Abstract:

Carrot fiber (CF) made from carrot pomace was modified by cellulose and then used to investigate the effect of cellulose content and reaction time on average length, average width, L/W, sugar content and accessibility of CF. The composite action of cellulase modified CF was also analyzed. The result showed that with the increasing of cellulase concentration and reaction time, the average length, average width, L/W decreased, while the sugar content and accessibility increased. Considering quantum conservation and reaction time of cellulose used, 0.4 mg/mL and 2 h were optimal for the average length, average width, L/W, sugar content and accessibility of CF.

Key words: carrot fiber, cellulase, modification, reaction condition
