Problems solved by technology

However, the chromatographic column made of the above two adsorbents cannot recover the pigment, the mass transfer rate is slow, the column efficiency is poor, the recovery rate is low, and the solvent consumption is large, it is difficult to realize industrialized large-scale production, and the adsorbent cannot be recycled. polluted environment
[0003] In the method of refining capsicum pigment by using chromatographic column, Chinese patent CN1392201A uses macroporous adsorption resin to separate capsaicin, which has large solvent consumption, complicated operation and low yield, and has not been applied to the production of decolorized capsicum essence

Embodiment 1

[0025] Add 20 kg of HPD-100A macroporous molecular adsorption resin to the chromatography column, soak it with 50 L of ethanol (95%) for 2 hours, and then wash it with clean water, repeating three times. Use 20L of 70% to 90% ethanol to dissolve the crude capsicum essence, inject it into the chromatography column, absorb it at room temperature for 2 hours, put it into the solution at a certain flow rate and collect it, rinse the chromatography column with water, and discard the effluent. Then use 50% ethanol solution to elute the chromatography column until the effluent has no spicy taste. The two effluents were combined, concentrated under reduced pressure at a vacuum pressure of 0.06 MPa and a temperature of 55° C., and recovered ethanol to obtain decolorized capsicum extract. Then use n-hexane to elute the chromatography column until the effluent is nearly colorless, the vacuum pressure is 0.08MPa, the temperature is 40°C, the effluent is concentrated under reduced pressure...

Embodiment 2

[0027] Dissolve 1 kg of No. 1 capsicum essence (color value of No. 1 capsicum essence is 10; capsaicin content is 6.6%) in 40L of 90% ethanol solution, inject the capsicum essence solution into the chromatographic column, let stand for 3 hours, and open the chromatographic column The valve allows capsicum extract solution to flow out of the chromatographic column at 50 ml / min, and collects the effluent. After the solution has flowed out, wash the chromatographic column with clear water, flow out the chromatographic column at 80 ml / min, rinse until the effluent is nearly colorless, discard the effluent, elute the chromatographic column with 50% ethanol, and Flow out the chromatographic column at 20 ml / min, and elute until the effluent has no spicy taste. The eluate was collected and combined with the first ethanol collection of capsicum extract, concentrated under reduced pressure, and the ethanol was recovered to obtain 762.1 g of decolorized capsicum extract. Use n-hexane to...

Embodiment 3

[0035] No. 2 capsicum extract (color value of No. 2 capsicum extract is 15; capsaicin content is 4.2%) 2kg is dissolved in 60L of 80% ethanol solution, the capsicum extract solution is injected in the chromatographic column, and left standstill for 4 hours. Open the chromatographic column valve to allow capsicum essence solution to flow out of the chromatographic column at 40 ml / min, and collect the effluent. After being colorless, the effluent was discarded. Use 70% ethanol solution to elute the chromatographic column until the effluent has no pungent taste, collect the eluent and combine with the first capsicum extract ethanol collection, decompress and concentrate to obtain decolorized capsicum extract as 1.02kg. The chromatographic column was eluted with n-hexane until the chromatographic column flowed out at 30 ml / min until the effluent was nearly colorless, the n-hexane eluate was collected, concentrated under reduced pressure, and the n-hexane was reclaimed to obtain 52...

Abstract

The invention provides a method for separating discolored chili extract from chili pigment in crude products of chili extract, which relates to a process for separating discolored chili extract from chili pigment. The method comprises the following steps: (1) soaking macroporous molecular adsorption resin by ethanol; (2) fully dissolving the crude products of chili extract by the ethanol; (3) injecting the chili extract solution into a chromatography column in which the molecular adsorption resin is filled, and standing; (4) enabling the solution to flow out of the chromatography column; (5) leaching by clear water; (6) eluting the chromatography column by the ethanol solution; (7) mixing the eluent and the ethanol effluent liquid, and carrying out decompression concentration to obtain the discolored chili extract; (8) eluting the chromatography column by normal hexane; and (9) collecting the eluent in the step (8), and carrying out decompression concentration to obtain the chili pigment without pungency. The invention overcomes the defects in the process of producing the discolored chili extract by activated carbon and diatomite, realizes the large-scale industrialized productionof the discolored chili extract, can recycle the chili pigment to refine high-grade chili pigment, and is a cleaning project with low energy consumption and high efficiency.

Description

technical field [0001] The invention relates to a chemical process, in particular to a process for separating decolorized capsicum essence and capsicum pigment. Background technique [0002] At present, in the process of producing decolorized capsicum extract, active carbon and diatomaceous earth are mostly used as adsorbents to separate pigments. However, the chromatographic column made of the above two adsorbents cannot recover the pigment, the mass transfer rate is slow, the column efficiency is poor, the recovery rate is low, and the solvent consumption is large, it is difficult to realize industrialized large-scale production, and the adsorbent cannot be recycled. polluted environment. [0003] In the method of refining capsicum pigment by chromatographic column, Chinese patent CN1392201A utilizes macroporous adsorption resin to separate capsaicin, which has large solvent consumption, complicated operation and low yield, and has not been applied to the production of de...
