Neutral-detergent fiber value

Hamlin and Valencia washed orange pulp from several crop years were dried and analyzed. The range in values of total pectin, neutral detergent fiber and crude fiber were 26.0-45.6%, 15.8-31.0% and 9.9-20.6% respectively. In addition, detailed nutrient and dietary fiber analyses were obtained for selected samples. Functional properties such as flavor muting, chromatophore formation and oil holding properties were noted. Food processing modification yields a novel form of the hydrated pulp with extended functional properties. 

The soluble dietary fiber is not measured in the proximate analysis because crude fiber is the residue obtained after the food sample is subjected to sequential hydrolyses with acid and alkali. The crude fiber clearly underestimates values when compared with other methods of analysis such as dietary fiber and detergent fiber. The acid and neutral detergent fiber analyses were developed to estimate hemicellulose, cellulose, and lignin of forages.
