Abstract: A microchannel device, including a homogenization chamber, a deceleration-cooling channel, an acidity regulation channel, a microchannel reaction chamber, and an ultrafiltration desalination chamber. A method for preparing high-oil-load microcapsules using the aforementioned microchannel device, including: preparing an aqueous phase and an oil phase; feeding the aqueous phase and the oil phase to the homogenization chamber to form a first emulsion; cooling the first emulsion; adjusting pH of the first emulsion with dilute hydrochloric acid; feeding the first emulsion to the microchannel reaction chamber to form a second emulsion with a core-shell structure; removing Na+ and Cl− from the second emulsion; and subjecting the second emulsion to spray drying to obtain the high-oil-load microcapsule powder.
