Problems solved by technology

Purple corncobs are also rich in proanthocyanidins, but since corncobs cannot be eaten directly and proanthocyanidins in corncobs are difficult to extract, they are usually discarded during the processing of purple corn, resulting in a waste of proanthocyanidins resources

Abstract

The invention relates to a purple corn procyanidin extracting process, which comprises: S1, drying purple corn cob to achieve a constant weight, and breaking the dried purple corn cob to obtain purplecorn cob powder; S2, pre-treating the prepared purple corn cob powder to obtain a procyanidin-containing raw material solution; S3, extracting the active component of the raw material solution with two aqueous phases, and carrying out microwave-assisted extraction to obtain a procyanidin crude extraction solution; S4, carrying out rotary evaporation and alcohol removal on the procyanidin crude extraction solution to prepare a mixture A; and S5, adding a stabilizer to the mixture A, homogenizing, and carrying out spray drying to obtain the procyanidin extract. According to the present invention, the purple corn cob selected as the raw material is pre-treated so as to conveniently extract the active substance at the late stage, such that the purpose of the extraction of procyanidin from purple corn cob can be achieved, the waste of resources can be reduced, and the resource utilization can be increased.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a process for extracting proanthocyanidins from purple corn. Background technique [0002] Purple corn is rich in proanthocyanidins. Studies have shown that proanthocyanidins have strong antioxidant and free radical elimination effects, can effectively eliminate superoxide anion free radicals and hydroxyl free radicals, and are also involved in the metabolism of phosphoric acid and arachidonic acid and protein phosphorylation , to protect lipids from peroxidative damage. Purple corncobs are also rich in proanthocyanidins, but since corncobs cannot be eaten directly and proanthocyanidins in corncobs are difficult to extract, they are usually discarded during the processing of purple corn, resulting in a waste of proanthocyanidins resources. Contents of the invention [0003] The purpose of the present invention is to provide a process for extracting proanthocyanidins f...
