Embodiment 1

[0021] A modification method of apple dietary fiber, comprising the following steps:

[0022] 1) Take the coarse dietary fiber of the apple, crush it and pass through a 20-mesh sieve to obtain the coarse dietary fiber powder of the apple, weigh the coarse dietary fiber powder of the apple, gum arabic and water respectively;

[0023] Wherein, the quality sum of gum arabic and apple coarse dietary fiber powder is the total mass of solid materials, the addition of gum arabic accounts for 4% of the total mass of solid materials, and the addition of water is 40% of the total mass of solid materials;

[0024] 2) Mix the gum arabic and water to form a colloidal solution, then add the colloidal solution to the apple coarse dietary fiber powder, and stir well to obtain a mixed material. After standing the mixed material for 30 minutes, squeeze the Extrude under the condition that the screw speed of the machine is 450r / min, the apple dietary fiber after extrusion is dried in an electric...

After standing the mixed material for 40 minutes, squeeze the Extrude under the condition that the screw speed of the machine is 360r / min, and the extruded apple dietary fiber is dried in an electric bl...

Embodiment 3

[0031] A modification method of apple dietary fiber, comprising the following steps:

[0032] 1) Take the coarse dietary fiber of the apple, crush it and pass it through a 20-mesh sieve to obtain the coarse dietary fiber powder of the apple, weigh the coarse dietary fiber powder of the apple, sodium alginate and water;

[0033] Wherein, the mass sum of sodium alginate and apple coarse dietary fiber powder is the total mass of solid materials, the addition of sodium alginate accounts for 0.75% of the total mass of solid materials, and the addition of water is 45% of the total mass of solid materials;

[0034] 2) Thoroughly mix apple coarse dietary fiber powder, sodium alginate and water evenly to obtain a mixed material, let the mixed material stand for 50 minutes, and extrude under the condition that the screw speed of the extruder is 840r / min, after extrusion The obtained apple dietary fiber is dried in an electric blast oven at a drying temperature of 40° C., and then pulver...

Abstract

The invention discloses a method for modifying apple dietary fibers, and belongs to the technical field of food processing. The method comprises the following steps: (1) fully and uniformly mixing coarse apple dietary fiber powder, polysaccharide materials and water to obtain a mixed material, wherein the usage amount of the polysaccharide materials accounts for 0.1%-4% of the total mass of solid materials, the usage amount of the water accounts for 30%-60% of the total mass of the solid materials, and the total mass of the solid materials is equal to the mass sum of the coarse apple dietary fiber powder and the polysaccharide materials; (2) standing the obtained mixed material, extruding for modifying, drying, and grinding to obtain the modified apple dietary fibers. According to the method, the polysaccharide materials with high water holding capacity are added in the apple dietary fibers, so that a wet state of the mixed materials can be greatly improved and the yield of a product obtained when the material is extruded can be increased by 10%-50% under the circumstance that the properties remain unchanged.

Description

technical field [0001] The invention belongs to the technical field of food processing and relates to a method for modifying apple dietary fiber. Background technique [0002] Dietary fiber is known as the seventh type of nutrient for humans. Apple pomace is rich in dietary fiber and is a good raw material for preparing dietary fiber. However, the water-soluble dietary fiber content is only 3%-5%. In the dietary fiber composition, the water-soluble dietary fiber accounts for more than 10% of the total dietary fiber to become a high-quality dietary fiber. The content of water-soluble dietary fiber in the raw pomace is obviously low. Based on this standard, it is necessary to increase the content of water-soluble dietary fiber through certain modification means. [0003] Extrusion modification is a good physical modification method. Using this method to modify apple crude dietary fiber can significantly increase the content of water-soluble dietary fiber in apple crude dietar...
