Abstract

This project aims to evaluate the sensory profile of probiotic mead obtained through mixed fermentation with Saccharomyces cerevisiae var. boulardii and Lactobacillus casei, with an emphasis on sensory characterization using the Check-All-That-Apply (CATA) method and consumer acceptance. Mead, an alcoholic beverage fermented from honey, presents functional potential and is a promising alternative for the functional beverage market. In this regard, we propose two mead formulations to be evaluated in terms of their sensory attributes. The first formulation consists of mead obtained through mixed fermentation with S. boulardii and L. casei, while the second formulation consists of mead produced solely with S. boulardii yeast, considered the control treatment (formulation without L. casei addition). The beverage fermentation will be carried out under controlled conditions, and the resulting mead will be analyzed based on predefined terms for the CATA method, as well as for sensory acceptance by consumers. The internship at Virginia Tech, under the supervision of Prof. Dr. Renata Carneiro, will provide access to advanced infrastructure and expertise in sensory science, significantly contributing to the academic development of the scholarship student and to the advancement of research focused on the development of innovative, probiotic fermented beverages with desirable sensory characteristics.
