Fytic acid - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| What is phytic acid? | phytic acid, also known as hexaethoxide hexaphosphate, exists in plant seeds in the form of calcium phytate and the like in nature. Phytic acid was extracted from rice bran and chaff. Because of its unique chemical properties and physiological functions, phytic acid has been widely used in food, medicine, metal processing, polymer industry, daily chemical industry and so on. Its molecule contains six phosphoric acid groups (12 free hydrogen), it is easy to combine with multivalent ions complexation reaction, complexation reaction is the formation of complexes. Value acid has a very strong complexation, can form insoluble complexes, so there will be a wide range of functions and uses. as an important natural substance, phytic acid is widely found in legumes, cereals, dried fruits, vegetables and fruits, especially in seeds, the seed is used to store phosphorus (at least 80% of the phosphorus in the grain is in the form of phytic acid), which has good stability and is not easy to rot. If it is combined with certain minerals such as magnesium, calcium, iron, zinc and other cations, the formation of phytate and fixed, therefore, phytate is a key factor in phosphorus nutrition and mineral nutrition. |
| skin care efficacy and function | value the principle of acid in skin care is somewhat similar to kojic acid, which can inhibit tyrosinase activity in vivo, thereby controlling the pigmentation of the skin. But because the value of the acid is extracted from plants, it is edible, so in the role of antioxidant and whitening when the sensitization rate is low, high safety, it is considered as an ideal alternative component of kojic acid. as early as the early 1995, phytic acid has been used as a skin whitening agent in clinical practice. In the process of melanin formation, it works by blocking the entry of iron and copper, this antioxidant effect is important for the skin and can help protect the skin from sun damage while lightening the dark complexion. The value of acid is used in all kinds of packaged food because of its characteristics in this regard, the seeds are not easy to decay because of the antioxidant effect of phytate, phytic acid is commonly used as a preservative in the food industry, the same mechanism is used to prevent food decay. The anti-oxidation and anti-free radical effect of phytic acid is due to the chelating property of phytic acid, because most oxidation processes in nature require metal ions as catalysts, which will produce highly active free radicals, after the complexation of iron ions, can reduce the generation of free radicals, but also slow down the oxidation reaction, and only calculate relatively stable. These effects have been concerned in the field of cosmetics, so the value acid component has been paid more and more attention in recent years. In addition, the value acid also has the effect of mild exfoliation. Compared with other acid components such as fruit acid, it will be much milder under the same PH condition. The acid binds to the calcium in the pores and softens it, Helps to make the pores temporarily smaller. Studies have also shown that phytic acid can reduce inflammation, so it is very suitable for people with sensitive skin or rosacea. |

Especially in the application of cyanide plating solution, the metal surface treatment with phytic acid or sodium phytate instead of sodium cyanide is very remarkable. A mineral chelating agent that combines with a mineral to form a mineral-phytate complex. The conversion coating can also be formed by complexing with metal ions bound on the surface of the magnesium alloy, so that the resistance of the magnesium alloy to corrosion can be improved. |
| production method | widely exists in nature, but hardly exists in a single free state. Generally, the complex form of calcium, magnesium or potassium double salt (calcium hexaphosphate magnesium) and protein is widely present in plants, and it is often found in seeds, grains, embryos, rice bran. There are many reports on the preparation of this product. Rice bran or wheat bran is used as raw material, after being soaked in dilute acid, it is filtered, neutralized and precipitated with lime and sodium hydroxide, and then acidified and exchanged with ion exchange resin, concentrated under reduced pressure, decolorized and filtered to obtain the finished product. In addition, it is also possible to use a method of removing metal ions by chemical synthesis of cyclohexanol and inorganic phosphoric acid, or by using calcium magnesium phytate as a raw material. It can also be extracted from corn activated sludge. extracted from rice bran or cottonseed cake by acid leaching and alkali precipitation. Calcium magnesium phytate was heated in 2% HCl and treated with cation exchange resin. The crushed rice bran was soaked in dilute hydrochloric acid with pH value of 2 at 50~60 ℃ for 4~6h, the filter residue was soaked for 2H after filtration, and the waste residue was filtered, l0h was allowed to stand, and the supernatant was aspirated; Appropriate amounts of Ca(OH)2 and Mg(OH)2 were added to the supernatant, and the pH value was adjusted from 3.4 to 7.0 with NaOH solution, after stirring for 15min, the mixture was allowed to stand for 2-3H; The supernatant was discarded, filtered, and the residue was sequentially washed with aqueous alkali solution with pH value of 7.5 and distilled water to obtain calcium magnesium phytate in a yield of 95%-98%. Calcium magnesium phytate is dissolved in dilute hydrochloric acid solution with pH value of 3, and then soaked and stirred at 75 ℃ for 1 h to maintain pH value of 3.5-4.5, so that calcium magnesium phytate dissolves and protein precipitates. Adding 1% of the weight of the supernatant diatomite, stirring and static Suction filtration to remove protein and other precipitates; The filtrate sequentially passed through strong acidic cation exchange resin and strong basic anion exchange resin to obtain dilute phytic acid solution; it is concentrated under reduced pressure at 75 ° C. To a content of 55% to 65%. Put the above phytic acid solution into a polyol solvent (such as ethylene glycol, propylene glycol or glycerin), and heat and reflux at 130~150 °c for 3~4H, the pH value of the hydrolysate is adjusted to 8~9 at I00 ℃ ± 10 ℃, and then the mixture is stirred for 1 h while standing for filtration. The filtrate is heated to 135 ℃ for dehydration, and then 3 times the amount of anhydrous ethanol is added, the crystallization product is precipitated by standing. |
