About this supplement

Soluble Corn Fiber (SCF) is a type of soluble, non-digestible carbohydrate derived from corn starch through enzymatic or chemical processing. It is classified as a resistant maltodextrin or resistant dextrin, meaning it resists digestion in the small intestine and is fermented in the colon by gut microbiota. SCF functions as a prebiotic fiber, promoting the growth of beneficial bacteria, and contributes to increased fecal bulk. It is widely used as a dietary fiber supplement and functional food ingredient to boost fiber content without significantly affecting taste, texture, or viscosity. It is generally recognized as safe (GRAS) by the FDA.

Technical details â–¼

Chemical ID (CAS)

9004-53-9 (for dextrins generally)

Physical properties

Typically a white to off-white powder or granular solid. Highly soluble in water, forming clear, low-viscosity solutions. Hygroscopic (absorbs moisture from air). Tasteless and odorless.

How it’s made

Produced from corn starch via enzymatic hydrolysis and/or heat treatment (pyrolysis), followed by enzymatic rearrangement (transglucosidation) to create indigestible alpha-1,2 and alpha-1,3 glycosidic linkages that resist human digestive enzymes.
