Calcium hydroxide has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide.
Nixtamalization ( / ˌnɪkstəməlɪˈzeɪʃən /) is a process for the preparation of maize, or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates ), [ 1] washed, and then hulled. The term can also refer to the removal via an alkali process of the ...
Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...
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. It has many uses in industry.
Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 42– anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
Commercial heat sources for self-heating food packaging use an exothermic (heat releasing) reaction, for which there are several common formulations. These include: Quicklime aka calcium oxide, and water. Quicklime, inexpensive and readily available, is generally recognized by the FDA as safe. [2] The product of the reaction is calcium hydroxide.
Calcium lactate is a white crystalline salt with formula C 6 H 10 CaO 6, consisting of two lactate anions H 3 C (CHOH) CO − 2 for each calcium cation Ca 2+. It forms several hydrates, the most common being the pentahydrate C 6 H 10 CaO 6 ·5 H 2 O. Calcium lactate is used in medicine, mainly to treat calcium deficiencies; and as a food ...
The term calcium phosphate refers to a family of materials and minerals containing calcium ions (Ca 2+) together with inorganic phosphate anions. Some so-called calcium phosphates contain oxide and hydroxide as well. Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth ...
