Chocolate ice cream symbiotic low calorie: multiple time-intensity analysis and preference study

Abstract

Ice cream is a widely consumed and accepted by the world population. It is very important searching for less caloric formulations, especially with reduction or absence of sucrose. The determination of the multiple time-intensity sensory profile (also denominated dynamic sensory profile) associated to the acceptance study can be relevant to guide studies and obtain information to contribute for knowledge related to the food industry, especially concerning the ingredients changes and improvement of sensorial quality. The objective of the present work was to analyse different formulations of symbiotic chocolate ice cream, one sweetened with sucrose and seven sweetened with different sweeteners (aspartame, sucralose, neotame and stevia 60%, 80%, 95% and 97% rebaudioside A, respectively) with application of multiple time-intensity analysis, study of acceptance and verification of influence about presence of inulin, L. acidophilus and sweeteners, on the physical-chemical characteristics of the product. The samples sweetened with sucrose and sucralose showed the highest acceptance, followed by stevia with 95% and 97% rebaudioside A ..The internal preference map showed the flavour importance in the samples acceptance. The sucralose was the sweetener that produced a chocolate ice-cream symbiotic and low-calorie that presented no significant difference in relation to the traditional one (sweetened with sucrose) in relation to sweetness, bitterness and milk flavour time-intensity profile as well in relation to the acceptance (p > 0.05) The samples with lower acceptance was sweetened with aspartame, neotame and stevia probably for the presence of higher intensity and duration time of bitter taste (p < 0.05). The ice cream with inulin presented slower melting rate when compared to the sample with sucrose and inulin free.
