Embodiment 1

[0053] An extruded corn flour with high cellulose content comprises raw material components and the mass parts of each raw material respectively: 99 parts of corn flour and 1 part of cellulose.

[0054] A preparation method of puffed corn flour with high cellulose content, comprising the following steps:

[0055] Step 1, pretreatment of raw materials

[0056] drying the corn flour at 45°C for more than 24 hours to obtain dried corn flour;

[0057] Step 2, Formulate High Cellulose Corn Slurry

[0058] According to the proportioning ratio, weigh the raw material of corn puffed powder with high cellulose content, add water, and mix evenly to obtain corn slurry with high cellulose content; wherein, the water content of the corn slurry with high cellulose content is 23%;

[0059] Step 3, extrusion puffing

[0060] The mixed slurry is placed in a twin-screw co-rotating extrusion extruder for extrusion and expansion to obtain extruded and expanded corn powder with high cellulose c...

Abstract

A high-cellulose-content puffed corn powder and a preparation method thereof belong to the technical field of food deep processing. The high-cellulose-content puffed corn flour includes raw material components and their mass parts respectively: 85-99 parts of corn flour, and 1-15 parts of cellulose. The preparation method is as follows: drying the corn flour; weighing the raw material of corn puffed flour with high cellulose content according to the proportion, adding water, and mixing uniformly to obtain a high cellulose content corn slurry with a water content of 20-25%; The slurry is extruded and extruded in a twin-screw co-rotating extrusion extruder. The length-to-diameter ratio of the die head and die opening is 55-64, the extrusion temperature is 60-140°C, and the screw speed is 100-200rpm. The expanded corn powder with high cellulose content is dried, pulverized and sieved to obtain the expanded corn powder with high cellulose content. The method solves the problem of poor expansibility when adding cellulose to corn flour to prepare puffed corn flour with high cellulose content.

Description

technical field [0001] The invention relates to the technical field of food deep processing, in particular to puffed corn flour with high cellulose content and a preparation method thereof. Background technique [0002] Corn is the cereal crop with the largest output in the world. It has various processing methods, a wide variety of products, rich nutrition, wide range of uses and high added value. Based on the improvement of people's living standards, it is particularly important to study additional corn products that are more conducive to a healthy diet. In corn flour, carbohydrates account for about 75% (especially rich in starch). [0003] Some existing evidence can show that dietary fiber intake can affect intestinal peristalsis, fiber intake is inversely related to body weight and body fat, which can help weight loss, and studies have shown that dietary fiber can prevent the body by binding nutrients. The absorption of the gastrointestinal tract can promote the produ...
