Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris , and another occurs naturally as the mineral gypsum .
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. [4] It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk.
The International Numbering System for Food Additives (INS) is an international naming system for food additives, aimed at providing a short designation of what may be a lengthy actual name. [1] It is defined by Codex Alimentarius , the international food standards organisation of the World Health Organization (WHO) and Food and Agriculture ...
The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]
For example, in the UK, food companies are required to include the "E number(s)" in the ingredients that are added as part of the manufacturing process. Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g. vitamin C ( E300 ) and lycopene ( E160d ...
Calcium lactate – food acid; Calcium lactobionate – stabilizer; Calcium malates – food acid; Calcium oxide – mineral salt; Calcium pantothenate (Vitamin B 5) – Calcium peroxide – Calcium phosphates – mineral salt, anti-caking agent, firming agent; Calcium polyphosphates – anti-caking agent; Calcium propionate – preservative ...
Firming agents are food additives added in order to precipitate residual pectin, thus strengthening the structure of the food and preventing its collapse during processing. These are salts, typically lactates or phosphates, calcium salts or aluminum sulfates. [1] They are mainly used for (fresh) fruit and vegetables.
Calcium dihydrogen phosphate is used in the food industry as a leavening agent, i.e., to cause baked goods to rise. Because it is acidic, when combined with an alkali carbonate ingredient, commonly sodium bicarbonate (baking soda) or potassium bicarbonate, it reacts to produce carbon dioxide and a salt. Outward pressure of the carbon dioxide ...
