Investigating Textural and Physical Properties of Microwave-Baked Cupcake

Since the microwave technology is well considered in food processing due to the speed and mechanism, in this study, cupcake was baked at different levels of MicroWave (MW) power (۱۵۰, ۳۰۰, ۴۵۰ and ۶۰۰W) and the effects of different kinds of operational time (۳.۵, ۵, ۸, ۱۶ minutes) and power on physical properties (density, porosity, colour and height) and textural properties (crispness, hardness, cohesiveness, springiness, resilience, gumminess and chewiness) of cupcake were investigated. Results showed that the MW baking time to obtain desirable baking properties was affected by MW power. The obtained results showed that the total differences in colour from the reference batter (∆E) and colour intensity increased with increasing of MW power. Moreover, the MW cupcake baked at a power of ۶۰۰W had the least hardness, density, chewiness, gumminess values, the shortest baking time, and the highest values of cohesiveness, resilience, porosity, height, and browning index. Also, it had the highest cohesiveness, resilience, porosity, height and browning index, compared to the other powers. Therefore, the best operational power for desirable quality obtained during baking was ۶۰۰W.
