Abstract
The sugar content of citrus press liquor is enhanced by separating citrus solids, extracting fructose, glucose, and sucrose from the solids, and recombining the aqueous extract to increase the sugar content thereof. By inversion of the sucrose present in the sugar-enhanced press liquor, a high fructose syrup can be readily obtained which appears indistinguishable from high fructose corn syrup. When separation is effected by centrifugation, a colloidal phase is formed from which limonene and biocidal flavanoids can be extracted, resulting in a press liquor suitable for fermentation to alcohol. The solid residue remaining after extraction can also be recycled with the remaining press cake.
