[0018] Example 1
[0019] Process flow of the method for preparing water-insoluble dietary fiber from the residue of Gracilaria agar processing
[0020] Add 30 times of water to the dry weight of the red algae plant Gracilaria agar residue, stir and let it stand, then collect the Gracilaria agar residue, dry it for later use; add 0.01 mol / L hydrochloric acid solution to the obtained dried Gracilaria agar residue, add The ratio is that the weight (g) of the dry Grapefruit agar residue and the volume (ml) of the acid solution are 1:20. The obtained liquid is refluxed and stirred at 55 ° C for 2 hours, cooled to room temperature naturally, and filtered by a centrifuge to remove the water-soluble dietary fiber. The gracilis agar residue is for subsequent use; adding a concentration of 5% H in the obtained gracilis agar residue 2 O 2 solution, the added ratio is the weight of Gracilaria agar residue (g) and H 2 O 2 The volume (ml) ratio of the solution is 1:15. Stir and ble...
