Dietary fibers from citrus wastes

Dietary Fiber from Citrus Wastes Characterization... 

Nearly 5 million metric tons of citrus peel and pulp waste materials are produced annually In the manufacturing of concentrated citrus juices In Florida. Although these materials are currently processed Into cattle feed, they are rich In polysaccharides and can be considered as a source of dietary fiber. Alcohol-Insoluble solids (AIS) of 3 different fractions of the processing residues discharged from commercial juice manufacturing equipment were analyzed for pectin, easily hydrolyzable polysaccharides, and cellulose. Two varieties of orange and one of grapefruit that are the predominant citrus fruit used in Juice production were included In this study.
