Food additive E339 or sodium phosphates is a mixture of aluminum and sodium salts of phosphoric acid which is the mineral form of phosphorus. Its use as a food additive started during World War I in Germany. Nowadays it is used worldwide as an emulsifier and thickening agent in products like cheese, ice cream, fermented sausages, canned products, and desserts.

What is sodium phosphate?


Sodium phosphate is a compound with the chemical formula NaPO3. It is the salt of sodium and phosphate. It is a colorless solid, but impure samples can appear white because of impurities.

Sodium phosphate exists in both anhydrous (dry) and monohydrate (hydrated) forms. The monohydrate form is more common, but the anhydrous form is used industrially as a flame retardant and fire suppressant.

Sodium phosphate is used in many food products such as baked goods, cereals, and processed meats to prevent spoilage by controlling pH levels. It is also used as a firming agent in canned foods and as a preservative in soft drinks.

What is sodium phosphate used for?


Sodium phosphate is a salt that is used in various food products, as well as household cleaning products. It has many benefits and uses, but it can also be harmful when taken in large doses.

The main use of this ingredient is to add flavor to food. It can also be used as a preservative and to add color to foods. Sodium phosphate may also be added to drinks, especially sports drinks and soft drinks, as well as candy products such as chocolate bars or gummies. This ingredient is often found in canned meats and fish because it helps preserve the flavor of these foods longer than fresh products would last on the shelf.

Sodium phosphate can also be used in personal care items such as shampoos and body wash products that contain moisturizers or conditioners. This ingredient can help hold onto moisture in your skin for longer periods of time than would normally be possible without using it.

Sodium phosphate can be toxic when taken in large doses over a long period of time. People who work with this substance frequently should wear protective gear including gloves and goggles while handling it so they don’t accidentally ingest any while working with it on their hands or face during production processes. People who consume too much sodium phosphate over time.

What is sodium phosphate in food?


The main use of sodium phosphate is as a food additive. It is used as an emulsifier, a preservative and a stabilizer in many food products. Sodium phosphate also serves as a buffering agent for acidity control, especially in canned foods.

Sodium phosphate is used in meat products and processed meats like hot dogs and luncheon meats. It can be found in ketchup, salad dressing and canned fish products like tuna or salmon. In addition to being an ingredient on the label, sodium phosphate can be listed as phosphoric acid esters of mono- and di-glycerides and fatty acids (E-number E452).

Sodium phosphate is also used in baked goods like crackers and cookies, as well as cereals, which means there’s no way to avoid this additive if you eat packaged foods regularly.

How is sodium phosphate made?


The manufacture of sodium phosphate is a complex process that requires several steps. The first step is the preparation of phosphoric acid, which can be done in two ways. Phosphoric acid can be produced by the reaction of phosphorous pentoxide with potassium hydroxide, or by reacting ammonium phosphate with sulfuric acid.

The next step involves dissolving sodium carbonate in water and adding phosphoric acid to the solution until all of the sodium carbonate has been neutralized. The resulting solution contains sodium bicarbonate and sodium phosphate. The solution must then be heated until it evaporates, leaving behind a solid cake containing sodium phosphate and other compounds.

Finally, this cake is ground into a fine powder and dried to remove excess moisture from it before packaging it for sale to consumers.

sodium phosphate structure


Sodium phosphate is an ingredient in many processed foods and drinks, but it’s not something you should try to avoid all together. It can be found in foods like breads, cereals, soups, sauces and meat products. Most people don’t need to worry about consuming too much of this ingredient because most foods don’t contain high amounts of sodium phosphate anyway.

There are some people who should avoid eating sodium phosphate altogether though, such as those who have kidney problems or those who are taking certain medications like diuretics which increase the amount of urine produced by the body – this can cause excess sodium phosphate to build up in the body and cause damage to organs like the liver or kidneys. Other groups of people who should avoid eating too much sodium phosphate include those with high blood pressure or heart disease

Almost without side effects, they have been approved for use as food additives by the Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

What is the application of sodium phosphate?


Sodium phosphate is a compound used as a food additive and in many other applications. It is most commonly used to improve the texture of processed foods, and it also helps preserve them by preventing microbial growth. Sodium phosphate is also used as an ingredient in many personal care products, such as toothpaste and mouthwash.

There are a variety of functions that sodium phosphates serve in food, including the following:

General sequestrant

The product inhibits the formation of metal ions (e.g. Cu2+ and Fe2+) and thus prevents, discoloration, oxidation, and decomposition of vitamin C, ultimately prolonging the shelf life of the food, reducing the cooking time, and so on.

Chelating calcium (Ca2+)

Proteins retain water better when pyrophosphates combine with them and remove calcium ions from them.

PH buffering

In food, adjust the pH.

Emulsifier

This increases the viscosity of the product, prevents the separation of protein and fat, and improves the mouthfeel of the product. In cheeses that have been processed, for example.

Retaining moisture

Frozen seafood and poultry products (e.g. fish or shrimp) are enriched with polyphosphates to prevent protein denaturation and maintain water retention.

Leavening acid

A combination of sodium carbonate and urea is used to increase the volume of a loaf of bread by releasing CO2.

Industrial uses

Chelating metal ions is commonly used in industrial applications, such as water treatment and detergents.

Feed

Phosphorus sulfate is an inorganic feed phosphate (IFP), which is a source of mineral phosphorus that can be assimilated by animals. Phosphorus is vital nutrition in animal feed.

A mineral is not only a mineral that can be found in the bones and teeth of animals, but it is also an essential component of cell metabolism and the blood flow in animals, two things that are indispensable for growth, fertility, and the development of bones in animals if they are to grow and develop properly.

Some IFPs are used to retain moisture or make the feed fresh, and some of the IFPs are sodium phosphates; however, calcium phosphates have long been the most commonly used, but sodium phosphates are also being used.

What are the types of sodium phosphates?


There are several different types of sodium phosphates.

The most common is sodium tripolyphosphate, which is also known as STPP. This is a white powder that dissolves in water and can be used as an absorbent or thickener in many products. Other common forms include:

Monosodium phosphate (MSP) – A white powder that dissolves easily in water, MSP is often used in foods as a leavening agent for baked goods. It can also be used to treat drinking water, as well as in cleaning products such as laundry detergents.

Disodium phosphate (DSP) – This salt has been used since the early 20th century to treat water by removing phosphates from it so they don’t build up in the environment. It’s also added to some toothpastes and mouthwashes to help prevent cavities and reduce plaque buildup on teeth.

Trisodium phosphate (TSP) – A yellowish powder that dissolves easily in water, TSP is often found in cleaners for floors and walls because it removes grease and grime easily without irritating skin or eyes like ammonia does

What does sodium phosphate do to your body?


Sodium phosphate is a salt that can be used as a food additive, a mineral supplement and in water treatment. It’s a common ingredient in processed foods, including baked goods and canned vegetables. The body breaks down sodium phosphate into sodium and phosphate ions, which are then absorbed into the bloodstream. Sodium phosphate is also known as Na2HPO4 or Disodium hydrogen phosphate dihydrate.

Phosphorus is an essential mineral that plays a key role in many body functions, including the formation of DNA and RNA, cell growth, and bone maintenance. Phosphorus deficiency can cause muscle cramps, weakness, and fatigue. While most healthy adults don’t need extra phosphorus because they get enough from their daily diet, some people may need additional phosphorus if they have kidney disease or diabetes mellitus (sugar diabetes). High levels of phosphorus in the blood can lead to calcification of soft tissues such as the kidneys, heart valves, or joints — a condition called renal osteodystrophy.

Sodium phosphate has been used for decades to treat constipation because it stimulates bowel movements by drawing fluid into your intestines from other parts of your body. In addition, sodium phosphate works as an emulsifier — it helps oil-based ingredients mix with water-based ingredients in dairy products and ice cream.

What are the side effects of sodium phosphate?


Sodium phosphate is a mineral that occurs naturally in the body. It is also added to processed foods, such as canned vegetables and soups, to prevent them from tasting bitter. Sodium phosphate is used to treat high levels of calcium in the blood (hypercalcemia). It works by decreasing the absorption of calcium into the bloodstream.

Side effects are infrequent with sodium phosphate. However, they can occur and may include:

  • digestive problems, such as constipation, diarrhea or indigestion
  • diarrhea
  • nausea and vomiting
  • vomiting blood or having blood in your stool
  • headaches and dizziness
  • joint pain or stiffness.

Where to buy sodium phosphate?


You can purchase sodium phosphate from your local pharmacy or supermarket. It is also available in bulk and wholesale form, which makes it easier to get large quantities of the compound at a cheaper price. You can also find sodium phosphate on Amazon, eBay, and other online retailers.

Frequently Asked Question


Is sodium phosphate natural?

Difference between sodium phosphate monobasic and dibasic


Sodium phosphate monobasic and dibasic are two types of sodium phosphate. Both are salts, but they have different compositions and properties.

Sodium phosphate monobasic is used as a food additive to improve texture, flavor, and consistency in foods such as ice cream, salad dressing, and cheese spreads. It is also used in toothpaste, mouthwashes, and antacids to help bind the active ingredients to the teeth’s surface or stomach lining.

Sodium phosphate dibasic is used as an emulsifier in baked goods such as cakes and pastries to keep them from separating into layers during cooking. It also helps maintain moisture levels within a product so that it doesn’t dry out too quickly after being baked or cooked.

Conclusion


With this knowledge, you are now aware of the production, uses, types, and uses of sodium phosphates. They can control PH value, as well as control yeast activity, baking soda, baking powder, or salt content. In addition to these functions, they may also enhance flavors in food products. Sodium phosphate and sodium acid pyrophosphate are banned as food additives in Australia, Brazil, Canada, and the European Union.
