Yet recent scientific research heralds the positive role dietary fiber plays in boosting satiety and suppressing appetite to aid weight loss or control programs. This food component has long been recognized for reducing the risk of cancer, heart disease and diabetes.
Many natural foods such as grains, cereal products, fruits and vegetables contain fiber as an integral component. Boosting the natural fiber content of baked foods and snacks with added dietary fiber offers an attractive approach for developing new products. The ingredients involved are many and varied.
The ingredients assembled in this Tech Showcase feature recent introductions and a sampling of existing products that enhance the dietary fiber content of baked foods and snacks.

It has good digestive tolerance and is stable during heat and extrusion processing.
Barliv Betafiber concentrated soluble fiber has been shown in clinical trials to reduce cholesterol when consumed as part of a diet low in saturated fat and low in cholesterol. A concentrated fiber derived from whole-grain barley, it supports the FDA-authorized claim that consumption of beta-glucans may reduce the risk of heart disease. This patent-pending product offers high purity (greater than 70% beta-glucan) and low-molecular weight, which makes it low viscosity.
Horizon Milling GrainWise wheat aleurone allows incorporation of the nutritional benefits of whole grains into processed foods. It helps preserve the pleasing sensory qualities — soft texture, high volume, mild taste and light color — that consumers enjoy in foods made with white flour. It carries 45% dietary fiber along with vitamins, minerals, antioxidants and beneficial phytochemicals.
MaizeWise corn bran boosts dietary fiber in bakery formulations at low to moderate inclusion rates. Its impact on flavor, texture, color and processing characteristics is minimal.
Oliggo-Fiber inulin acts as a bulking and masking agent that provides body and mouthfeel enhancement to foods. This soluble fiber also can be used as a fat mimetic.

Hi-maize resistant starch delivers 60% natural insoluble dietary fiber. It replaces flour while maintaining the finished product’s taste, color and familiar texture. It is fermented by beneficial bacteria within the large intestine and significantly increases short-chain fatty acids (SCFAs), including beneficial butyrate, while reducing harmful pathogens. The company also offers Hi-maize whole-grain corn flour.
NutraFlora short-chain fructooligosaccharides (sc-FOS) delivers 95% prebiotic dietary fiber and is derived from beet or cane sugar using non-GMO ingredients and a traditional natural fermentation method. It is a soft, white powder that is completely soluble in water and about 30% as sweet as sucrose. It is a gentle fiber and easily tolerated compared with other fermentable fibers. Because its short-chain structure is only consumed by beneficial bacteria, its dose is very low, making it easy to add to foods.
Purimune galactooligosaccharides (GOS) delivers 90% prebiotic galactooligosaccharides and is derived from lactose using non-GMO ingredients and a traditional natural fermentation method. It is also completely soluble in water and is 30 to 35% as sweet as sucrose. The most concentrated form of GOS commercially available, it performs well in baked foods and snacks.
Danisco USA, Inc.
Litesse polydextrose promotes digestive health. A nondigestible soluble fiber, it promotes satiety, can be used in reduced-sugar or sugar-free applications and is well-tolerated and suitable for diabetics. It carries only 1 Cal per g and comes in liquid and dry forms. Many scientific studies support its efficacy.

JustFiber comprises a line of fibers derived from white wheat, bamboo, cottonseed, sugar cane, pea, oats and potatoes. These flavorless, odorless ingredients perform consistently to reduce calories and provide 99% total dietary fiber. They contain no digestible carbohydrates and no fat. The oat fiber also comes in organic form.
Fibrex sugar beet fiber provides moisture retention and texture to bakery foods. The gluten-free fiber is a natural combination of one-third soluble and two-thirds insoluble dietary fiber. The soluble portion contributes to reducing blood cholesterol and balancing blood sugar levels while providing positive digestive benefits. An organic style is also available.
Solka-Floc powdered cellulose is highly purified cellulose backed by 85 years of use as a functional ingredient. Composed of beta-1, 4-glucan units, this ingredient is white, odorless, flavorless and comes in varying particle sizes.
