Product Name:Food Blue No. 1 Aluminum Lake
English Name:Food Blue No. 1 Aluminum Lake
CAS No.:16521-38-3
Aliases:Food Blue No. 1 Aluminum Lake, Brilliant Blue FCF Aluminum Lake, Edible Blue No. 1 Aluminum Lake
Physical Properties:This product is a violet-blue fine powder, odorless. It is almost insoluble in water and organic solvents. It has strong light resistance and heat resistance, with stability superior to indigo disulfonate. It appears deep violet-blue in dilute sulfuric acid; after heating in 10% sodium hydroxide solution, it dissolves to a yellow-brown color, and upon acidification, a violet-blue gelatinous precipitate is formed. Contains aluminum, no definite melting point, decomposes at high temperature.
Uses:Mainly used as a food colorant for coloring pastries, candies, beverages, ice cream and other foods; also used for coloring pharmaceuticals and cosmetics. Due to its insolubility in water, it is especially suitable for oily foods and applications requiring insoluble pigments.
Technical Specifications:
Appearance: violet-blue fine powder, odorless.
Solubility: almost insoluble in water and organic solvents.
Light and heat resistance: strong, superior to indigo disulfonate.
Identification reaction: deep violet-blue in dilute sulfuric acid; yellow-brown after heating in 10% sodium hydroxide solution, turning violet-blue with gelatinous precipitate upon acidification.
Aluminum salt test: positive; white gelatinous precipitate formed with ammonium chloride and ammonia test solutions, insoluble in excess ammonia test solution.
