Problems solved by technology

Therefore, the current industrial production is still the solvent extraction method. The solvent extraction method has a large extraction capacity, but the extracted capsicum extract (low concentration capsaicin) has high impurity content and is difficult to refine.

Embodiment 1

[0032] Embodiment 1: the preparation of extractant modified ethanol solution

[0033] Dissolve 4kgNaCl in water and dilute to 100kg to obtain 4% NaCl aqueous solution; weigh 5kgNaHCO 3 Dissolve in water and dilute to 100kg to get 5% NaHCO 3 Aqueous solution: Weigh 1kg NaOH, dissolve it in water and dilute to 100kg to obtain 1% NaOH aqueous solution.

[0034] Mix 100kg 4% NaCl aqueous solution, 60kg 5% NaHCO3 aqueous solution and 40kgl% NaOH aqueous solution in a dissolving tank, then gradually add 300kg 95% edible ethanol under stirring, stir and dissolve for 10min-20min, and obtain the modified extractant weak.

Embodiment 2

[0035] Embodiment 2: the preparation of preparation

[0036] Weigh sodium acetate (CH 3 COONa·3H 2 (2) 8kg is dissolved in water and diluted to 100kg to obtain 8% sodium acetate solution; NaCl 10kg is dissolved in water and diluted to 100kg to obtain 10% NaCl solution; 4.3kg of 35% concentrated hydrochloric acid is diluted to 100kg with water 100kg to obtain 1.5% hydrochloric acid aqueous solution.

[0037] In the dissolving tank, under stirring, add 100kg of 8% sodium acetate solution, 50kg of 10% NaCl solution and 20kg of 1.5% hydrochloric acid aqueous solution, add water after mixing to dilute to 1000kg, and obtain the preparation after mixing evenly.

Embodiment 3

[0039]Add 250kg chili sticks (the chili sticks are made by crushing and granulating dried chili peppers after deseeding) to each material grain (totally 16 material grains) in the extractor, adjust the speed of the leaching outlet to 180min / r (180 minutes per revolution) ), preheat 500kg of extractant to 45°C±2°C in the preheater, then spray and leaching the chili stick layer in the feed tank, drip into the receiver through the screen at the bottom of the feed tank, and then pump it out, pass through The spray pipe sprays to the chili stick layer in the transferred material tank. According to this operation, the extractant goes through the process of "spray-drip dry-spray-drip dry", and the concentration gradually increases to form a gradient extraction, and finally obtain an appropriate concentration of leachate.

[0040] In the above leaching process, the raw materials of the new chili sticks are sprayed with a concentrated extractant, and the pepper sticks sprayed with the ...

Abstract

This invention relates to technique of extract capsicine crystal from chili. The process as follows: use NaCl, NaHCO3, NaOH water solution and ethanol to compose modified ethanol solution; spray and leach capsicum stick layer from rotary infuser, the leaching solution contraflow to leach capsicum stick layer, transit spray - drip dry - spray - drip dry continuous countercurrent leaching, gain lixivium; condense the lixivium, use mobilizing agent composed by NaCl, sodium acetate and hydrochloric acid solution to blend, then use six number solvent oil to take circumfluence extraction, obtain capsicine crystal mother liquor, then takes controlled crystallization, gain high-purity capsicine crystal.

Description

technical field [0001] The invention relates to a process for extracting capsaicin crystals from dried peppers. Background technique [0002] Natural capsaicin has unique physiological effects, and the technology of extracting capsaicin from dried peppers has been reported in many literatures. These processes mainly include solvent extraction, microwave enhanced extraction, ultrasonic enhanced extraction, supercritical CO 2 Extraction method, column chromatography and ion exchange purification method, etc. [0003] Facts have proved that there are still many difficulties in the large-scale production of microwave-enhanced extraction. Although ultrasonic enhanced extraction can realize small-scale industrial production, there are still many problems in large-scale industrialization. Supercritical CO 2 The extraction method requires a large investment in equipment. Column chromatography and ion exchange purification have a long process, many auxiliary equipment, and many t...
