specific Embodiment approach

[0007] The technical measure that the present invention takes and specific implementation are as follows:

[0008] The three-stage extraction method of the present invention prepares capsaicin, capsicum essence and capsicum red three kinds of extracting solutions as follows: its first section is to put a certain amount of red pepper raw material in the extraction container, press 1: 8~12 Adding concentration is 50%~80% ethanol solution, leaching at the temperature of 30 ℃~60 ℃ for 4~6 hours, obtain capsaicin extract after filtering; Its second section is by the weight of 1:6~10 Compared to adding the ethanol solution with a concentration of 80% to 95% in the extraction container, heat reflux extraction at a temperature of 70°C to 90°C for 1 to 3 hours, and filter to obtain the capsicum extract; the third section is according to 1: Adding ethanol solution with a concentration of 85% to 95% into the extraction container at a weight ratio of 4 to 8, heat reflux extraction at a te...

Embodiment 1

[0011] Put a certain amount of red capsicum raw material in the extraction container, add the ethanol solution that concentration is 50% by the weight ratio of 1: 12, leaching 4 hours at the temperature of 60 ℃, obtain capsaicin extract through filtering; Adding concentration is 95% ethanol solution in extracting container in the weight ratio of: 6, heat reflux extraction 1 hour at 90 ℃ of temperature, get capsicum essence extract through filtering; Finally by the weight ratio of 1: 8 in the extracting container Add an ethanol solution with a concentration of 85%, extract under reflux at a temperature of 65° C. for 2.5 hours, and filter to obtain a capsanthin extract.

[0012] Carry out decompression concentration and distillation respectively to three kinds of extraction solutions again, be about to place three kinds of extraction solutions respectively in decompression concentration tank and film evaporator and carry out concentration and distillation removal, reclaim ethanol...

Embodiment 2

[0014] Put a certain amount of red capsicum raw material in the extraction container, add the ethanol solution that concentration is 80% by the weight ratio of 1: 8, leaching 6 hours at the temperature of 30 ℃, obtain capsaicin extract through filtering; Adding the ethanol solution that the concentration is 80% in the extraction vessel at a weight ratio of : 10, extracting under reflux at a temperature of 70° C. for 3 hours, and obtaining capsicum essence extract through filtration; finally going to the extraction vessel at a weight ratio of 1: 4 Add a 95% ethanol solution, extract under reflux for 0.5 hour at a temperature of 85° C., and filter to obtain a capsanthin extract.

[0015] Carry out decompression concentration and distillation respectively to three kinds of extraction solutions again, be about to place three kinds of extraction solutions respectively in decompression concentration tank and film evaporator and carry out concentration and distillation removal, reclai...

Abstract

The invention provides a technological method of extracting and separating capsaicin, capsicum red pigment and capsicum oleoresin crude products from red pepper, which adopts the red pepper pulverized with a certain particle size as material and hydrous ethanol as extraction solvent, and three-stage extraction method for the preparation of the three extracts of capsaicin, capsicum oleoresin and capsicum red pigment separated in the extraction phase. The three extracts are respectively vacuum concentrated and distilled, and the crude products of capsaicin, capsicum red pigment and capsicum oleoresin can be gotten after the solvent recovery and solvent residue removal. The extracting and separating method separates the capsaicin, capsicum oleoresin and capsicum red pigment in the extraction phase by using the same extraction tank and solvent, avoids the trouble of separating the capsaicin and capsicum red pigment in the late workshop section, eliminates the alkali and acidification treatments or the separation craft of column chromatography, facilitates the improvement of the output ratio of capsicum red pigment and capsaicin. The technological method of extracting and separating capsaicin, capsicum red pigment and capsicum oleoresin crude products from red pepper has the advantages of simple technique, easy operation and control, less equipment investment, easy solvent recovery and reuse, low cost, short cycle, high yield of active ingredient, and better suitability for commercial and mass production.

Description

technical field [0001] The invention belongs to the field of fine chemical production industry, and proposes a process method for extracting and separating capsaicin, capsanthin and capsicum concentrate and coarse products from red peppers. Background technique [0002] Capsaicin, capsaicin and capsanthin all have extensive and important uses. Capsaicin is mainly used in four aspects: medicine, biochemical pesticide, functional coating and defense weapon. Capsanthin is mainly used as a food additive, which can color a variety of foods in a variety of shades; it is widely used in the production of high-grade poultry feed such as medicine, cosmetics, and chickens and ducks; it has been widely used in textile dyeing, paint, and plastic coloring abroad . Chili extract is mainly used as raw material in the food industry. It can be used as seasoning in restaurants, canteens, and households, or directly used for cooking, seasoning and coloring. The most important use is as a chil...
