Starch hydrolyses during roasting under acidic conditions, and short-chained starch parts partially rebranch with α-(1,6) bonds to the degraded starch molecule. [5] See also Maillard reaction. Dextrins are white, yellow, or brown powders that are partially or fully water-soluble, yielding optically active solutions of low viscosity.
Maltodextrin can be enzymatically derived from any starch, such as corn, potato, rice or cassava. [1] [4] [5] In the United States, this starch is usually corn; in Europe, it is common to use wheat. A food starch is boiled. The resulting paste is treated with a combination of acid and enzymes to produce maltodextrins. [6]
Amylase is a key enzyme for producing dextrin. The saccharification converts dextrin into maltoses and glucose. Diverse enzymes are used in this second phase, including pullanase and other amylases.

Cyclodextrins are produced from starch by enzymatic conversion. They are used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering. [1] Cyclodextrins are composed of 5 or more α-D-glucopyranoside units linked 1->4, as in amylose (a fragment of starch).
Starch production is an isolation of starch from plant sources. It takes place in starch plants. Starch industry is a part of food processing which is using starch as a starting material for production of starch derivatives, hydrolysates, dextrins. [1] At first, the raw material for the preparation of the starch was wheat.
Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals. [1] [2] Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an additive in manufactured foods. [3]
Corn takes on myriad configurations, from the classic corn on the cob to popcorn to more processed options including corn flour and corn syrup.. How, then, do you classify such a versatile food ...
Two common examples are cellulose, a main component of the cell wall in plants, and starch, a name derived from the Anglo-Saxon stercan, meaning to stiffen. [ 2 ] To name a polysaccharide composed of a single type of monosaccharide, that is a homopolysaccharide, the ending “-ose” of the monosaccharide is replaced with “-an”. [ 3 ]
