[0030] The invention provides a kind of preparation method of dietary fiber, comprises the following steps:

[0031] (1) After crushing and filtering different vegetables respectively, collect the filtrate and filter residue;

[0032] (2) The filtrate and the filter residue are mixed and shaken to obtain a suspension;

[0033] (3) mixing cellulase, α-amylase and the suspension obtained in step (2), and performing enzymolysis to obtain an enzymolysis solution;

[0034] (4) inactivate the enzymolysis solution obtained in step (3), cool down, mix with pectinase and acid protease, enzymolyze, inactivate, filter, and obtain the filtrate;

[0035] (5) concentrating and drying the filtrate obtained in step (4) to obtain dietary fiber.

[0036] The invention grinds and filters different vegetables respectively, and collects filtrate and filter residue. In the present invention, the different vegetables preferably include the following components in parts by weight: 3-6 parts of asp...

Embodiment 1

[0049] A dietary fiber powder, the raw materials of which are: 600g of asparagus, 500g of celery and 500g of Chinese cabbage.

[0050] The preparation of this dietary fiber powder:

[0051] (1) Wash and cut asparagus, celery and cabbage respectively. Except for asparagus which is added with 200ml of purified water, celery and cabbage are crushed with a blender, first filtered with two layers of gauze, and then filtered with a 40-mesh nylon net for 3 hours. Collect filtrate and filter residue respectively;

Abstract

The invention belongs to the technical field of dietary fiber, and particularly relates to a preparation method of dietary fiber, dietary fiber powder and vegetable freeze-dried powder. The preparation method of the dietary fiber comprises the following steps: (1) respectively crushing and filtering different vegetables, and collecting filtrate and filter residues; (2) mixing the filtrate with thefilter residues, and performing oscillation to obtain suspension; (3) mixing cellulase, alpha-amylase and the suspension obtained in the step (2), and performing enzymolysis to obtain enzymatic hydrolysate; (4) performing enzyme deactivation and cooling on the enzymatic hydrolysate obtained in the step (3), mixing the enzymatic hydrolysate with pectinase and acid protease, and performing enzymolysis, enzyme deactivation and filtration to obtain enzymatic filtrate; and (5) concentrating and drying the enzymatic filtrate obtained in the step (4) to obtain the dietary fiber. According to the preparation method of the dietary fiber, main active substances in the dietary fiber can be reserved, no pollution is caused, and besides, the water retention capacity of the dietary fiber can be kept.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber, and in particular relates to a preparation method of dietary fiber dietary fiber powder and vegetable freeze-dried powder. Background technique [0002] Dietary fiber (DF), also known as edible cellulose, is an important food component that is not easy to be decomposed by human digestive enzymes. And the "seventh largest nutrient" after water. [0003] At present, the preparation of dietary fiber mostly adopts chemical methods (strong acid or strong alkali method) and simple water washing methods. These methods cause a great loss of the main physiologically active substances of the obtained dietary fiber and cause serious environmental pollution. Because the strong acid or strong alkali treatment in the chemical method leads to almost 100% soluble fiber, 50% to 60% of the hemifiber and 10 to 30% of the cellulose are dissolved and lost, and the dietary fiber that plays an important role in ...
