Doughnut is one of the high-calorie confectionary products that are popular among
consumers as a snack due to its desirable sensory properties. Thus, studies aimed to
investigate the feasibility of producing such products with lower calorie are necessary
because of the relationship between high-calorie foods consumption and overweight, and
disorders such as diabetes and cardiovascular disease. In this regard, the feasibility of
reduced-calorie doughnut production using a mixture of maltodextrin-sucralose was
investigated. The effect of maltodextrin-sucralose mixture substitution at the levels of 25, 50,
75 and 100% (w/w) was evaluated on some physical, chemical, and sensory properties. The
results revealed that the amount of oil absorption decreased significantly (p<0.05) with the
replacement of maltodextrin-sucralose mixture. Also, the replacement of the maltodextrinsucralose
mixture reduced the specific volume, porosity, and redness of the doughnut crust,
while the firmness of the crumb and the brightness of the crust increased. Finally, based on
the results obtained, producing reduced-calorie doughnut which can compete with the control
sample in terms of physical, chemical and sensory properties is feasible by replacing the
maltodextrin-sucralose mixture by 50%.
