Abstract
The homemade ice cream formulations produced from the partial replacement of dairy fat with unripe banana biomass (UBB) were elaborated and characterized. Formulations 1, 2 and 3 with 2.6%, 12.5% and 21.9% of reconstituted UBB, respectively in partial replacement of heavy cream were compared to the traditional formulation (0% UBB and 100% of heavy cream). The characterization included: physicochemical, microbiological, and sensory analyses. Fat reduction of at least 22.6% in centesimal composition were noticed among the formulation with UBB (p < 0.05). The titratable acidity and meltdown rate of the formulations increased with the addition of UBB and fat reduction. The sensory analysis showed that the preference of the panellists reduced with substitution of cream for UBB. The traditional formulation and formulation 1 were the most preferred. There was no difference in the attributes of overall impression, appearance, creamy texture, color, sweet taste and vanilla flavor between the traditional formulation and formulation 1 in the acceptance test. It was also found that the intention to consume those same formulations was positive. Therefore, the production of ice cream using prebiotic fat replacers are an interesting option to be explored in an attempt to combine sensory acceptance with health benefits.
