Death by sodium nitrite ingestion can happen at lower doses than the LD Lo. [53] [54] Sodium nitrite has been used for homicide [55] [56] and suicide. [57] [58] To prevent accidental intoxication, sodium nitrite (blended with salt) sold as a food additive in the US is dyed bright pink to avoid mistaking it for plain salt or sugar. In other ...
Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats ...
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
Nitrosation is typically performed with nitrous acid, formed from acidification of a sodium nitrite solution. Nitrous acid is unstable, and high yields require a rapid reaction rate; NO + synthon transfer is catalyzed by a strong nucleophile, such as (in increasing order of efficacy) chloride, bromide, thiocyanate, or thiourea.
Sodium erythorbate (C 6 H 7 NaO 6) is a food additive used predominantly in meats, poultry, and soft drinks.Chemically, it is the sodium salt of erythorbic acid.When used in processed meat such as hot dogs and beef sticks, it increases the rate at which nitrite reduces to nitric oxide, thus facilitating a faster cure and retaining the pink coloring.
The nitrite ion has the chemical formula NO − 2. Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.
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 ...
Curing salt. Curing salt is used in meat processing to generate a pinkish shade and to extend shelf life. [1] It is both a color agent and a means to facilitate food preservation as it prevents or slows spoilage by bacteria or fungus. Curing salts are generally a mixture of sodium chloride (table salt) and sodium nitrite, and are used for ...
