Experimental design, materials and methods

The experiments was carried out to determine the relationship between cellulase hydrolysis, acid treatment and particle size distribution and the monosaccharide composition, X-ray diffraction, Fourier-transformed infrared and spectroscopy surface area of coconut cake dietary fiber. Firstly, defatted coconut cake dietary fiber (DCCDF) was prepared from defatted coconut cake with α-amylase, papain and glucoamylase. Then DCCDF was subjected to acidic treatment and cellulase hydrolysis respectively, and defatted coconut cake dietary fiber treated by acid (DCCDF-A) and defatted coconut cake dietary fiber treated by cellulase hydrolysis (DCCDF-C) were obtained. Secondly, the chemical composition, particle size distribution, color, surface and microstructure, X-ray diffraction and Fourier-transformed infrared spectroscopy of DCCDF, DCCDF-A, DCCDF-C were determined [2], [3], [4], [5], [6].
