Abstract
|
|
|
|
RS yields and swelling powers of cross-linked RS 4 starches and effects of RS 4 starches on the pasting profiles of RS 4 added wheat starch were measured using RVA. RS yields by AOAC method were different among RS 4 starches and RS levels were higher in low swelling RS 4 starches than moderate swelling RS 4 starches. Swelling power was different with botanical source of starch and preparing procedure of RS 4 starches. The pasting curves of RS 4 added wheat starches showed increasing initial pasting temperature and lower viscosity but the patterns were similar to those of wheat starch. The pasting viscosity pattern of RS 4 added wheat starches was related with swelling power of RS 4 starch.
