Abstract

The invention belongs to the field of natural product extraction, and particularly relates to application of an organic solvent-resistant nanofiltration membrane in capsorubin pungency removal. The application comprises the following steps: dissolving capsorubin to be treated in an organic solvent, and allowing a formed solution to pass through an organic solvent-resistant nanofiltration membrane. The method disclosed by the invention is simple in pungency removal process, and the separation of the capsanthin and the capsicum oleoresin can be realized only through the organic nanofiltration membrane in one step. The process is simple, low in treatment temperature and less in color value loss.

Description

technical field [0001] The invention belongs to the field of natural product extraction, in particular to the application of an organic solvent-resistant nanofiltration membrane in capsanthin depigmentation. Background technique [0002] Capsanthin is a natural pigment that is extracted, separated and refined using scientific methods using capsicum as raw material. The main components of capsanthin are capsanthin and capsanthin. It is a deep red oil-soluble liquid with bright color and strong tinting power. It is resistant to light, heat, acid and alkali; into water-soluble or water-dispersible pigments. Capsanthin is rich in β-carotene and vitamin C, which has health care functions. Capsanthin is widely used in the coloring of various foods and medicines such as aquatic products, meat, cakes, salads, canned food, beverages, etc., and can also be used in the production of cosmetics. [0003] There are many extraction methods of capsanthin, which can be divided into two ca...
