron reduction treatment, phytic acid treatment is one of the most direct and safe methods. Phytic acid is extracted and refined from grains, safe and non-toxic. And it has the characteristics of low dosage, fast reaction speed, low cost, and easy operation.
