Dietary fiber, known as intestinal scavenger, is the nemesis of metabolic diseases. It helps to relieve constipation, help lose weight, lower blood sugar, and lower blood fat. Which foods are rich in dietary fiber? Citrus, apples, bananas, lemons, pomegranates and cabbage, beets, onions, alfalfa, peas, and broad beans contain much water-soluble dietary fiber. A high-quality, market-oriented dietary fiber generally has the characteristics of good taste, low calories, wide application, multiple functions, and reasonable price. Let’s learn more about water-soluble dietary fiber in detail below.

What are the water-soluble dietary fibers?

1. All plants and whole grains contain dietary fiber. Dietary fiber is divided into water-soluble dietary fiber and water-insoluble dietary fiber. Insoluble dietary fiber refers to the strands and wisps of celery and beans, also known as lignin, which is of no help to humans. The dietary fiber that is nutritious and helpful to humans.

2. Water-soluble dietary fiber is rhydrophilic, absorbs water, holds water, can be dissolved in water, has stong water absorption, increases the volume of feces in the intestinal tract, speeds up the operation speed, and reduces the time for harmful substances to contact the intestinal wall. The moisture in the feces is not absorbed by the body, which increases the lubricity of the feces and is directly transported to the rectum. At the same time, water-soluble dietary fiber can slow down the speed of food entering the intestinal tract from the stomach and has a water-absorbing effect. After absorbing water, the volume increases, thereby producing a feeling of fullness and reducing energy intake, thereby achieving the effects of weight control and weight loss. It can also prevent metabolic diseases, lower blood sugar and blood fat, and is the nemesis of metabolic diseases.

3. Citrus, apples, bananas, lemons, pomegranates and other fruits and vegetables such as cabbage, beets, onions, alfalfa, peas, and broad beans contain much water-soluble dietary fiber. According to the Chinese Nutrition Society, each person needs to supplement 25g-30g of dietary fiber per day. People who cannot change dietary habits or urgently need to supplement dietary fiber can choose water-soluble dietary fiber particles.

How to choose high-quality water-soluble dietary fiber powder?

A high-quality, marketable dietary fiber should have at least the following five characteristics:

1. Good taste.

The dietary fiber itself should have a mild taste, so that the original taste of the food will not be affected by the addition of dietary fiber, and so as to meet people's requirements for taste.

2. Lower heat.

As a filler and ingredient, the dietary fiber can effectively reduce the calories of food, avoid overnutrition, and meet people's requirements for low-energy food.

3. Wide range of applications.

With good solubility and stability, the dietary fiber can be easily added to more foods, especially in mass consumer goods such as beverages, dairy products, candies, and biscuits, so that it can be widely used.

4. Many physiological effects.

The dietary fiber can make people enjoy the delicious food while obtaining other more functional needs and stay healthy.

Water-soluble dietary fiber - polydextrose has all the above characteristics, tastes fresh, and retains the inherent flavor of the food. It can also effectively cover the peculiar smell that may be caused by adding soybeans, vitamins, minerals and other ingredients in nutritious foods. It has lower calorie 1kcal/g, independent of insulin metabolism, low glycemic index, and can fully meet the energy needs of low-calorie and diabetic foods. The high solubility and stability make it easy to be widely used in a variety of foods. It has good human tolerance and blood lipid regulation function, and as a prebiotic to regulate intestinal health and other physiological functions, it is a good source of dietary fiber.

High-quality water-soluble dietary fiber should also have the following characteristics.

1. The color.

The color should be pure white, and the precise control of the production process should meet the product color standard at one time, avoiding the use of resin decolorization or other physical and chemical means to decolorize and artificially adding new impurities.

2. Viscosity and hygroscopicity.

Under the same conditions, the concentration of polydextrose aqueous solution is slightly higher than that of sucrose. Polydextrose powder has a certain degree of water absorption, which can prevent or slow down the adverse changes of foods with high water content, so that foods are neither dehydrated nor absorb water. During the production process, under the condition of ensuring the characteristics of polydextrose, the balance of moisture absorption of polydextrose powder under atmospheric conditions should be precisely controlled, so that it can absorb moisture without quickly absorbing moisture and agglomerating like other products.

3. High purity.

Using membrane separation technology to directly remove small sugar molecules and other impurities, so that the product can truly reach the standard of sugar-free (national standard: refers to the content of all monosaccharides and disaccharides less than 0.5%), and the content of polydextrose can reach more than 99%. , unlike the conversion of glucose by biological or chemical agents, avoiding the production of new components.
