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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
