The study evaluated the impact of three yeast strains (Saccharomyces cerevisiae, probiotic Saccharomyces cerevisiae var. boulardii, and probiotic Kluyveromyces marxianus var. lactis) on the physicochemical, microbiological, textural, and nutritional properties of ice cream. Statistical analysis using ANOVA revealed that yeast inoculation significantly affected (p < 0.05) the product characteristics. S. cerevisiae led to the lowest first drip (20.78 s), complete melting time (86.78 s), overrun (44.80%), firmness (13.71 g), consistency (251.21 g s), and pH (6.30). Microbiological analysis immediately after production showed that S. boulardii exhibited the highest initial viability (8.05 log cfu/g), exceeding the probiotic threshold, while S. cerevisiae and K. lactis achieved 7.09 and 6.16 log cfu/g, respectively. Regarding nutritional profiles, S. cerevisiae significantly increased formic, malic, and lactic acids, and resulted in the highest saturated fatty acid content (78.48%). S. boulardii and K. lactis also modified the fatty acid and organic acid profiles, demonstrating strain-dependent metabolic effects, although they generally produced milder physical alterations than S. cerevisiae. In conclusion, inoculating ice cream with these yeasts, particularly S. boulardii, successfully enhances its functional and nutritional value, offering a highly practical and promising technological approach for the dairy industry to develop novel, health-promoting functional desserts.
