Embodiment 1

[0053] A supercritical CO 2 The method for fluid extracting capsaicin from yellow cherry peppers comprises the following technical steps:

[0054] 1. Selection of peppers;

[0055] 2. Cleaning;

[0056] 3. Drying;

[0057] 4. Crushing;

[0058] 5. Supercritical CO 2 Fluid extraction of capsaicin;

[0059] 6. Post-processing;

[0060] 7. Finished product.

[0061] The raw material of this example, yellow cherry pepper, is taken from the self-built base of Zhejiang Zhongwei Brewing Co., Ltd. Yellow cherry pepper is the result of the company's "breeding and development of processed high-spicy pepper varieties" project. Yellow cherry pepper has the advantages of high spiciness and large output, which is very suitable for industrial processing and production. After the implementation of the project, the company's annual output of yellow cherry peppers can reach more than 30,000 tons, ensuring the stability of raw material supply and product quality in the production process...

Abstract

The invention discloses a method for extracting capsaicine from yellow capsicum by using supercritical CO2 fluid. The method comprises the following steps: (1) selecting yellow capsicum; (2) washing; (3) drying; (4) smashing; (5) extracting by using supercritical CO2 fluid; (6) post treating; and (7) finishing. For the method, capsaicine is extracted by using supercritical CO2 fluid extraction device, the obtained product has extremely high purity, the residual solvent accords with the national standard requirement, and the bioactivity of the extractive can be maintained to the largest extent, and the market competitiveness is promising.

Description

technical field [0001] The invention relates to a method utilizing supercritical CO 2 Fluid method for extracting capsaicin from yellow cherry pepper. Background technique [0002] Capsaicin (Capsaicin) is a component that causes pungentness in peppers, and the content in peppers is 0.1%-1%. The content of capsaicin varies with varieties, climatic conditions, ripeness of pepper fruit, soil properties, etc., and generally accumulates with the increase of ripeness of pepper fruit. Natural capsaicin is an alkaloid containing phenolic hydroxyl groups, mainly composed of five vanilla orchid substances, of which capsaicin (C 18 h 27 NO 3 ) about 69%, dioxycapsaicin (C 18 h 29 NO 3 ) about 22%, norcapsaicin (C 17 h 27 NO 3 ) about 7%, homodihydrocapsaicin and homocapsaicin were about 1%. The capsaicin crystal product is a white (or light yellow, reddish) needle-like microcrystal with a melting point range of 57-66°C and a boiling point range of 210-220°C. Soluble in met...
