ABSTRACT:
An improved process is provided for the recovery of useful products from orange peels derived from the processing of oranges. The peel is contacted with a solution comprising a non-aqueous water-miscible solvent to extract the sugars, essential oils, and bioflavanoids contained therein. The solvent-extracted peel is dried to produce a product high in cellulose and pectin. The extract is diluted with an aqueous solution to render the essential oils insoluble, with the essential oils being recovered from the extract, causing the bioflavanoids to precipitate and permit their recovery by filtration. The remaining portion of the extract may be recovered and purified to provide a sugar syrup.
