What are water-soluble dietary fibers?

1. All plants and whole grains contain dietary fiber, which is divided into water-soluble dietary fiber and insoluble dietary fiber. Insoluble dietary fiber refers to the strands and wisps in celery and beans, also known as lignin, which is not helpful to humans. Dietary fiber that is nutritious and helpful to humans specifically refers to water-soluble dietary fiber.

2. Water-soluble dietary fiber is hydrophilic, absorbs water, holds water, can be dissolved in water, and has strong water absorption, which can increase the volume of feces in the intestine, speed up the operation, reduce the time for harmful substances to contact the intestinal wall, and has good water retention and locking ability. It prevents the water in the feces from being absorbed by the human body, increases the lubrication of the feces, and transports it directly to the rectum. At the same time, water-soluble dietary fiber can slow down the speed of food from the stomach into the intestines and has the effect of absorbing water. After absorbing water, the volume increases, thereby producing a feeling of satiety and reducing energy intake, achieving weight control and weight loss. It can also prevent metabolic diseases, lower blood sugar and blood lipids, and is the nemesis of metabolic diseases.

3. Fruits such as citrus, apples, bananas, lemons, and pomegranates and vegetables such as cabbage, beets, onions, peas, and broad beans contain more water-soluble dietary fiber. The Chinese Nutrition Society proposes that each person needs to supplement 25g-30g of dietary fiber every day. People who cannot change their eating habits and are particularly deficient in dietary fiber can choose water-soluble dietary fiber granules.

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

1. Good taste.

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, thereby meeting people's taste requirements.

2. Lower calories.

As fillers and ingredients, it can effectively reduce the calories of food, avoid excessive nutrition, and meet people's requirements for low-energy food.

3. Widely used.

It has good solubility and stability and can be easily added to more foods, especially mass consumer products such as beverages, dairy products, candies, and biscuits, so that it can be widely used.

4. Many physiological effects.

It allows people to enjoy the delicious food while obtaining other more functional needs and eating healthily.

5.The price is reasonable to speed up scientific and technological innovation and achieve high quality and low price. This will not increase the cost of food too much due to the addition of dietary fiber, making it easier for food companies to accept that water-soluble dietary fiber. Polydextrose has all the above characteristics. It has a fresh taste and retains the inherent flavor of the food. It can also effectively cover up the odor caused by other ingredients that may be added to nutritious food. It has a lower calorie of 1kcal/g, does not rely on insulin metabolism, has a low glycemic index, and fully meets the low-calorie needs of diabetic people. Its high solubility and stability make it easy to be widely used in a variety of foods. It has good human tolerance and regulates blood lipids. It can be used as a prebiotic to regulate intestinal health and is a good source of dietary fiber.

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

The color should be white, and the precise control of the production process should ensure that the color of the product reaches the standard at one time to avoid artificially adding new impurities by using resin decolorization or other physical and chemical means for decolorization again.

Viscosity and hygroscopicity. Under the same conditions, the concentration of polydextrose aqueous solution is slightly higher than that of sucrose. Polydextrose powder does not have certain water absorption, which can prevent or slow down the adverse changes of foods with high water content, so that the food neither dehydrates nor absorbs water. During the production process, while ensuring the characteristics of polydextrose, the balance of polydextrose powder that does not absorb moisture under atmospheric conditions should be precisely controlled, so that it can absorb moisture without quickly absorbing moisture and clumping like other products.

High purity. Membrane separation technology is used to directly remove small sugar molecules and other impurities, so that the product can truly meet the sugar-free (national standard: refers to all monosaccharides and disaccharides content less than 0.5%) standard, and the polydextrose content can reach more than 90% , unlike using biological or chemical agents to convert glucose, avoids the production of new components.
