Abstract
In this paper, the innovative application of probiotics in the development of functional yogurt and its multi-dimensional influence on the quality of the final product were comprehensively studied. With the growing consumer demand for healthy foods, functional yogurt is gaining attention due to its unique health benefits. This paper first summarizes the research background, points out the important role of probiotics in yogurt and its significance for the upgrading and transformation of traditional yogurt. Then, the synergistic mechanism between probiotics and yogurt was deeply analyzed, and how probiotics improved the nutritional value and health function of yogurt during the fermentation process was discussed. In terms of the development process, the whole process from raw material selection, probiotic screening, fermentation control to post-treatment and packaging is described in detail, emphasizing the key impact of each step on the quality of functional yogurt. Especially in the screening and addition of probiotics, this paper introduces how to scientifically screen probiotic strains with specific health effects and effectively integrate them into yogurt products to maximize their health benefits. In the part of quality evaluation, this paper adopts a diversified evaluation system, including sensory evaluation, physical and chemical index analysis, microbial detection and functional component verification, etc., to comprehensively and deeply investigate the quality characteristics of functional yogurt. The results show that functional yogurt not only maintains the taste and flavor of traditional yogurt, but also significantly improves its health value and market competitiveness through well-designed development process and scientific quality control means. The research in this paper not only provides theoretical support and practical guidance for the development of functional yogurt, but also injects new vitality into the innovation and development of food industry.
