  2. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    The neutral value of the pH depends on the temperature and is lower than 7 if the temperature increases above 25 °C. The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2]

    A FOOD in an unopened HERMETICALLY SEALED CONTAINER that is commercially processed to achieve and maintain commercial sterility under conditions of non-refrigerated storage and distribution; A FOOD that because of its pH or A W value, or interaction of A W and pH values, is designated as a non-TCS FOOD in Table A or B of this definition;

  4. Acidity regulator - Wikipedia

    en.wikipedia.org/wiki/Acidity_regulator

    Acidity regulators, or pH control agents, are food additives used to change or maintain pH (acidity or basicity). [1] They can be organic or mineral acids, bases, neutralizing agents, or buffering agents. Typical agents include the following acids and their sodium salts: sorbic acid, acetic acid, benzoic acid, and propionic acid. [2]

  5. Gastric acid - Wikipedia

    en.wikipedia.org/wiki/Gastric_acid

    The lowest pH of the secreted acid is 0.8, [5] but the acid is diluted in the stomach lumen to a pH of between 1 and 3. There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour. [6] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...

  6. Fumaric acid - Wikipedia

    en.wikipedia.org/wiki/Fumaric_acid

    A white solid, fumaric acid occurs widely in nature. It has a fruit-like taste and has been used as a food additive. Its E number is E297. [3] The salts and esters are known as fumarates. Fumarate can also refer to the C 4 H 2 O 2− 4 ion (in solution). Fumaric acid is the trans isomer of butenedioic acid, while maleic acid is the cis isomer.

  9. Acidity function - Wikipedia

    en.wikipedia.org/wiki/Acidity_function

    In this case H 0 and H − are equivalent to pH values determined by the buffer equation or Henderson-Hasselbalch equation. However, an H 0 value of −21 (a 25% solution of SbF 5 in HSO 3 F) [5] does not imply a hydrogen ion concentration of 10 21 mol/dm 3: such a "solution" would have a density more than a hundred times greater than a neutron ...
