Micronization of lentil modified starch- and protein-related properties. Approximately 2.5 to 5.6% of the starch was gelatinized following micronization. Differential scanning calorimetry (DSC) results showed a 13 to 40% decrease in heat enthalpy, and viscosity analysis (Rapid Visco Analyzer) showed a 21 to 55% increase in peak viscosity and a 1 to 3 °C reduction in pasting temperature. Nitrogen solubility decreased across the pH range of 2 to 9, and lipoxygenase activity was reduced by 100-fold. There was a 25 to 43% increase in water holding capacity with no change in oil absorption capacity. The colour intensity of the pigments in the green and red lentil were reduced upon micronization of seed, and the particle size of flour was lowered with 7 to 13% more flour passing into the finest (en-USGelatinizationFunctional propertiesSensory analysisProteinStarchFlourtext
