Abstract
In this study, the effect of palm kernel powder (PKP), a vegetable waste, on the quality parameters of bread and dough was investigated. For this purpose, farinograph and extensograph values of doughs made from PKP-flour (2.5, 5, 7.5 and 10%) mixed flours were investigated. Weight, volume, specific volume, crust color, inner color and firmness values were investigated in bread made from mixed flour. The results showed that the water absorption, development time, stability, resistance to extension and maximum resistance values of the dough increased with the increase in the amount of PKP. It also decreased in degree of softening, extensibility and energy levels. The change in softening degree and stability values were found to be statistically significant (p<0.05). PKP additive caused a firmer structure in bread samples. It was observed that the weight, volume, specific volume, first-day hardness and third-day hardness values of the bread increased with the increase in PKP. L* and a* values of bread crust color and inner color decreased with the addition of PKP. The increase in PKP had a positive effect on bread quality by increasing dough stability and bread volume values.
