The effects of two common organic acids; lactic and acetic acids (150 mg/kg) on physicochemical properties
of native and cross-linked wheat starches were investigated prior and after gelatinization. These
acids caused formation of some cracks and spots on the granules.
The intrinsic viscosity of both starches
decreased in the presence of the acids particularly after gelatinization. Water solubility increased while
water absorption reduced after addition of the acids.
