    Published 2025-03-01
    “…Increasing silverfish proportions in the composite flours was associated with decreased water absorption properties of the composite flours indicating reduced reconstitution abilities; reduced final viscosity but increased bulk density implying a high density of nutrients at lower viscosity and volume; and increased peak time indicating increased cooking energy requirements. The compressibility and Hausner ratios of the flours were high and not significantly different, indicating low flowability of the bean flour and its composites with silver fish. …”
