Embodiment 1

[0017] A preparation process of corn dietary fiber dry powder, comprising the following steps:

[0018] 1) Pre-treatment: remove impurities from corn husks, crush them, and pass through a 100-mesh sieve to obtain fine corn flour;

[0019] 2) Degreasing: take fine corn flour, add n-hexanol 3-5 times the volume of fine corn flour, extract at a temperature of 60°C for 0.5h, filter and separate to obtain filtrate and filter residue, and dry the filter residue to obtain degreasing material;

[0020] 3) Enzymolysis: Take the degreased material, add distilled water 20 times the volume of the degreased material, adjust the pH=5.5, add protease 2% of the weight of the degreased material, enzymolyze it under ultrasonic conditions at a temperature of 40°C for 60 minutes, filter and separate to obtain the filtrate and Filter residue: Take the filter residue, add distilled water 25 times the volume of the filter residue, adjust pH=4.5, add cellulase with 3% of the weight of the filter resi...

Embodiment 3

[0024] A preparation process of corn dietary fiber dry powder, comprising the following steps:

[0025] 1) Pre-treatment: remove impurities from corn husks, crush them, and pass through a 100-mesh sieve to obtain fine corn flour;

[0026] 2) Degreasing: Take fine corn powder, add n-hexanol three times the volume of fine corn powder, extract at a temperature of 45°C for 1 hour, filter and separate to obtain filtrate and filter residue, and dry the filter residue to obtain degreasing material;

[0027] 3) Enzymolysis: Take the degreased material, add distilled water 15 times the volume of the degreased material, adjust the pH=6.0, add protease at 3% of the weight of the degreased material, enzymolyze it under ultrasonic conditions at a temperature of 35°C for 40 minutes, filter and separate to obtain the filtrate and Filter residue: Take the filter residue, add distilled water 20 times the volume of the filter residue, adjust pH=4.8, add cellulase with 7% weight of the filter re...

Embodiment 2

[0031] A preparation process of corn dietary fiber dry powder, comprising the following steps:

[0032] 1) Pre-treatment: remove impurities from corn husks, crush them, and pass through a 100-mesh sieve to obtain fine corn flour;

[0033] 2) Degreasing: take fine corn flour, add n-hexanol three times the volume of fine corn flour, extract at a temperature of 60°C for 1.5 hours, filter and separate to obtain filtrate and filter residue, and dry the filter residue to obtain degreasing material;

[0034] 3) Enzymolysis: Take the degreased material, add distilled water 20 times the volume of the degreased material, adjust the pH=6.5, add protease at 3% of the weight of the degreased material, enzymolyze it under ultrasonic conditions at a temperature of 40°C for 60 minutes, and separate by filtration to obtain the filtrate and Filter residue: Take the filter residue, add distilled water 15 times the volume of the filter residue, adjust the pH=5.0, add cellulase with 8% of the weig...

Abstract

The invention discloses corn dietary fiber dry powder and a preparing process thereof. The process method includes the following steps of preprocessing, degreasing, enzymolysis, inactivating and dietary fiber extraction. By-product corn bran obtained after corn processing is used as a raw material for preparing the corn dietary fiber dry powder, the process is simple and easy to operate, the raw material is low in price and easy to obtain, and preparing cost is low; corn bran is turned into wealth from waste, the use ratio of the corn bran is greatly improved, and a new path is added for resource utilization of the corn bran. The dietary fiber dry powder is rich in water-soluble dietary fiber and widely applied to various food processing industries and has the effects of preventing constipation, reducing blood sugar and fat and resisting cancers.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a corn dietary fiber dry powder and a preparation process thereof. Background technique [0002] With the rapid development of the world economy and industry, people's living standards have been greatly improved, and diets have become increasingly refined. Various civilized diseases caused by overnutrition and malnutrition, such as diabetes, cardiovascular and cerebrovascular diseases, obesity, intestinal cancer, and constipation seriously affect human health. Therefore, functional foods that can regulate human body functions, prevent diseases and promote health have attracted much attention. Dietary fiber, as the seventh largest nutrient, has prominent health functions, and has gradually become a focus of attention of nutritionists. Dietary fiber can be divided into water-soluble dietary fiber and water-insoluble dietary fiber according to solubility. Diet...
