Carmine

Химические свойства

Carmine is the aluminum or calcium-aluminum lake, on an aluminum hydroxide substrate, obtained by an aqueous extraction of the dried female insects of Dactylopius coccus Costa, enclosing young larvae. The primary source of the raw material is from the Canary Islands and parts of South America. The coloring principle derived from carmine chiefly consists of carminic acid (C22H20O13).

Физические свойства

Carmine occurs as bright red, friable pieces or as a dark red powder. It is soluble in alkali solutions, slightly soluble in hot water and practically insoluble in cold water and in dilute acids. CARMINE

Использование

carmine is a crimson pigment. This is the aluminum lake of the coloring agent cochineal, a natural pigment derived from the dried female insect Coccus cacti. Carmine may cause allergic reactions.

Cостав эфирных масел

The kibble consists of high concentrations of fermentable sugars (glucose, fructose, sucrose and maltose), as well as protein, pectin, cellulose, hemicellulose and polyphenols. The technical value within the seed endosperm is chemically defined as a neutral galactomannan, a high molecular weight hydrocolloid polysaccharide (polymer). The galactomannan polymer is composed of a 1,4-linked β-D-mannopyranosyl (mannose, 73 to 86% of molecule) units with single-side chains of α-Dgalactopyranosyl (galactose, 14 to 27% of molecule) units irregularly attached to every fourth or fifth mannopyranosyl unit by 1,6-glycosidic linkages to the polymer.

Общее описание

Carmine (C.I. 75470) (calcium-aluminium lacquer of carminic acid) for microscopy Certistain^?, is a dry dye that is used for the preparation of a staining solution for staining nuclei and for demonstration of glycogen in histological sections of human origin. As a Certistain^? dye it is chemically quality-certified according to highest standards and strict specifications. As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations. For more details, please see instructions for use (IFU).
