Problems solved by technology

Using a single solvent to extract capsanthin or capsaicin cannot achieve the ideal extraction effect; moreover, in the traditional single-solvent extraction process, the ordinary large horizontal rotary extractor has problems of poor extraction effect and solvent clogging; Solvent evaporation and dehydration adopts horizontal dryer or ordinary vertical evaporator, which has the problem of incomplete desolventization and agglomeration. loss

Embodiment Construction

[0015] Utilize n-hexane and acetone mixed double solvent one-step method to extract capsanthin and the specific steps of capsaicin as follows:

[0016] a. The chili powder is granulated to form chili granules. After the chili granules are dried, the moisture content is 8-12%, and then the chili granules are quantitatively fed into the box chain extractor;

[0017] b. The n-hexane and acetone are mixed in the solvent mixing tank according to the mass ratio of 9-6:1. After mixing, sedimentation and dehydration are carried out, and the mixed solvent is poured into the extractor according to the ratio of the material-to-solvent ratio of 1:2.5-4. , the temperature of the mixed solvent is 40-50℃;

[0018] c. The pepper particles are kept in a material layer of 500-700 mm in the box-chain extractor for 1-3 hours; and the sieve plate is backwashed according to the infiltration;

[0019] d. The extracted residue enters the vertical face plate steaming machine. First, the residue is de...

Abstract

The invention discloses a method for extracting capsicum red pigment and capsaicin, comprising the following steps of: extracting capsicum particles in a case chain type extractor by the use of a mixed solvent of hexane and acetone; allowing the extracted capsicum residue to enter into a vertical faceplate evapo-separated machine for desolvation; allowing the extracted mixed solvent containing capsicum red pigment and capsaicin to enter into a filtration and evaporation system to obtain a mixture of capsicum red pigment and capsaicin; and allowing the mixed solvent which has undergone condensation recovery to enter into a separator for separation. By the adoption of the method, the yield of capsicum red pigment is raised, capsaicin is fully extracted and the extraction effect is good; desolvation is thorough and there is no agglomeration and obstruction phenomenon; a negative pressure technology is adopted to reduce steam consumption, the yield of capsicum red pigment and capsaicin is increased, and the process operation is stable.

Description

technical field [0001] The invention relates to the field of solvent extraction of capsanthin and capsaicin, in particular to a method for extracting capsanthin and capsaicin by one-step method using n-hexane and acetone mixed with two solvents. Background technique [0002] The natural product extraction, processing and application industry with capsaicin and capsaicin as the mainstream has gone through a history of more than ten years, and has also ushered in a new period of development and competition opportunities. In recent years, with the restricted use of artificial pigments in many fields, the number of synthetic pigments legally used in various countries has been continuously reduced. In addition, the research and development costs of artificial synthetic pigments are high and production restrictions are large. The application of capsicum oleoresin continues to expand, and the demand is year by year. rise. Capsicum oleoresin is a mixture of capsanthin and capsaicin...
