[0032] The preparation method of the sweet potato coarse dietary fiber superfine powder is as follows: adding wet sweet potato dietary fiber into a superfine pulverizer, pulverizing at room temperature for 1 minute, and passing through a 100-mesh sieve to obtain the product.
[0033] The preparation method of the modified sweet potato coarse dietary fiber powder by high static pressure synergistic enzymatic hydrolysis is as follows: add 0.05% pectinase and 0.001% cellulase by weight of crude dietary fiber to wet sweet potato crude dietary fiber, treat at 300MPa for 20min, 50 Dry at -60°C for 24 hours, pulverize with a universal grinder and pass through a 100-mesh sieve.
[0034] The preparation method of the extruded puffed sweet potato coarse dietary fiber powder is as follows: adding the wet sweet potato dietary fiber into an extruder, extruding at 100°C, screw rotating speed at 800rpm, pulverizing with a universal grinder, and passing through a 100-mesh sieve to obtain the p...
Embodiment 1
[0035] Embodiment 1 is used to make each raw material ratio of the bread that is rich in sweet potato dietary fiber
[0036] In this embodiment, the raw materials used to make bread rich in sweet potato dietary fiber are: sweet potato coarse dietary fiber raw powder, sweet potato coarse dietary fiber superfine powder, high static pressure synergistic enzymolysis modified sweet potato coarse dietary fiber powder, extrusion Puffed sweet potato coarse dietary fiber powder, sweet potato starch, sweet potato pregelatinized starch, citrus pectin, blueberry pectin, gum arabic, rice protein, peanut protein, trehalose, salt and yeast, the mass ratio of the above raw materials is 30 in order: 25:12:8:6:10:1.5:1.5:2:1:0.6:0.5:0.4:1.5. When making bread rich in sweet potato dietary fiber, the weight ratio of the total weight of the above raw materials to water is 100:90.
