Uses
SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents.
A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramic particles.
It is also used as a dispersing agent to break down clay and other soil types for soil texture assessment.
It is used as an active ingredient in toothpastes as an anti-staining and tartar prevention ingredient.
The energy drink NOS contains sodium hexametaphosphate.
Food additive
As a food additive, SHMP is used as an emulsifier. Artificial maple syrup, canned milk, cheese powders and dips, imitation cheese, whipped topping, packaged egg whites, roast beef, fish fillets, fruit jelly, frozen desserts, salad dressing, herring, breakfast cereal, ice cream, beer, and bottled drinks, among other foods, can contain SHMP.
Preparation
SHMP is prepared by heating monosodium orthophosphate to generate sodium acid pyrophosphate:
2 NaH2PO4 → Na2H2P2O7 + H2O
Subsequently, the pyrophosphate is heated to give the corresponding sodium hexametaphosphate:
3 Na2H2P2O7 → (NaPO3)6 + 3 H2O
followed by rapid cooling.
Reactions
SHMP hydrolyzes in aqueous solution, particularly under acidic conditions, to sodium trimetaphosphate and sodium orthophosphate.
History
Hexametaphosphoric acid was named (but misidentified) in 1849 by the German chemist Theodor Fleitmann.
By 1956, chromatographic analysis of hydrolysates of Graham’s salt (sodium polyphosphate) indicated the presence of cyclic anions containing more than four phosphate groups;[15] these findings were confirmed in 1961.
In 1963, the German chemists Erich Thilo and Ulrich Schülke succeeded in preparing sodium hexametaphosphate by heating anhydrous sodium trimetaphosphate.
Safety
Sodium phosphates are recognized to have low acute oral toxicity. SHMP concentrations not exceeding 10,000mg/l or mg/kg are considered protective levels by the EFSA and USFDA. Extreme concentrations of this salt may cause acute side effects from excessive blood serum concentrations of sodium, such as: “irregular pulse, bradycardia, and hypocalcemia.”

Abstract
Sodium hexametaphosphate (SHMP) is commonly used as an emulsifying salt (ES) in process cheese, although rarely as the sole ES. It appears that no published studies exist on the effect of SHMP concentration on the properties of process cheese when pH is kept constant; pH is well known to affect process cheese functionality. The detailed interactions between the added phosphate, casein (CN), and indigenous Ca phosphate are poorly understood. We studied the effect of the concentration of SHMP (0.25–2.75%) and holding time (0–20 min) on the textural and rheological properties of pasteurized process Cheddar cheese using a central composite rotatable design. All cheeses were adjusted to pH 5.6. The meltability of process cheese (as indicated by the decrease in loss tangent parameter from small amplitude oscillatory rheology, degree of flow, and melt area from the Schreiber test) decreased with an increase in the concentration of SHMP. Holding time also led to a slight reduction in meltability. Hardness of process cheese increased as the concentration of SHMP increased. Acid-base titration curves indicated that the buffering peak at pH 4.8, which is attributable to residual colloidal Ca phosphate, was shifted to lower pH values with increasing concentration of SHMP. The insoluble Ca and total and insoluble P contents increased as concentration of SHMP increased. The proportion of insoluble P as a percentage of total (indigenous and added) P decreased with an increase in ES concentration because of some of the (added) SHMP formed soluble salts. The results of this study suggest that SHMP chelated the residual colloidal Ca phosphate content and dispersed CN; the newly formed Ca-phosphate complex remained trapped within the process cheese matrix, probably by cross-linking CN. Increasing the concentration of SHMP helped to improve fat emulsification and CN dispersion during cooking, both of which probably helped to reinforce the structure of process cheese.

Introduction
Process cheese is made by grinding natural cheese and then heating the cheese in the presence of one or more Ca chelating salts (phosphate or citrates), often called emulsifying salts (ES). In the United States, the Code of Federal Regulations (Department of Health and Human Services, 2004) identifies 13 types of ES that can be used in process cheese manufacture, either singly or in combination, and allows for the addition of up to 3% (wt/wt; Kapoor and Metzger, 2008). These ES help disperse the insoluble CN in natural cheese curd, and it is these solubilized CN that can then act as emulsifiers around the liquid fat released during the heating and shearing of natural cheese. These ES function as ion exchangers, buffers, and Ca sequestrants and cause CN dispersion and peptization. Several reviews exist on the properties of the ES used for process cheese manufacture (Carić et al., 1985; Berger et al., 1998; Zehren and Nusbaum, 2000; Guinee et al., 2004).
Long-chain polyphosphates are commonly (but incorrectly) called hexametaphosphates. The real hexametaphosphates are ring forming and are not used in process cheese. Sodium hexametaphosphates (SHMP) have a wide range of uses in the food industry, including increasing the water binding properties of proteins in processed meats, protein precipitation for purification purposes, and prevention of protein sedimentation in sterilized milks (Molins, 1991). Sodium hexametaphosphates are often used in process cheese manufacture either singly or more commonly in a blend of several types of ES.

SHMP IN PAINTS AND COATINGS INDUSTRY:
With more and more brands in the paint industry, the competition in the market has become more and more fierce. The quality of products has become a breakthrough in the future paint industry and a guarantee for the preparation of coatings with good performance. In order to make the coatings disperse better, it is necessary to use technical grade sodium hexametaphosphate(SHMP) to disperse and improve the fluidity of the coatings.
In recent years, coatings have changed the traditional, single and conservative curing image, and then developed to personalized decorative and environmental protection products. Pure taste, full effect, formaldehyde resistance are still new words in coatings. With the continuous addition of bamboo charcoal, no addition and other “new members”, product varieties in the coatings market have gradually become more abundant. The effect of the paint is unchanged. In order to avoid the high viscosity and paste-like coating, which does not meet the requirements of brushing performance, the amount of sodium hexametaphosphate(SHMP) is determined according to the viscosity of the paint.
Sodium hexametaphosphate(SHMP) has a great influence on the dripping property of coatings.
The dripping property of coatings decreases rapidly with the increase of Technical grade sodium hexametaphosphate(SHMP) content.
Dripping property reflects the ability of coating to adhere to the surface of die, but unlike viscosity, dripping property is an important index in the painting process.
The lower the dripping property, the better the adhesion of the coating to the mould, but the dripping property can not be too low.
The dripping property and leveling property of the coating are important performance indicators in the painting process.
The lower the dripping property, the worse the leveling property of the coating and the serious marks of the coating appear in the painting process.
Beverage
SHMP is used in a variety of beverage products. It extends shelf life, enhances flavor, and also improves clarity and prevents turbidity, such as in fruit juices and carbonated beverages. It can also stabilize the protein and enhance flavor in a protein drink.
Canned food
SHMP stabilizes natural pigments in canned beans, fruits and vegetables, and therefore protect its color. Also, it can emulsify fat in canned meat, resulting in maintaining uniform texture.
Food grade SHMP can also be used with other sodium phosphates to retain moisture, enhance flavor, and increase shelf life in the processing of meats, cheese, dairy products, seafood, and poultry.
Sodium hexametaphosphate (SHMP) is commonly used as an emulsifying salt (ES) in process cheese, although rarely as the sole ES. It appears that no published studies exist on the effect of SHMP concentration on the properties of process cheese when pH is kept constant; pH is well known to affect process cheese functionality.

Chemical formula
Sodium metaphosphate is to describe polyphosphate with four or more phosphate units. Here SHMP has six phosphate units with the chemical formula (NaPO3)6.
Preparation
SHMP is prepared by heating monosodium orthophosphate to generate sodium acid pyrophosphate:
2 NaH2PO4 → Na2H2P2O7 + H2O
Subsequently, the pyrophosphate is heated to give the corresponding sodium hexametaphosphate:
3 Na2H2P2O7 → (NaPO3)6 + 3 H2O
followed by rapid cooling.
Reactions
SHMP hydrolyzes in aqueous solution, particularly under acidic conditions, to sodium trimetaphosphate and sodium orthophosphate.[13]

PERFORMANCE COMPARISION OF PHOSPHATES:
Sodium hexametaphosphate (SHMP) generally performs very well at close-to-neutral pH ranges, while tetrasodium pyrophosphate (TSPP) and sodium tripolyphosphate (STPP) work best under alkaline conditions.
Monosodium phosphate (MSP) is often used together with SHMP for more acidic pH environments.
The so-called threshold effect refers to the ability of some phosphate compounds to inhibit the formation of carbonate or sulfate scales well below the amount that would be required for a stoichimetric 1:1 combination with the metal ions.
This apparently results by the phosphate interfering with early crystal growth.
In the case of SHMP, only 2-4 ppm is all that is required to inhibit scale formation in water with relatively high calcium levels.
Chemical Properties
The sodium polyphosphates class consists of several amorphous, water soluble polyphosphates composed of linear chains of metaphosphate units, (NaPO3)x where x ≥ 2, terminated by Na2PO4- groups. They are usually identified by their Na2O/ P2O5 ratio or their P2O5 content.
The Na2O/P2O5 ratios vary from about 1.3 for sodium tetrapolyphosphate, where x = approximately 4; through about 1.1 for Graham’s salt, commonly called sodium hexametaphosphate, where x = 13 to 18; to about 1.0 for the higher molecular weight sodium polyphosphates, where x = 20 to 100 or more.
The pH of their solution varies from about 3 to 9. For additional details of description, refer to Burdock (1997).
Uses
Sodium Hexametaphosphate is a sequestrant and moisture binder that is very soluble in water but dissolves slowly. solutions have a ph of 7.0. it permits peanuts to be salted in the shell by making it possible for the salt brine to penetrate the peanuts. in canned peas and lima beans, it functions as a tenderizer when added to the water used to soak or scald the vegetables prior to canning. it improves whipping properties in whipping proteins.

This is an inorganic salt.
Preparation
Sodium hexametaphosphate is prepared by heating monosodium phosphate (NaH2PO4) rapidly to a clear melt, which occurs slightly above 625°C. Rapid chilling of this melt produces a very soluble glass, which is then crushed or milled.
Agricultural Uses
Sodium metaphosphate is the salt of metaphosphoric acid having a molecular formula (NaPO3)n, where n ranges from 3 to 10 (for cyclic molecules) or may be much larger (for polymers).
Cyclic molecules have alternate phosphorus and oxygen atoms in the rings and start with trimetaphosphate (NaPO3)3 to at least decametaphosphate.
Sodium hexametaphosphate may be a polymer where n is between 10 and 20.
Vitreous sodium phosphates have a Na2O:P2O5 ratio near unity and are called Graham’s salts.
The average number of phosphorus atoms in these vitreous glasses ranges from 25 to infinity.
Industrial uses
Sodium hexametaphosphate (SHMP) or water glass Na6P6O18 is basically the salt of metaphosphoric acid. SHMP is difficult to dissolve.
By mixing SHMP for 1-3 h, a solution of 8-10% can be obtained.
The pH of this solution is about 5. Because of a weak acid reaction, the SHMP reacts with cations of bivalent metals forming Na2MeP6O18 or Na4MeP6O18.
In the presence of oxygen, SHMP slowly decomposes into pyrophosphate and orthophosphate.

Merkezi bir kompozit döndürülebilir tasarm kullanarak pastörize ilem Cheddar peynirinin dokusal ve reolojik özellikleri üzerinde SHMP (% 0,25–2,75) ve bekletme süresinin (0–20 dakika) etkisini inceledik. Tüm peynirler pH 5.6’ya ayarland. lem peynirinin eritilebilirlii (Schreiber testinden küçük genlikli osilatör reolojisinden kayp teet parametresindeki azalma, ak derecesi ve eriyik alan ile gösterildii gibi) SHMP konsantrasyonundaki bir artla azald. Bekletme süresi ayrca eritilebilirlikte hafif bir azalmaya yol açt. SHMP konsantrasyonu arttkça proses peynirinin sertlii artmtr. Asit-baz titrasyon erileri, tortusal koloidal Ca fosfata atfedilebilen pH 4.8’deki tamponlama zirvesinin, artan SHMP konsantrasyonu ile daha düük pH deerlerine kaydrldn gösterdi. SHMP konsantrasyonu arttkça çözünmeyen Ca ve toplam ve çözünmeyen P içerikleri artmtr. Toplam (yerli ve eklenen) P yüzdesi olarak çözünmeyen P oran, baz (eklenen) SHMP’nin oluturduu çözünür tuzlardan dolay ES konsantrasyonunda bir artla azald. Bu çalmann sonuçlar, SHMP’nin artk koloidal Ca fosfat içeriini elatladn ve CN’yi dattn göstermektedir; yeni oluan Ca-fosfat kompleksi, muhtemelen CN’nin çapraz balanmasyla, ilem peynir matrisi içinde skm olarak kald. SHMP konsantrasyonunun arttrlmas, piirme srasnda ya emülsifikasyonunun ve CN dalmnn iyiletirilmesine yardmc oldu, her ikisi de muhtemelen ilem peynirinin yapsn güçlendirmeye yardmc oldu.

pastörize ilem Cheddar peyniri emülsifiye edici saltrheoloji doku
Giri
lem peyniri, doal peynirin öütülmesi ve ardndan peynirin, genellikle emülsifiye edici tuzlar (ES) olarak adlandrlan bir veya daha fazla Ca elatlama tuzu (fosfat veya sitrat) varlnda stlmasyla yaplr. Amerika Birleik Devletleri’nde, Federal Düzenlemeler Yasas (Salk ve nsan Hizmetleri Bakanl, 2004), tek bana veya kombinasyon halinde peynir üretiminde kullanlabilecek 13 ES türünü tanmlar ve% 3’e kadar eklenmesine izin verir (wt / wt; Kapoor ve Metzger, 2008). Bu ES, çözünmeyen CN’nin doal peynir peyniri içinde dalmasna yardmc olur ve daha sonra doal peynirin stlmas ve kesilmesi srasnda salnan sv ya etrafnda emülgatör görevi görebilen bu çözündürülmü CN’dir. Bu ES, iyon deitiriciler, tamponlar ve Ca tutucu olarak ilev görür ve CN dispersiyonuna ve peptizasyona neden olur. Proses peyniri üretiminde kullanlan ES’nin özellikleri hakknda birkaç inceleme bulunmaktadr (Carić ve dierleri, 1985; Berger ve dierleri, 1998; Zehren ve Nusbaum, 2000; Guinee ve dierleri, 2004).
Uzun zincirli polifosfatlar genellikle (ancak yanl bir ekilde) heksametafosfatlar olarak adlandrlr. Gerçek heksametafosfatlar halka oluturur ve ilem peynirinde kullanlmaz. Sodyum heksametafosfatlar (SHMP), ilenmi etlerde proteinlerin su balama özelliklerinin artrlmas, saflatrma amacyla protein çökeltmesi ve sterilize sütlerde protein çökelmesinin önlenmesi dahil olmak üzere gda endüstrisinde geni bir kullanm alanna sahiptir (Molins, 1991). Sodyum heksametafosfatlar genellikle tek bana veya daha yaygn olarak çeitli ES türlerinin bir karmnda peynir üretiminde kullanlr.
