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. Combine the two effluents, concentrate under reduced pressure at a vacuum pressure of 0.06mpa and a temperature of 55°C, recover ethanol, and 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, and the n-he...
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 essence solution to flow out of the chromatographic column at 50 ml / min, and collects the effluent. After the solution has flowed out, rinse the chromatography column with clear water, flow out the chromatography column at 80 ml / min, rinse until the effluent is nearly colorless, discard the effluent, and elute the chromatography column with 50% ethanol. And flow out the chromatographic column with 20 milliliters / minute, 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...
Embodiment 3
[0034] 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 valve of the chromatographic column to let the capsicum essence solution flow out of the chromatographic column at 40 ml / min, and collect the effluent. The liquid was nearly colorless, and 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. Use n-hexane to elute the chromatographic column until the chromatographic column flows out at 30 ml / min until the effluent is nearly colorless, collect the n-hexane eluate, concentrate under reduced pressure, reclaim the n-hexane to obtain 524....
