摘  要:
In this paper, the technical process of natural red coloring matter extracted in admired flower through many experiments was proposed. Various factors of affecting yield of the coloring matter were studied and optimal technological conditions of the extraction were determined. The results indicated that optimal conditions were 2 times extraction, 1.0h every time, 2.5% of mass fraction for chlorhydric acid and 30% volume fraction for alcohol in extraction agent. The volume ratio of raw material and extraction liquid was 1:5.5.
