Evaluation of sensory acceptance, purchase intention and color parameters of potentially probiotic mead with Saccharomyces boulardii.

Mead is a fermented alcoholic beverage produced by yeast action on a diluted solution of honey. In this study, for the first time, sensory acceptance, purchase intention and color parameters of potentially probiotic mead with Saccharomyces boulardii were evaluated. The mead with S. boulardii presented yeast counts higher than 106 CFU/mL, being considered potentially probiotic, and tended to be yellow in color. About 160 tasters participated in the sensory evaluation, and 69.38% knew mead, but only 35.62% had tried the beverage. In terms of acceptance, the mead were within the acceptable range (above 5), and F2 (with initial soluble solids of 30° Brix and S. boulardii concentration of 0.030 g/L) was the most accepted, with an overall average of 7.63 ± 1.42 on the nine-point hedonic scale. In addition, F2 presented the highest purchase intention. In conclusion, the mead showed a tendency towards the color yellow and good sensory acceptance.

Bibliometric analysis of water kefir and milk kefir in probiotic foods from 2013 to 2022: A critical review of recent applications and prospects.

Although milk kefir and water kefir have different physical, chemical and microbiological characteristics, several microbial species that make up kefir stand out with probiotic functions. Furthermore, because it is suitable for a variety of substrates, kefir and the species of probiotic microorganisms that make it up are seen as a promising alternative in the development of probiotic and health-promoting foods. The aim of this study was to carry out a bibliometric analysis of water kefir and milk kefir in probiotic foods and to critically analyze recent applications and prospects. Using the Scopus database, 202 documents published between 2013 and 2022 were identified and submitted to bibliometric analysis using the VOSviewer software. Regarding recent applications, 107 documents published between 2021 and June 2023 were identified. It was observed that, in the literature consulted, no study used bibliometric analysis to evaluate the use of water kefir and milk kefir in probiotic foods. Due to the presence of probiotic species, kefir has been listed as an alternative for the production of new probiotic food matrices that are beneficial to health. Recent applications show kefir's potential in the development of probiotic products based on fruit and fruit juice, whey beverages, fermented milks and derivatives, and alcoholic beverages such as beers.
