Chasing the chill: Unveiling the dynamic flavors and textures of ice cream formulations

Summary

In this study, nine commercial ice creams and four prototypes were assessed. For the sensory analysis, quantitative descriptive analysis (QDA), and temporal dominance of sensations (TDS) methodology were used. According to the QDA results, full-composition ice cream showed significantly higher differences (p < .05) in terms such as vanilla and sweet flavors, brightness, creamy texture and appearance, and viscosity, exhibiting longer melting times. Functional ice creams showed significantly higher differences (p < .05) in terms like viscosity, creamy texture, and appearance. On the other hand, agave fructans in prototype ice creams were found to be able to reduce fat, but not fat and sugar simultaneously, showing a significant decrease (p < .05) in terms such as hardness, crystallized texture, gummy texture, and porosity. Based on the PCA results, the analysis accounted for 75.28% of data variability. Full-composition ice creams and one functional ice cream were related to terms such as viscosity, fatty sensation, creamy texture and appearance, dense, gummy, among others. The rest of the commercial ice creams were related to vanilla and caramel flavor and smell, artificial aftertaste, aerated, porosity, among others. Prototype ice creams were related to hard texture, salty and milk flavor, and crystallized texture. Based on the results of the TDS method, all formulations were found to be significantly dominant (5%) in terms such as vanilla flavor and sweet flavor at the beginning of the test. Formulations containing butyric fat and/or vegetable fat, or agave fructans were significantly dominant (5%) in fatty sensation.
