ACIDITY REGULATOR
Acidity regulators, or pH control agents, are food additives added to change or maintain pH (acidity or basicity). They can be organic or mineral acids, bases, neutralizing agents, or buffering agents.
Acidity regulators are indicated by their E number, such as E260 (acetic acid), or simply listed as “food acid”.
Commonly used acidity regulators are citric, acetic and lactic acids.
ACIDITY REGULATORS
lactic acid
adipic acid
Description: the organic compound with the formula (CH2)4(COOH)2. From the industrial perspective, it is the most important dicarboxylic acid: About 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon.
monosodium fumarate
Description: Buffering agent, flavoring agent, oxidation resistance auxiliaries. Used in producing wine, cold drink, sweet products, canned fruit, jam, jelly, etc.
fumaric acid
Description: the chemical compound with the formula HO2CCH=CHCO2H. This white crystalline compound is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid.
malic acid
Description: an organic compound with the formula HO2CCH2CHOHCO2H. It is a dicarboxylic acid that is made by all living organisms, contributes to the pleasantly sour taste of fruits, and is used as a food additive.
citric acid
Description: a weak organic acid. It is a natural preservative/conservative and is also used to add an acidic, or sour, taste to foods and soft drinks.
metatartaric acid
Description: a white crystalline diprotic organic acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in wine.
tartaric acid
Description: a white crystalline diprotic organic acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in wine.
hydrochoric acid
Description: Hydrochloric acid is a clear, colourless solution of hydrogen chloride (HCl) in water. It is a highly corrosive, strong mineral acid with many industrial uses. Hydrochloric acid is found naturally in gastric acid.
acetic acid
Description: an organic compound with the chemical formula CH3CO2H (also written as CH3COOH or C2H4O2). It is a colourless liquid that when undiluted is also called glacial acetic acid.
sodium sesquicarbonate
Description: Sodium sesquicarbonate (Systematic name trisodium hydrogendicarbonate) Na3H(CO3)2 is a double salt of sodium bicarbonate and sodium carbonate, and has a needle-like crystal structure.
sodium carbonate
Description: Sodium carbonate (also known as washing soda or soda ash), Na2CO3 is a sodium salt of carbonic acid. It most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate.
potassium carbonate
Description: Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in alcohol), which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide’s absorbent reaction with carbon dioxide.
potassium hydrogen carbonate
Description: Potassium bicarbonate (also known as potassium hydrogen carbonate or potassium acid carbonate) is a colorless, odorless, slightly basic, salty substance.
potassium hydroxide
Description: Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash. Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base.
calcium hydroxide
calcium lactate
sodium dihydrogen citrate
trisodium citrate
Description: Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as sodium citrate, though sodium citrate can refer to any of the three sodium salts of citric acid.
tripotassium citrate
calcium hydrogen phosphate
sodium tripolyphosphate
sodium polyphosphate
tripatossium orthophosphate
trisodium orthophosphate
tricalcium orthophosphate
Description: Tricalcium phosphate is a calcium salt of phosphoric acid with the chemical formula Ca3(PO4)2. It is also known as tribasic calcium phosphate and bone phosphate of lime, BPL.
sodium dihydrogen phosphate
Description: Monosodium phosphate (NaH2PO4), also known as anhydrous monobasic sodium phosphate and sodium dihydrogen phosphate, is a chemical compound of sodium with a phosphate counterion. It is used as a laxative and, in combination with other sodium phosphates, as a pH buffer.
diammonium hydrogen phosphate
potassium dihydrogen phosphate
sodium dihydrogen phosphate
potassium dihydrogen phosphate
calcium dihydrogen phosphate
tetrasodium pyrophosphate
disodium dihydrogen pyrophosphate
Description: Disodium pyrophosphate or sodium acid pyrophosphate is a buffering and chelating agent, with many food and industrial uses. It is polyvalent, and acts as a Lewis base, so is effective at binding polyvalent cations.
