Properties
Chlorophyll is an oil-soluble colour that can be extracted from a range of green leaves, but usually, grass, nettles or alfalfa is used. Chlorophyllin is obtained by the coppering of chlorophyll following its alkaline hydrolysis. This is a water-soluble colour and provides a green/blue to yellowish-green colour. The improved stability and brightness of copper chlorophyllin lead to its much wider use than chlorophyll as a food colour.
Applications
Typical applications for chlorophylls include confectionery, instant food, soft drinks, soups, beverages, soaps, cosmetics, ice cream, jellies, desserts, beverages, dairy products, fruit preparation, bakery products, sauces, snack food, seasonings, and convenience food.
