Problems solved by technology

Traditional solvent extraction methods mostly use hot solvents (40-70°C), add solvent in a large ratio of 1:10-30 times, and extract by leaching for 1-3 hours. This kind of process has low extraction efficiency, large concentration volume, and energy consumption. High, and hot solvents are likely to cause anthocyanin degradation and decrease in physiological activity

Abstract

The invention provides a method for extracting anthocyanin from aronia melanocarpa. The method comprises the following steps: 1) selecting fruits, 2) carrying out degreasing treatment, 3) carrying outpulping and separating, 4) carrying out extraction by a mixed acid, 5) carrying out enzymolysis, 6) carrying out ultrasonic re-extraction, 7) carrying out distilling, 8) carrying out eluting, and 9)carrying out concentrating and drying. According to the method, through the steps of selecting fruits, carrying out degreasing treatment, carrying out pulping and separating, carrying out extraction by a mixed solution, carrying out enzymolysis, carrying out ultrasonic re-extraction and the like, anthocyanin contained in the aronia melanocarpa can be effectively released; through combination of the two steps of carrying out extraction by the mixed solution and carrying out ultrasonic re-extraction, the extraction is more thorough; through combination of combining degreasing, distilling and eluting steps, extraction purity is high, anthocyanin resources in the aronia melanocarpa are effectively utilized, and the added value of the aronia melanocarpa is increased. The raw material is low incost and is easy to obtain, and large-scale production is easy to realize.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a method for extracting anthocyanins from Aronia nigra. Background technique [0002] Aronia nigra is a shrub belonging to Rosaceae, which can reach a height of 3m. The root is brownish yellow, with a potential root system, and the root does not have the ability to branch. Young branches glabrous. Bark reddish brown or taupe, with obvious round lenticels, dark green leaves, single leaves, alternate; reticulated veins, leaves oval or elliptical to elliptical-oblanceolate, sharp or blunt; Pear fruit, purple-black peel, dark red flesh, kidney-shaped seeds, brown, compound corymbs, fluffy on inflorescence stalk, small flowers, anthers are drug-backed, pink; petals are white, sepals, detached calyx, green Cup-shaped; pistil ovary superior, woolly, flowering in May, fruiting in June-July.
