Development of a functional cake formulation with purple carrot powder dried by different methods

Abstract
In this study, it was aimed to enhanced cake formula-tion with purple carrot pow-der (PCP) dried 3 different methods (hot-air (HPC), microwave (MPC) and vac-uum (VPC) dried) and used at 5 different ratios (0, 5, 10, 15, 20%). The effects of purple carrot powder (PCP) on chemical, physical and sensory properties of cake samples were investigated. HPC substituted cake sam-ples had lower batter densi-ty and weight values. PCP usage significantly affected the crust and crumb color value of cake samples (p<0.05). Samples contain-ing MPC had higher firm-ness and lower springiness than others. Lower firmness, volume index, saturation index and higher springiness values were determined with increasing PCP rate. The highest total phenolic content and antioxidant ac-tivity were found in cake samples containing HPC and VPC, respectively. When all cake samples evaluated, the higher overall acceptability scores were obtained with HPC added cake samples at 15 and 20% substitution level compared to control sample.
