Food grade Tetrasodium pyrophosphate exists as two forms, and follows the corresponding chemical formula:

Tetrasodium pyrophosphate Anhydrous: Na4P2O7
Tetrasodium pyrophosphate Decahydrate: Na4P2O7 · 10H2O

Uses:

Tetrasodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive.
Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer.

In toothpaste and dental floss, tetrasodium pyrophosphate acts as a tartar control agent, serving to remove calcium and magnesium from saliva and thus preventing them from being deposited on teeth.
Tetrasodium pyrophosphate is used in commercial dental rinses before brushing to aid in plaque reduction.

Tetrasodium pyrophosphate is sometimes used in household detergents to prevent similar deposition on clothing, but due to its phosphate content it causes eutrophication of water, promoting algae growth.

The specific use petitioned is as a pH buffer and dough conditioner for use in organic meat alternative products.
Cereal and baked goods account for the greatest food use of phosphate additives.
The principal food uses for tetrasodium pyrophosphate are as an emulsifier, buffer, nutrient, dietary supplement, sequestrant, and texturizer.

Tetrasodium Pyrophosphate,(TSPP) Granular & Powder is an anhydrous, white, crystalline material in powder form.
Tetrasodium pyrophosphate is used as a dispersing agent, sequestrant, buffering agent, protein modifier, and coagulant.

Tetrasodium pyrophosphate is used to modify the proteins enabling them to retain moisture during storage, thawing, and cooking.

Tetrasodium pyrophosphate is added to improve whipping efficiency and improve foam stability.
Granular Tetrasodium pyrophosphate helps to buffer the pH of the processed cheese and interacts with milk proteins to promote emulsification.
Tetrasodium pyrophosphate sequesters iron in potato products to prevent after-cooking blackening and to stabilize color.
To maintain fat dispersion in an ice cream/dessert mix, Tetrasodium pyrophosphate may be added so "churning" will not form lumps of butter during freezing.

With the properties of chelating metal ions, increasing protein water holding capacity, PH buffering, stabilization, emulsification, casein thickening and ect, tetrasodium pyrophosphate is widely used in food to improve the gel strength and the tenderness of meat products/analogs.

Also, Tetrasodium pyrophosphate is used with other phosphates (e.g. sodium hexametaphosphate, sodium acid pyrophosphate) in seafood to increase the water retention.

Food
Food grade Tetrasodium pyrophosphate is mainly used in following two functions:

A buffering agent: with the PH value from 9.8 to 10.8 (1% solution), TSPP can be used as an alkaline to adjust pH in processed food, pudding and etc.
A calcium sequestrant: TSPP can remove naturally occurring calcium ions from proteins and crosslink with proteins, which results in accelerating protein gelation, improving texture (mouthfeel) and reducing cooking loss in meat analog production (e.g. soy protein).

Following food list may contain TSPP:

-Meat analogs, such as soy or wheat based food, with the appearance, flavor and mouth-feel the same with meat but not made from meat.
-Marshmallows
-Pudding
-Cheese
-Ice cream
-Milk protein products
-Tuna
-Toothpaste

Orally the main purpose of TSPP is to prevent the formation of calculus by reducing the deposition of calcium and magnesium on teeth.
Thus it is commonly used as the anticalculus component of many tartar-control toothpastes and mouth rinse.
Disodium pyrophosphate also has the same function.

Applications :

• Tetra Sodium pyrophosphate is used as a buffering agent, also as an emulsifier and as a dispersing agent
• Tetra Sodium Pyrophosphate also used as a thickening agent and also often used as a food additive
• Tetrasodium pyrophosphate is used in common baking powders and also in toothpaste and dental floss as a tartar control
• Sometimes Tetrasodium pyrophosphate is also used in household detergents

Production
Tetrasodium pyrophosphate is produced by the reaction of furnace-grade phosphoric acid with sodium carbonate to form disodium phosphate, which is then heated to 450 °C to form tetrasodium pyrophosphate:

2 Na2HPO4 → Na4P2O7 + H2O

Physical Description

Tetrasodium pyrophosphate appears as odorless, white powder or granules.
mp: 995 °C.
Density: 2.53 g/cm3.
Solubility in water: 3.16 g/100 mL (cold water); 40.26 g/100 mL boiling water.
Used as a wool de-fatting agent, in bleaching operations, as a food additive.
The related substance tetrasodium pyrophosphate decahydrate (Na4P2O7*10H2O) occurs as colorless transparent crystals.
Loses its water when heated to 93.8 °C.

Action:
Phosphates in general interact with proteins, such as casein, to function as emulsifiers and prevent the separation of both fat and water in cheese.
Casein is precipitated by pyrophosphates to form thick gels.
This is believed to be the result of the negative ionic charge of pyrophosphate anions reacting with the positively charged cations in casein.
Pyrophosphates are good sequestrants for copper and iron, which often catalyze oxidation in fruits and vegetables.
One source notes considerable debate about the mechanisms of phosphate functionality, with reference to water holding capacity of meat and fish.
The addition of phosphates to muscle food homogenates, raw and cooked meats, in sausages, hams, poultry, and seafood will decrease the amount of drip loss, enhance waterbinding and water holding capacity resulting in enhanced sensory characteristics.

Combinations:
Tetrasodium pyrophosphate is combined with calcium phosphates as leavening agents.
Tetrasodium pyrophosphate has a synergistic effect on various foaming agents, such as alkyl polycarboxylates and triethyl citrate.
Other salts, such as sodium chloride, can have a synergistic effect on water-holding capacity of sodium phosphates

Historic Use:
The interaction of shorter chain polyphosphates—including pyrophosphates—with proteins was first known in 1916.
Industrial manufacturing of pyrophosphates occurred as early as the 1920s.
Commercial application of polyphosphates for preparing vegetable protein-polyphosphate compounds in food processing appears to date back to the late 1940s.

Uses:

-Buffering Agent

-Emulsifier

-Dispersing Agent

-Thickening Agent

-Tartar Control Agent

-Toothpaste
