ABSTRACT

Cellulose was isolated from apple press-cake in the form of a hydrogel, using dilute sodium hydroxide and hydrogen peroxide. The gel was characterized as a pseudo-plastic fluid. Its flow properties were similar to those of furcellaran, guar and xanthan gums. Freeze drying and milling apple cellulose gel impaired its hydrophilic character, but the particles nevertheless showed a tendency to wet and redisperse easily.
