Development and Role of Resistant Dextrin Fiber in Inhibiting Fat Absorption

1. Development of resistant dextrin fiber

Resistant dextrin is a water-soluble dietary fiber derived from corn starch introduced in Japan in 1988. 50% of the resistant dextrin fiber will not be digested and absorbed by the human body, which is called "indigestible dextrin", also known as "resistant dextrin".

Dietary fiber is known as the seventh largest nutrient in the human body. It has satiety, low glycemic index, and can help clean the intestines. At present, many beverages add dietary fiber such as resistant dextrin.

The substance has been certified by the US GRAS as early as 1990. In 1992, 1994 and 1998, it also obtained the efficacy certification of Japan's designated health food system for adjusting the intestines, delaying the rise of postprandial blood sugar, and delaying the rise of postprandial triglycerides. In 2012, it was approved as a common food by the Chinese Ministry of Health, and its Chinese name is Fibersol-2. In 2018, the US FDA included several types of fibers, including resistant dextrin, on dietary nutrition labels after a two-year investigation.

Coca-Cola launched its "diet cola" in Japan in 2017, Coke Cola plus, which contains Fibersol-2. The product does not contain any sugar and calories. To further appeal to body shapers, in addition to 0 calories, it also inhibits the amount of fat absorbed in the body after meals.

2. The role of resistant dextrin

(1) Weight control and fat loss

Resistant dextrin, a low molecular weight water-soluble dietary fiber, can significantly reduce blood cholesterol and the risk of atherosclerosis. Continuous intake can also reduce serum cholesterol and neutral fat concentration and body fat mass, and can also adsorb bile acids, fats, etc. to reduce the absorption rate, reduce blood lipids, and improve lipid metabolism in patients with various types of hyperlipidemia , so as to achieve the effect of weight control and fat loss.

(2) Meal replacement

Resistant dextrin is an indigestible dietary fiber that absorbs water and swells, making people feel full and helping to delay the recurrence of hunger, thereby reducing food intake and completely replacing meals.

(3) Relieve constipation

Unlike standard starches, and like resistant starches,resistant dextrins like tapioca dextrin, and maltodextrin powder bulk are actually hydrolyzed in the upper part of the digestive tract. Only 15% is enzymatically digested in the small intestine, while the rest enters the large intestine. 75% of the initial amount is slowly and gradually fermented in the large intestine, and 10% is excreted from the body, increasing the volume of the stool and softening the stool, thereby achieving the effect of improving constipation.
