Abstract
Processes for converting by-products of citrus, such as peels and juice from juice sacs attached to the peel after hand or mechanical peeling into high quality dietary fiber, naringin, juice, and oil. The processes involve pressing peels to release juice from vesicles and then grinding peels in water to create a slurry. Peel color and oil is removed by a flotation technique. Decolorized citrus peel particles—or pulp—are debittered with water in steps of boiling and washing. Dietary fiber obtained after debittering is dried and packaged for commercial use. The process promotes environmental responsibility by reducing standard citrus waste—a high BOD waste product, by overcoming discharging problems with industrial waste, by converting an environmentally undesirable product—peels, juice, and oils—into a value-added ingredient, by drastically reducing discharge and penalty cost of waste, and by eliminating the use of solvents that generate pollution.
