Potassium ascorbate is a compound with formula KC 6 H 7 O 6. It is the potassium salt of ascorbic acid and a mineral ascorbate. As a food additive, it has E number E303, INS number 303. Although it is not a permitted food additive in the UK, USA and the EU, [2] [3] it is approved for use in Australia and New Zealand. [4]
Ascorbic acid is an organic compound with formula C 6 H 8 O 6, originally called hexuronic acid.It is a white solid, but impure samples can appear yellowish. It dissolves freely in water to give mildly acidic solutions.
Pasteurized milk in Japan A 1912 Chicago Department of Health poster explains household pasteurization to mothers.. In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
Ascorbic acid is a weak sugar acid structurally related to glucose. In biological systems, ascorbic acid can be found only at low pH, but in solutions above pH 5 is predominantly found in the ionized form, ascorbate. [8] Many analytical methods have been developed for ascorbic acid detection.
Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.

Different food preservation methods have different impacts on the quality of the food and food systems. Some traditional methods of preserving food have been shown to have a lower energy input and carbon footprint compared to modern methods. [3] [2] Some methods of food preservation are also known to create carcinogens.
