The starch in pseudocereals has small granules and low amylose content (except for buckwheat), which gives it similar properties to waxy-type cereal starches. [2] The functional properties of pseudocereals, such as high viscosity, water-binding capacity, swelling capability, and freeze-thaw stability, are determined by their starch properties ...
Fiber properties—built in (natural) properties [ edit ] In terms of performance, wool has been advertised as a "miracle fabric" [ 38 ] [ 64 ] [ 65 ] as it naturally possesses a variety of functional properties, including stretch, warmth, water absorption, flame retardance, and the ability to wick away body moisture.
Resistant starch is considered both a dietary fiber and a functional fiber, depending on whether it is naturally in foods or added. [51] [52] [53] Although the U.S. Institute of Medicine has defined total fiber as equal to functional fiber plus dietary fiber, [54] U.S. food labeling does not distinguish between them. [55]
Raw starch granules resist digestion by human enzymes and do not break down into glucose in the small intestine - they reach the large intestine instead and function as prebiotic dietary fiber. [46] When starch granules are fully gelatinized and cooked, the starch becomes easily digestible and releases glucose quickly within the small intestine.
Glycogen is analogous to starch, a glucose polymer in plants, and is sometimes referred to as animal starch, [16] having a similar structure to amylopectin but more extensively branched and compact than starch. Glycogen is a polymer of α(1→4) glycosidic bonds linked with α(1→6)-linked branches.
The major sources of amylopectin of starch intake worldwide are the cereals such as rice, wheat, and maize, and the root vegetables potatoes and cassava. [25] Upon cooking, amylopectin in the starch is transformed into readily accessible glucose chains with very different nutritional and functional properties. [26]

Starch: Starch is an inexpensive biodegradable biopolymer and copious in supply. Nanofibers and microfibers can be added to the polymer matrix to increase the mechanical properties of starch improving elasticity and strength. Without the fibers, starch has poor mechanical properties due to its sensitivity to moisture.
