dextrin
LowTechnical / Scientific
Definition
Meaning
A soluble gummy substance, produced from starch by the action of heat, acids, or enzymes, used as a thickening agent and adhesive.
Any of a group of soluble polysaccharides produced by the partial hydrolysis of starch; used industrially as adhesives, in food processing, and in pharmaceutical preparations.

Examples
By CEFR Level
- Dextrin is often used as a food additive to thicken sauces.
- Some glues contain dextrin as a key ingredient.
- The enzymatic hydrolysis of starch yields maltodextrin, a type of dextrin with specific functional properties.

Memory Aids
Mnemonic
Think of DEXTROSE (a sugar) + 'in' -> DEXTRIN is a related carbohydrate polymer derived from starch.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "декстрин" which is a direct and correct translation.
- Be careful not to associate it with "декстроза" (dextrose/glucose), though they are chemically related.
Common Mistakes
- Mispronouncing as /dekˈstraɪn/ or /ˈdɛkstrən/.
- Confusing it with 'dextran', a different polysaccharide.
- Using it in non-technical contexts where 'glue' or 'thickener' would be appropriate.

Frequently Asked Questions
Maltodextrin is a specific type of dextrin, produced by more extensive hydrolysis. All maltodextrins are dextrins, but not all dextrins are maltodextrins.
Yes, certain types of dextrin (like maltodextrin) are Generally Recognized As Safe (GRAS) food additives used as thickeners, fillers, or sweeteners.
Dextrin is primarily derived from starch. Common sources are corn, wheat, potato, and tapioca starch.
Yes, one of the defining characteristics of dextrin is its solubility in water, unlike its parent molecule, native starch.
