Embodiment Construction

[0021] 1. Using supercritical CO 2 Extraction and separation of capsicum oleoresin:

[0022] (1) Pulverize and dry the chili powder into chili powder; (2) put the chili powder into supercritical CO 2 In the extraction kettle 5, heat the preheater 3 with circulating hot water, and adjust the temperature of the extraction kettle and the separators 6 and 7 connected thereto to 40-60°C; (3) the CO 2 CO in tank 1 2 The supercritical gas is generated after being injected into the preheater by the metering pump 2, and then enters the CO after being metered by the meter 4. 2 Extraction kettle 5; (4) when CO 2 When passing through the material layer, the capsicum oleoresin contained in the paprika is dissolved in supercritical CO 2 In the gas, when the extraction pressure is reached, slowly open the outlet valve of the extractor to keep the extraction pressure stable at 26-28Mpa; (5) supercritical CO 2 Together with its dissolved substances, it is separated by separators 6 and 7, ...

Abstract

The invention relates to a method for extracting chilli oil resin from chilli. The method comprises the following steps: 1, extracting and separating the chilli oil resin by utilizing supercritical CO2; 2, purifying the extracted chilli oil resin by means of short-path molecular distillation; and 3, increasing the water solubility of the purified chilli oil resin by utilizing an emulsification solubilizing technology, and finally wrapping the chilli oil resin by utilizing a microcapsule technology to obtain an antiseptic seasoning. The method provided by the invention has the advantages that 1, the extraction efficiency of the chilli oil resin is improved by adopting the CO2 supercritical extraction technology; 2, the purity of the chilli oil resin reaches over 95% by using the short-path molecular distillation technology; 3, the water dispersion of the chilli oil resin is improved by adopting the emulsification solubilizing technology; 4, the chilli oil resin is powdered by utilizing the microcapsule technology, so that the product performance is more stable; and 5, the extracted chilli oil resin does not contain organic solvent and heavy metal residue.

Description

Technical field: [0001] The invention relates to a method for extracting a natural antiseptic of spices, in particular to a method for extracting capsicum oleoresin from capsicum. Background technique: [0002] Capsicum oleoresin, as a colorant and flavoring agent, is widely used in various food flavoring and coloring. Its main components are capsaicin, capsanthin and carotene, and it also contains tartaric acid, malic acid and citric acid. The traditional extraction method is to use organic solvents (such as acetone, ether, ethanol, etc.) to extract and refine the dried capsicum to obtain capsicum oleoresin. Its disadvantage is that the safety of the extraction process is poor (flammable), and there are organic solvents and heavy metal residues in the extract. Invention content: [0003] The purpose of the present invention is just to overcome the deficiencies that exist in the above-mentioned prior art, and provide a kind of method extracting capsicum oleoresin from ca...
