Compared with the western developed countries, China’s research on dietary fiber in corn started relatively late, and the development is also relatively slow, for the production of dietary fiber and the production and application of dietary fiber are also in the initial stage.

At present, China’s research on dietary fiber is mainly embodied in the following aspects: First, how dietary fiber affects the human physiological function; second, the production of dietary fiber needed to use process technology; third, dietary fiber in the application of food processing research.

There is an old saying in China, called “food is the sky”, as long as there are people, it must be inseparable from the food, therefore, the development of the food industry must be the broadest, so it can be seen that the discussion of the application of corn dietary fiber in food processing is of great significance for the study of dietary fiber in China.

The composition of corn dietary fiber structure

Corn dietary fiber is mainly composed of cellulose as well as hemicellulose, of which cellulose is the most common and widespread skeletal polysaccharide in plants, cellulose constitutes the cell wall of plant cells.

Hemicellulose is mainly composed of xyloglucan, arabinoxylan, galactomannan and β(1-3,1-4)-glucan.

Characteristics of corn dietary fibre

2.1 Corn dietary fiber has the effect of lowering blood pressure

According to the composition of corn dietary fiber, we can know that corn dietary fiber is mainly polymerized by the sugar base of the macromolecule organic matter, because it contains a lot of cunning and light side chain groups, therefore, most of the dietary fibers show weak acidity.

After combining with the cations in the body, the cations will be exchanged to reduce the pH value of the digestive tract, and after the pH value is reduced, the digestive tract’s digestive function as well as the absorption function will become stronger, so it can play a role in accelerating the body’s digestion and absorption, and promote the body’s urine and fecal emissions, which will lead to a reduction in blood pressure.

Therefore, we suggest that patients with high blood pressure can eat more food containing corn dietary fiber to achieve the regulation of blood pressure and lower.

2.2 Preventing cardiovascular and cerebrovascular diseases

In addition to lowering blood pressure, dietary fiber can also play a role in the prevention of cardiovascular and cerebrovascular diseases.

Relevant medical research shows that dietary fiber can be chelated with cholesterol in the human body, and then play a role in lowering the body’s cholesterol, in addition to long-term consumption of corn dietary fiber food can also organize the reabsorption of fat and cholesterol, and then reduce the level of cholesterol in the body.

Therefore, we say that dietary fiber has a certain role in the prevention of cardiovascular disease.

2.3 Laxative function

Dietary fiber itself has a strong water holding capacity, after taking corn fiber 9 dietary foods, the food will absorb water, after absorbing water volume will become larger, which will lead to loose stools become soft, in the discharge of the time will be smoother. And long-term consumption of corn dietary fiber can promote gastrointestinal peristalsis, to achieve the function of laxative.

The application of corn dietary fiber in food processing

The source of dietary fiber is relatively wide, and the price is relatively low, so it is widely used in food processing and production, and then play a role in promoting human health.

3.1 corn dietary fiber in baked goods in the application of

Corn dietary fiber has a certain degree of water retention, the amount of water that can be absorbed is equivalent to 1.5 times its own weight, when mixed into the flour containing corn dietary fiber, the flour’s water absorption is enhanced, which in turn improves the softness of baked goods.

Therefore, we say that the taste of baked goods mixed with corn dietary fiber is much better than that of ordinary baked goods, and baked goods mixed with dietary fiber are not easy to dry and harden in the process of preservation, and will not affect the taste of the product because it is not ready to eat.

3.2 Can be used as a thickener for soups and gravies

Corn dietary fiber can be applied in the processing of baked goods, but also in the soup or gravy, and can even be used in the process of making fillings. Adding a certain amount of dietary fiber in the process of making soup can not only change the taste of the soup, but also increase the consistency of the soup itself, which in turn makes the soup look more appetizing, and adding a certain amount of corn dietary fiber in the gravy is the same reason.

In the filling can also add a certain amount of corn dietary fiber, for example, we all know that many fillings in the production of finished products in the process is very easy to produce the phenomenon of outflow, the main reason is because of the viscosity of the filling itself is relatively low, if we add a certain amount of corn dietary can increase the viscosity of the filling, so that in the process of making the finished product, the phenomenon of outflow of the filling does not occur, can both improve the appearance and improve the appearance, can also improve the appearance of the soup itself. Both can improve the appearance, but also improve the taste, but also for the body to add a certain amount of corn dietary fiber, strengthen gastrointestinal peristalsis, and play the effect of slimming and beauty.

3.3 Can be used as health food processing

In recent years, with the improvement of people’s living standards, people’s demand for quality of life is also higher and higher, in addition to maintaining a normal diet, there is a part of the people in order to increase the nutrition, will choose to take health care products, especially those who are older, we know that the dietary fiber itself has the function of lowering blood glucose, preventing cardiovascular and cerebral vascular diseases, as well as laxative function, therefore, we can be in the process of making health care products if a certain component of corn dietary fiber. Therefore, we can in the process of making health care products if a certain composition of corn dietary fiber, and then play a role in health care, improve people’s health.

In addition to the above, dietary fiber can also be used in the production of fast food, puffed food, canned food and other aspects.

Conclusion

In summary, we can find that corn dietary fiber not only has the function of lowering blood pressure, dissolving cholesterol, preventing cardiovascular disease, but also strengthen the peristalsis of the stomach and intestines to achieve the function of laxative and diuretic, but also because the dietary fiber has so many functions that make use of the development of the body’s health, so we choose to apply corn dietary fiber to the processing of food.
