چکیده انگلیسی
The objective of this research was to determine if adding reactive reagents to wheat starch granules before addition of alkali (the TRF method) would produce products that are different than those obtained with the conventional procedure (adding alkali before addition of reagent). Laboratory-isolated (LI) and commercial (C) normal (NWS) and waxy (WWS) wheat starches were each reacted with 6 reagents (acetic-adipic mixed anhydride (AAMA), phosphoryl chloride (POCl3), sodium trimetaphosphate (STMP), acetic anhydride (AA), succinic anhydride (SA), octenylsuccinic anhydride (OSA)). Data obtained were similar to those previously obtained with maize starches (Sui, Huber, & BeMiller, 2013). Almost no starch polymer molecule modification occurred when the TRF method and AAMA or AA were used; less than a third as much reaction when SA was the reagent used, and about the same amount of reaction when POCl3, STMP, or OSA were the reagents used (for different reasons).
