What Is Polydextrose Used For

In the food industry, it is mainly used as a low-calorie filler and sugar substitute. Unlike regular sugar, which provides 4 calories per gram, polydextrose provides only about 1 calorie per gram. It is difficult to digest in the human body, which makes it a prebiotic, which can support intestinal health without causing blood sugar spikes like refined sugar. Usually when you go to the supermarket to buy “sugar-free”, “low-carbon” or “ketogenic-friendly” products, such as protein bars, yogurt or baked goods, you can often see it in the ingredient list-after all, after the sugar and fat are removed, someone has to make up for the texture and volume of the food. Although it has received the FDA’s “generally recognized as safe” (GRAS) certification, I have to remind you that because it is a fermentable fiber, excessive intake may make some people feel bloated or have a slight laxating effect.

The Functionality Of Polydextrose

The evaluation of polydextrose in the field of food technology has always been high, which is mainly due to its unique physical properties. When you kick out the sugar or fat in the recipe, the food tends to lose its original “taste” and structure.

• Volume filling: It can effectively fill the volume blank left by the reduction of sugar, ensuring that the product maintains the expected shape and texture.
• Texture optimization: It can provide a fat-like rich taste, which is simply the soul ingredient in low-calorie dairy products and sweets.
• Stability: In addition to taste, it can also improve the shelf stability of products, prevent crystallization and water loss, and make food look less “cheap”.

Why Is It Important For People Concerned About Health?

With the change in the direction of the diet, polydextrose has become a regular in a variety of special diet programs.

• Low calorie advantage: only 1 calorie per gram, so that manufacturers can make light snacks and desserts without sacrificing flavor.
• Blood sugar friendly: Polydextrose is not metabolized like glucose, so it does not cause drastic fluctuations in insulin, which makes it the first choice for diabetics and low glycemic index dieters.
• Prebiotic effect: As the kind of carbohydrate that is difficult to digest, it can advance all the way to the colon, become a food for intestinal probiotics, and promote the balance of flora, which is indeed good for maintaining the intestinal environment.

Applications of polydextrose

If you usually have the habit of looking at the ingredient list, you should have eaten polydextrose many times, and its application range is very wide:

• Protein bars and energy bars: used to provide fiber content and support that solid chew without extra sugar.
• Yogurt and Desserts: In sugar-free pudding, mousse and yogurt, it is responsible for maintaining that silky rich texture.
• Baked goods: In biscuits and cakes that focus on “ketogenic” or “low-carbon”, it often replaces sugar to provide the skeleton structure of the food.

Safety And Digestive Problems

Although polydextrose is a safe ingredient approved by the FDA, everyone has a different “temper” for the intestines and stomach.

• Fermentation effect: Because it is a fermentable fiber, the intestinal flora will produce a certain reaction when it decomposes it. If you don’t usually eat too much fiber and suddenly eat a lot of food containing polydextrose, it may be a little trouble.
• Abdominal distension and defecation effects: The most common feedback is abdominal distension, exhaust or mild laxation. I suggest that if you are exposed to this kind of food for the first time, try a small amount first to give the intestinal tract a process of adaptation. There is no need to act too hastily.
