Abstract

The invention discloses a method for extracting anthocyanin from fructus aroniamelanocarpae pomace, which includes the following steps: (1) fructus aroniamelanocarpae pomace and first extract are stirred and extracted under 4 DEG C to 10 DEG C and pH is equal to 3 to 4; and by filtration, first filtrate and first filter residue are obtained; (2) the first filter residue is added with second extract, and is stirred and extracted under 4 DEG C to 10 DEG C and pH is equal to 3 to 4; and by filtration, second filtrate and second filter residue are obtained; (3) by using aqueous ethanol solution, the second filter residue is stirred and extracted under 4 DEG C to 10 DEG C and pH is equal to 3 to 4; (4) the first filtrate is concentrated by reducing pressure; and filtration is carried out; (5) the filtrate is loaded onto macroporous resin, aqueous ethanol solution is used for resolution, resolved solution is collected, and after concentration and drying, an anthocyanin extract is obtained. The method is carried out under low temperature, and the degradation and physiological activity decrease of anthocyanin are prevented. Weak acid prevents the partial and complete hydrolysis of acylated anthocyanin as the result of subsequent evaporation and concentration. The use of the filtrates shortens the time of concentration, reduces energy consumption, and saves new solvent, and the yield of anthocyanin is high.

Description

technical field [0001] The invention relates to a method for extracting anthocyanins from Aronia adenocarpus pomace, belonging to the technical field of plant extraction. Background technique [0002] Aroniamelanocarpa is a species of Rosaceae Aronia genus, a deciduous shrub berry. Native to northeastern North America, it is distributed from the Baltic Sea coast to the Pacific coast. Since the introduction of the species in my country, studies on reproduction, cultivation, and regional tests have been completed successively. This tree species is a precious tree species with edible, medicinal, garden and ecological values. The fruit of Aronia nigra has extraordinary health effects. The fruit and its extracts have special curative effects on cardiovascular and cerebrovascular diseases such as heart disease and hypertension, and are widely used in medicine and functional food industries in Europe and America. Anthocyanins, flavonoids (fresh fruit content as high as 0.25%-0.3...
