Names used to identify digestion-resistant maltodextrin as an ingredient in foods for regulatory purposes include soluble fiber, resistant dextrin, or dextrin. [2] [7] Names may include the food starch used to fabricate the ingredient. [4] The chemical family has had a history of changes in classification.
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).
Most of them can be detected with iodine solution, giving a red coloration; one distinguishes erythrodextrin (dextrin that colours red) and achrodextrin (giving no colour). White and yellow dextrins from starch roasted with little or no acid are called British gum. A dextrin with α-(1→4) and α-(1→6) glycosidic bonds
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]
Hydrogenated starch hydrolysates (HSHs), also known as polyglycitol syrup (INS 964), are mixtures of several sugar alcohols (a type of sugar substitute). Hydrogenated starch hydrolysates were developed by the Swedish company Lyckeby Starch in the 1960s. [1] The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia.
the right side (cecum and ascending colon), a fermenter. [73] The right side of the colon is involved in nutrient salvage so that dietary fiber, resistant starch, fat and protein are utilized by bacteria and the end-products absorbed for use by the body; the left side (transverse, descending, and sigmoid colon), affecting continence.
Icodextrin is a starch-derived, branched, water-soluble glucose polymer linked by α-(1→4) and less than 10% α-(1→6) glycosidic bonds, making it a type of dextrin. Its weight-average molecular weight is between 13,000 and 19,000 daltons and its number-average molecular weight between 5,000 and 6,500 daltons. The substance is a white to off ...
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.
