Method for extracting capsanthin from chilies

Abstract

The invention discloses a method for extracting capsanthin from chilies. The method comprises the following steps: 1, preparing chilli powder, an adhesive and dry ice, pulverizing the dry ice at -90 to -80 DEG C to obtain powder, and uniformly stirring and mixing the dry ice powder, the chilli powder and the adhesive; 2, granulating the mixed powder by adopting a granulator at a temperature of -90DEG C to -80 DEG C, and spreading the granules in a room-temperature environment for 30-40 minutes; 3, mixing the spread particles with 80-90 wt% of ethanol, stirring for 50-60 min at a speed of 40-50 r / min, and filtering to obtain filtrate; and 4, centrifuging the filtrate obtained in the step 3, collecting the supernatant, and freeze-drying into powder to obtain the capsanthin. According to themethod, chilli particles are put into 80-90 wt% ethanol, and due to the arrangement of holes in the chilli particles, the contact area between the chilli particles and the ethanol is greatly increased, so that the dissolution speed and the dissolution amount of capsanthin can be increased so as to improve the extraction efficiency and the yield of capsanthin.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, in particular to a method for extracting capsanthin from capsicum. Background technique [0002] Red pepper is a common agricultural product, which contains capsaicin (spicy flavor), natural red pigment and so on. Low-level capsicum is used as a condiment, and high-level capsicum has analgesic, anti-inflammatory, and bactericidal effects; capsanthin is a natural red pigment that can be used in medicine or advanced cosmetics without any toxic and side effects. [0003] The traditional production of capsicum red and capsicum essence all use paprika powder as raw material for extraction, the equipment capacity is not fully utilized, the filtration speed is slow, there are many residual solvents in the material, and the pigment extraction rate is low. [0004] In order to solve the above problems, in the existing technology, the capsicum powder is granulated and then extracted. As...

Problems solved by technology

[0006] In the above patent document, the chili powder is granulated and then extracted. Although the extraction speed is increased, the extraction efficiency is improved, and the extracted red pigment is of high purity, due to the structure of the chili powder into granules, the capsanthin inside the granules is not easy to be extracted. Extraction solvent fusion extraction, because the amount of capsanthin extracted is less
