How are monophosphates formed?

Sodium monophosphates are usually produced by neutralization of phosphoric acid with soda ash or caustic soda. The latter is predominantly used in Germany, while in the United States, the less expensive soda ash prevails. The basicity of sodium carbonate is insufficient for the formation of trisodium phosphate, so that caustic soda must be used in this step. The phosphates crystallize from the solutions as hydrates and are separated by centrifugation. Anhydrous salts are obtained by dehydration in rotary dryers or directly from the solutions by spray drying or in rotary kilns. Both thermal phosphoric acid and the cheaper wet phosphoric acid are used as starting materials. The very pure thermal phosphoric acid is generally used in the production of food-grade phosphates. /Sodium monophosphates/

What is the role of phosphate in the body?

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues.

What is sodium phosphate?

Sodium Phosphate is an inorganic compound used as a laxative, dietary supplement and for electrolyte-replacement purposes. Phosphate, a predominant intracellular anion, plays an important role in energy storage, osteoblastic and osteoclastic activities, regulating serum calcium concentrations, and numerous cellular phosphate -transfer reactions. Sodium phosphate increases fluidity of the intestinal contents by retention of water by osmotic forces, thereby indirectly inducing intestinal smooth muscle constriction. Sodium phosphate is also used in the renal excretion of hydrogen ions while promoting the reabsorption of sodium ions.

Applied with sponges or scrub brushes, TSP is an effective, heavy-duty cleaner for problem areas around the house that may be sooty, greasy, or dirty. Though bans on phosphates are in effect in many communities, TSP, where legal, is often favored by contractors and painters to ensure that the surface will be clean, dust-free, and able to take the paint. Phosphate-free substitutes to TSP are available.

What is TSP in poultry?

TSP is known for its surfactant properties which aid in preventing Campylobacter and Salmonella attachment to poultry. In addition TSP has the ability to remove some fat from the meat which indirectly aids in the removal of bacteria attached to the fat on the meat ( Sarjit and Dykes, 2015 ).

What is TSP used for?

Among the inorganic phosphates, trisodium phosphate (TSP) is a well-recognised antimicrobial used in poultry processing facilities. Trisodium phosphate is formed by neutralizing phosphoric acid with sodium hydroxide as follows: Na2 HPO 4 + NaOH → Na 3 PO 4 + H 2 O. Low reactivity of Na + and PO 43− ions which are produced due to the dissociation of TSP when mixed with water causes extremely low by-product formation. This inorganic phosphate is an alkaline sanitizer and is used between pH 10–12. Gram negative bacteria such as Campylobacter and Salmonella are more susceptible to alkaline sanitizers including TSP at this pH range than Gram positive bacteria due to the presence of the thin peptidoglycan layer (Capita et al., 2002; Dickson et al., 1994 ). TSP is known for its surfactant properties which aid in preventing Campylobacter and Salmonella attachment to poultry. In addition TSP has the ability to remove some fat from the meat which indirectly aids in the removal of bacteria attached to the fat on the meat ( Sarjit and Dykes, 2015 ). It is also able to remove the protective lipid layer on the meat enabling it to reach the entrapped pathogens thereby reducing the prevalence of these pathogens on meat ( Capita et al., 2002 ).

What is the purpose of TSP?

Trisodium phosphate (TSP) was developed in the US for the control of salmonella on poultry. TSP (Na3 PO 4) possibly works by removing a thin layer of fat from the carcass surface and in doing so removing the microorganisms attached to the surface ( Giese, 1992), it then causes rupture of the bacterial cell membrane.

How does TSP work?

As an antimicrobial, TSP removes attached bacteria from carcass surfaces by means of its surfactant properties and high alkalinity (pH about 12.0). In addition, TSP kills bacteria by disrupting the cell membrane and causing leakage of cellular material (Giese, 1993 ).

Which bacteria are more susceptible to alkaline sanitizer?

Gram negative bacteria such as Campylobacter and Salmonella are more susceptible to alkaline sanitizers including TSP at this pH range than Gram positive bacteria due to the presence of the thin peptidoglycan layer (Capita et al., 2002; Dickson et al., 1994 ).

Is trisodium phosphate a disinfectant?

Trisodium phosphate has been tested as a disinfectant for fresh produce by a few authors. Zhuang and Beuchat (1996) demonstrated complete inactivation of Salmonella Montevideo. Liao and Sapers (2000) observed a 1 log reduction on the surface when tomatoes were dipped in 15% trisodium phosphate for 15 s.

Does TSP kill microbials?

Although, TSP is effective in reducing microbial counts from poultry, there are some concerns about using the compound. In particular, the high pH can cause problems when the spray-application method is used prior to carcasses entering the chiller. The resultant increase in the alkalinity of the chill-water to pH 9.5–10.5 decreases the antimicrobial activity of added chlorine. Following treatment, any attempt to remove residual TSP by spray-washing the carcasses would only add to treatment cost and complexity. In addition, large amounts of phosphate in the wastewater represent an environmental issue. Finally, like many chemical treatments, the compatibility of phosphate compounds with processing equipment must be considered. Over time, phosphates can be corrosive to metal equipment, although less so than substances such as chlorine.
