The polymer main chain consists of α-1,6 glycosidic linkages between glucose monomers, with branches from α-1,3 linkages. This characteristic branching distinguishes a dextran from a dextrin, which is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages. [2]
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]
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.
A separate study found a slight difference in urban areas with [clarification needed] elderly who did not own a car. [21] Aside from transportation, the kind and quality of available food can also shape food choices if a person lives in a so-called "food desert". Social network type can also affect individuals' food choices in our elderly ...
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 ...
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
Nevertheless, a fibre supplement may be needed to prevent constipation when fibre intake via food is low, which is the case among many inactive elderly people. A cereal bran such as psyllium seed husk , or a synthetic fiber such as methylcellulose is often used in this case.
