A New Method of Juice Concentration using a Hydrogen Bubbles Photoelectroflotation Process Powered by Solar
Abstract: Currently, juice concentrates are produced by extracting water from freshly squeezed juice. To extract water from freshly squeezed juice, one of the following methods is used: evaporation, freezing of water, or the use of diaphragms. When evaporating, freshly squeezed juice is heated in a vacuum in special trays, but not to the boiling point, since boiling the juice will destroy all its useful substances. The mass, obtained after evaporation is …
