C. Thai Dextrin Co.,Ltd is a Thailand manufacturer
of dextrin powder for dyes (white, yellow and brown) , adhesives,
foundry, paper tube, paper cores, bags, corrugated boxes, paper coating,
paper sizing and adhesive for paper carton boxes.
Dextrins are a group of low-molecular-weight carbohydrates produced by
the hydrolysis of starch. Dextrins are mixtures of linear α-(1,4)-linked
D-glucose polymers. They have the same general formula as carbohydrates
but are of shorter chain length. Industrial production is generally
performed by acidic hydrolysis of potato starch. Dextrins are water
soluble, white to slightly yellow solids which are optically active.
Analytically, dextrins can be detected with iodine solution, giving a
red coloration.
DextrinThe cyclical dextrins are known as cyclodextrins. They are formed
by enzymatic degradation of starch by certain bacteria, for example
Bacillus macerans. Cyclodextrins have toroidal structures formed by 6-8
glucose residues.
Dextrins find widespread use in industry, due to their non-toxicity and
their low price. They are used as water soluble glues, as thickening
agents in food processing, and as binding agent in pharmaceuticals. In
pyrotechnics they are added to fire formulas, allowing them to solidify
as pellets or "stars." Cyclodextrins find additional use in analytical
chemistry as a matrix for the separation of hydrophobic substances, and
as excipients in pharmaceutical formulations. Not all forms of dextrin
are digestible, and indigestible dextrin is sometimes used in fiber
supplements.
For example, maltodextrin is a moderately sweet polysaccharide used as a
food additive. It is produced from starch and is usually found as a
creamy white hygroscopic powder. Maltodextrin is easily digestible,
being absorbed as rapidly as glucose. The CAS registry number of
maltodextrin is 9050-36-6.
Maltodextrin can be derived from any starch. In the US this starch is
usually corn or potato, elsewhere such as in Europe it is commonly
wheat. This is important for coeliacs since the wheat-derived
maltodextrin can contain traces of gluten.
Foods containing maltodextrin may contain traces of amino acids,
including glutamic acid as a manufacturing by-product. The amino acids
traces would be too small to have any dietary significance. |
