Discussion on the Development and Application Prospects of Compound Phosphates
Thread Content
Phosphorus is an important mineral element essential for the human body. The main sources of phosphorus intake for humans are natural foods or phosphate additives in foods, with phosphates being one of the natural components present in almost all foods. Phosphates are currently the most widely used food quality improvers in the world, and they are increasingly applied in various fields of processed foods, playing an important role in enhancing and improving food quality. Currently, single phosphate food additives are being gradually replaced by compound phosphate additives. Like other additives, quality improvers will inevitably move toward a blended format, that is, blended quality improvers composed of several types of quality improvers in a specific formula. These quality improvers have seen rapid development at home and abroad in recent years, and practice has proven them to be very convenient and effective. Composite phosphate quality improvers will open up broader prospects for promoting the use of phosphates in the food industry. The excellent properties of high-quality compound phosphates allow for a reduction in the use of carrageenan and starch in the same products, thereby improving the quality of meat products and reducing production costs. The key component of high-quality compound phosphates is phosphate, which has good solubility; a small amount of it is sufficient, allowing for reduced usage and minimizing the adverse effect of excessive phosphate on the taste of meat products. In terms of technical methods and application fields, composite phosphates are formed by physically mixing various monophosphate compounds, and their overall performance is superior to that of the individual monophosphates. At present, this technology is not yet developed in China, and the relevant products rely mainly on imports. This post was last edited by scst350 on 2009-4-7 11:11]
Phosphates are currently the most widely used food additives around the world, playing an important role in improving food quality, such as affecting the water retention, gel strength, and yield of meat products. Its beneficial effects on noodles in grain and oil products include the ability to develop new leavening agents, its impact on frozen dumplings, and its use in seafood processing. This article introduces the applications of compound phosphates in food and their mechanism of action. The use of phosphates in meat products In the processing of meat products, the addition of phosphates can increase the pH value of the meat ； Chelating metal ions in meat ； Increase the ionic strength of the meat ； Dissociated actomyosin. Phosphates are also widely used to improve muscle protein water retention and gel strength. Phosphates have a significant effect on the water retention of meat protein (protein extracted from meat). The use of phosphates in grain and oil products The benefits of phosphates for noodles lie mainly in their ability to enhance the strength of the gluten and reduce the amount of starch that leaches out ； Enhance the viscoelasticity of noodles ； Improve the surface smoothness of the noodles. The use of phosphates in the production of frozen steamed buns is primarily aimed at improving the texture and taste of these buns ； Increase the water-retention capacity of steamed buns, and reduce water loss during the processes of shaping, resting, and cooling after steaming ； Increase the fluffiness of steamed buns ； Reduce cracking of steamed buns after thawing ； It makes the steamed buns have more uniform air pockets, a finer texture, and a better taste. Compound phosphates also have a certain effect on frozen dumplings. Adding phosphates can prevent the color of the dumpling wrapper from darkening after thawing. The use of compound phosphates in seafood processing can effectively address the loss of flavor and nutritional components in seafood, while preventing and reducing oxidation ； It reduces physical discoloration and off-flavors, improves the water retention capacity of muscle tissue, enhances flavor, and increases water retention during thawing.
