Abstract

Effects of Lecithin (LC):Calcium carbonate (CaCO3) ratios (0.00:0.50, 0.10:0.40, 0.25:0.25, 0.40:0.10 and 0.50:0.00%w/w) on selected physicochemical properties and sensory acceptability of extruded breakfast cereals made with silkworm (Samia ricini D.) pupae powder and rice flour were investigated. The control sample was made without LC:CaCO3. Compared to the control, addition of LC significantly (P ≤ 0.05) reduced sectional expansion index, water solubility index and hardness, while increasing L*, bulk density and water absorption index of the samples. Increasing the CaCO3 level decreased bulk density while increased L*, ΔE*, sectional expansion index and crispness. The LC:CaCO3 interaction influenced aw, moisture, porosity and sensory liking, especially at 0.10:0.40%w/w which was suitable to produce the breakfast cereals. All samples had a protein content between 31.70% and 33.76% (dry basis), which made them qualified as a “high-protein” source. The white malt–honey flavour coating increased liking scores of the finished product compared to the uncoated ones.
