Trisodium phosphate is an inorganic compound that is easily soluble in water and is regularly used as a food additive, detergent, lubricant, and other cleaning agents. Although its application in consumer products has been accepted and popular, its application in food has been more questioned.

What is trisodium phosphate

The chemical formula of trisodium phosphate is Na3PO4. It is an inorganic compound that is generally present in the form of white powder or crystal. It is a universal cleaner; because it can easily be mixed with warm water to effectively clean oil, rust, smoke, and other difficult debris. You will also find sodium variety of foods trisodium phosphate. It is alkaline. Therefore, it is used to reduce the acidity found in some foods.

Special features of trisodium phosphate

  • Trisodium phosphate is colorless to white needle-like crystal or crystalline powder.
  • The melting point of Trisodium phosphate is dodecahydrate 73.4 °C.
  • Trisodium phosphate is soluble in water, and its aqueous solution is strongly alkaline.
  • It is insoluble in ethanol and carbon disulfide.
  • It is one of the vital product series of the phosphate industry.
  • Trisodium phosphate is widespread uses in new sectors such as agriculture, animal husbandry, petroleum, papermaking, detergent, ceramics, and other fields due to its unique properties.

Nature of trisodium phosphate

It is prone to deliquescence and weathering in dry air. And it generates sodium dihydrogen phosphate and sodium bicarbonate. Almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide in water.

  • Trisodium phosphate heated up to 55 ~ 65 ° C, it becomes decahydrate.
  • It’s heated up to 60 ~ 100 ° C, and it becomes hexahydrate.
  • Heated above 100 ° C, it becomes become monohydrate.
  • And it’s heated up to 212 ° C or more, and it becomes anhydrous.
  • The pH value of a 1% aqueous solution is 11.5 ~ 12.1.

Trisodium phosphate in cereals

Trisodium phosphate uses in the food industry 1

One of the main areas of contention in this debate is phosphorus, such compounds included in the breakfast cereal. It is often used as an ingredient in popular breakfast foods, which are often highly processed.

However, many big companies, such as General Mills, adding trisodium phosphate in cereals to reduce costs acidity change the color of the grain. The FDA notes that this compound is generally safe when taken orally in small doses. It is recommended that the daily intake should not exceed 70 mg. The intake of most cereals is much lower than this total.

In other words, many consumers are concerned about the presence of this compound because it is also present in paint thinners and industrial bleaching products. Many organic and independent grain producers have stopped using this phosphorus compound as a preservative or additive in their products. If you are worried about its safety, you may want to avoid products that use this additive.

Trisodium phosphate in food

In addition to cereals, you’ll also find trisodium phosphate inside the food in many processed and pre-packaged foods, such as the artificial, natural, and clinical aspects.

Most organic brands will not include phosphorus-derived inorganic compounds. Therefore, if you are careful about the products you buy, it should be easy to avoid this in your diet.

However, this phosphate is not only food. It is also present in some species, toothpaste, mouthwash, baking soda, cosmetics, and is certain drugs.

The main uses of trisodium phosphate

You will find tri-sodium phosphate all around.

  1. It is a popular cleaner.
  2. It is found in lubricants, detergents and degreasing agents.
  3. It is a food additive that can be found in various grains and other acidic foods.
  4. It is an inorganic form and is usually added to highly processed foods.
  5. It can also help certain foods increase, balance pH, retain moisture, protect flavor, and improve texture.

Applications of trisodium phosphate in the food industry

  1. Milk and dairy products, cream, emulsified products.
  2. Frozen drinks. (except edible ice).
  3. Canned vegetables.
  4. Cooked nuts and seeds (fried nuts and seeds only).
  5. Cocoa products.
  6. Chocolate and chocolate products.
  7. Confectionery.
  8. Wheat flour and Its products.
  9. Raw and wet pasta products (such as noodles, dumpling crusts, braised clams).
  10. Batters. (such as batters for fish and poultry meat).
  11. Ready-to-eat cereals (including rolled oats or oatmeal).
  12. Prepared meat products.
  13. Cooked meat products.
  14. Frozen aquatic products.
  15. Thermally coagulated egg products. (such as egg yolk, pine egg sausage).
  16. Beverage (Except packaged drinking water).
  17. Rice flour (including dumplings).
  18. Cereals and Starch desserts (such as rice puddings, cassava puddings, canned cereals only).
  19. Pre-made aquatic products (semi-finished products).
  20. Canned aquatic products
  21. Compound seasoning
  22. Other solid compound seasonings (only for convenient wet noodle seasoning package)
  23. Oils or oil products (only fat-based powders)
  24. Processed cheese
  25. For canned cereals and other cereal products
Trisodium phosphate uses in the food industry 2

Why add trisodium phosphate to food

Trisodium phosphate helps retain moisture during food storage and cooking. It also helps the cheese to maintain its shape and melt evenly.

In the case of cake mixes and other bread mixes, it can be used as a leavening agent to keep food “fluffy.” In addition, it is sometimes used as a thickener for packaged foods (such as mashed potatoes) to prevent the color change of soda water.

Because of its specificity, trisodium phosphate is included in toothpaste and mouthwashes antimicrobials impact.

Because of its strong alkalinity, you will also find that it is an ingredient that reduces the acidity of the food.

Similarly, like cereals, the amount of this phosphorus compound in most foods is also minimal and can be ignored. However, if your diet contains many processed foods, your total daily intake may exceed the FDA’s safety recommendations.

The side effects of trisodium phosphate

When consumed in high quantities, as found in cleaning products, trisodium phosphate is very dangerous.

It is associated with higher calcium deposition in the body, kidney stones, cancer, and even death. For those with kidney disease, overeating food containing such a phosphate compound is very dangerous.

It will stimulate the stomach and gastric intestinal reduce the amount of lactic acid in the muscles.

This compound is often found in dishwashing liquid and washing powder and was not found to be harmful to the environment until 2011. However, CDC compounds such as hazardous substances and may cause abdominal pain, shock, or crash.

The side effects are much greater than those found in regular foods.

However, many people dispute its existence in any food. In addition, many ongoing studies are exploring the potential adverse effects of trisodium phosphate. But at present, it is still legally permitted in the United States and elsewhere and is included in many popular consumer foods.
