Problems solved by technology

In the existing capsaicin extraction process, the solvent usually uses organic solvents such as ethanol, ethyl acetate, and n-hexane. The use of these solvents has the following defects: 1. During the production process in the workshop, it will cause different degrees of damage to the body of the operator ; Two, flammable and explosive organic solvents have great potential safety hazards; three, in the later refining process, it is necessary to heat and remove residual organic solvents, which consumes a lot of energy and increases the cost

Embodiment 1

[0025] (1) Choose the naturally grown high-spicy pepper, the mature fruit of the devil pepper (the origin is India, which has been introduced and planted in China) as raw material, and dry it naturally to make dried pepper, remove the pepper seeds from the dried devil pepper, and crush it into a particle with a diameter of < 1mm paprika;

[0026] (2) To prepare A solution, mix half of sodium carbonate and disodium hydrogen phosphate to make a 1-20% solution, that is, A solution;

[0027] (3) Put the devil's chili powder into solution A, the weight ratio of material to liquid is 1:6, stir and extract at 60°C for 3 hours, filter to separate the material and liquid; Extract 2 times for 1:4, and combine the extracted extracts extracted three times;

[0028] (4) At 50°C, filter with diatomaceous earth for 3 times, and use the filtrate for later use; because the extract contains viscous substances, diatomite-assisted filtration can effectively prevent the filter paper or filter scr...

Embodiment 2

[0032] (1 choose high-spicy dry chili, and remove the chili seeds;

[0033] (2) To prepare A solution, choose sodium bicarbonate, sodium phosphate, and ammonium chloride to mix one-third each to make a 10% solution, namely A solution;

[0034] (3) Put the devil's chili powder into solution A, the weight ratio of material to liquid is 1:3, stir and extract at 40°C for 5 hours, filter, and then use solution A with the material residue to make the weight ratio of material to liquid 1:2 in the same way. Extract 2 times and combine the extracts extracted three times;

[0035] (4) At 70°C, filter twice with diatomaceous earth, and use the filtrate for later use;

[0036] (5) Adjust the pH value of the filtrate obtained in step (4) to 8 with 5% phosphoric acid solution, let stand for 24 hours, filter, and vacuum dry to obtain capsaicin with a capsaicin content greater than 60-80%.

[0037] Finally, adjust the pH value of the waste liquid to 7 with acid and discharge it.

Abstract

The invention discloses a method for extracting natural capsaicine from chilies. According to the method, smashed chili powder is put in a 1%-20% solution A prepared by mixing carbonate and phosphate or ammonium salt, and then filtration and drying are performed to obtain the natural capsaicine. The method has the advantages that the process is simple, the extraction rate is high, and cost is low; raw materials used are safe and free of toxicity, and the extracted natural capsaicine contains few impurities and is high in quality and suitable for popularization and large-scale production.

Description

technical field [0001] The invention relates to a method for extracting natural capsaicin. Background technique [0002] Natural capsaicin, also known as capsaicin, has strong analgesic and anti-inflammatory properties and is widely used to treat conditions such as arthritis, muscle pain, back pain, sports sprains, and postherpetic neuralgia. In the existing capsaicin extraction process, the solvent usually uses organic solvents such as ethanol, ethyl acetate, and n-hexane. The use of these solvents has the following defects: 1. During the production process in the workshop, it will cause different degrees of damage to the body of the operator Two, flammable and explosive organic solvents have great potential safety hazards; three, heating to remove residual organic solvents in the later refining process requires a lot of energy consumption and increased costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome th...
