How to make Pure Capsaicin Crystals
How to make Pure Capsaicin Crystals Option 1: In a single-stage continuous countercurrent ultrasonic extractor, combine 1 kg of crude chili extract with 8 kg of beta-cyclodextrin alkaline solution. Set the extractor to operate at 80 kHz frequency, 300 W power, and maintain a temperature of 10°C. Perform countercurrent extraction for 45 minutes to obtain the extracting solution. Filter the extracting solution to separate the filtrate from the residue. Repeat the ultrasonic extraction on the residue twice, filtering after each extraction, and combine all filtrates. Concentrate the combined filtrate to reduce its volume to 1/20 of the original. Mix 2 L of the concentrated solution with 20 L of 55% ethanol. Allow the mixture to stand for 30 minutes, then perform suction filtration at 40°C. Separate the filtrate from the residue. Repeat the suction filtration on the residue two additional times, merging all the filtrates. Evaporate the filtrate under reduced pressure at 40°C and 0.1 mP...
