Sodium acid pyrophosphate (also known as Sodium Acid Pyrophosphate) is a common food additive with a variety of functions and is widely used in the food industry. The following are the main applications of sodium acid pyrophosphate in food:
Antioxidants effect
Sodium acid pyrophosphate can react with water and oxygen to form oligomers, which can protect food from oxidative damage and prolong the shelf life of food.
Thickeners effect
Sodium acid pyrophosphate can increase the viscosity of the food, improve the taste of the food, make the food more viscous and extend the shelf life of the food.
Puffing effect
Sodium pyrophosphate can promote the production of gas inside the food, make the food become more fluffy, commonly used in cakes, bread and other baked goods.
Antiseptic effect
Sodium pyrophosphate can inhibit the growth of microorganisms by changing the pH value of food, so as to extend the shelf life of food.
Moisturising effect
Sodium Acid Pyrophosphate can reduce the surface tension of food, making it easier to process and pack.
Stabilisation
Sodium Acid Pyrophosphate has a certain antioxidant effect, can inhibit lipid peroxidation reaction, so as to achieve the effect of food stabilisation.
Foaming
Sodium Acid Pyrophosphate can denature the proteins in the food, thus fermentation and make the food taste more delicious.
Sodium acid pyrophosphate can make the fatty acid, glycerides and other substances in raw materials undergo emulsification reaction in the process of food processing, which is beneficial to the digestion and absorption of food after processing.
Specific effect on steamed potatoes
The specific effects of sodium acid pyrophosphate in steamed potatoes include preventing discolouration and maintaining the colour and texture of potatoes, as well as improving the nutritional value of potatoes.
Cautions.
Despite the many benefits of sodium acid pyrophosphate in food, excessive intake may lead to unpleasant symptoms such as diarrhoea and nausea. Therefore, strict dosage control and adherence to relevant standards are required for its use.
Conclusion
As a multifunctional Food additive, sodium acid pyrophosphate plays an important role in the food industry, enhancing the quality and safety of food in many ways, from antioxidant, thickening to preservation. However, consumers still need to pay attention to the principle of moderation when choosing foods to ensure a healthy diet.
