Quality characteristics of gluten-free muffins fortified with watermelon rind powder
Abstract The aim of the study was to obtain gluten-free muffin cakes for celiac patients with improved functional properties with the addition of watermelon rind. Muffins were produced by substituting the watermelon rind powder (7%, 14%, 21% and 28%) into rice flour, and some physicochemical and sensory properties of the samples were determined. With the substitution of watermelon rind powder, the protein, fat, ash, dietary fiber, Na, K, P, Mg and Ca contents of the muffins increased significantly. It was observed a decrease in the volume, volume index and spesific volume by the addition of watermelon rind powder. The L*, a* (crust and crumb) and b* values (crust) of the muffins were decreased and also b* value of the crumb of them was increased. Smaller pores and rough structure formation were detected with increasing watermelon rind powder ratio in SEM images. Moreover, it was determined that the addition of watermelon rind powder to muffins has increased the hardness, gumminess and chewiness, while the springiness was decreased. In sensory analysis, it was stated that 7% and 14% watermelon rind powder substituted muffins were liked similarly with control sample in terms of overall acceptance and other parameters.
