Technique for extracting edible natural red color element from psammophyte of nitraria

Abstract

The present invention relates to an extraction process for extracting edible natural red coloring matter from psammophyte nitraria sibiria. Said invention uses the fruit of wild nitraria sibiria as raw material and adopts the processes of ethyl alcohol extraction, removing impurities, concentrating and drying so as to obtain the invented product which has high color fastness for protein, starch and sugar, etc. and can be used for coloring beverage, sweets, liquor and other foods.

Description

technical field

[0001] The invention belongs to the field of food chemistry, and relates to a method for preparing edible natural pigments, in particular to a process for extracting edible natural red pigments from psammophyte Nitraria japonica. Background technique

[0002] With the continuous deepening of research on the hazards of artificially synthesized food coloring to human health, its use is increasingly restricted. At the same time, with the enhancement of people's psychological needs of advocating nature, returning to nature, and safety first, natural pigments have been valued and developed rapidly. Although natural pigments are more expensive and are often limited by processing conditions, because they come from nature, they often have certain nutritional and health value, and even medicinal value.
