Yogurt is a fermented dairy product of great importance worldwide because
of its nutritional and health benefits. The objective of this study was the
bioconversion of a milk-liquid whey mixture into yogurt and Aronia (Aronia
melanocarpa) supplementation. Streptococcus thermophilus and Lactobacillus
delbrueckii subsp. bulgaricus were used as microorganisms for control and
functional yogurt production. Samples were analyzed in terms of syneresis index
and textural and sensory properties throughout cold storage. The syneresis index
was determined using the drainage method, and the textural parameters were
obtained from the texture profile analysis of samples. Sensory evaluation was used
to assess consumer acceptance and responses to the sensory properties of
functional yogurt. Functional yogurt expressed differences in syneresis index
during storage and was significantly higher than control yogurt on day 21. The
textural properties of the samples were similar during storage. Higher values of
cohesiveness and springiness and lower values for hardness, adhesiveness, and
gumminess were observed in functional yogurt. The results showed that color and
taste had no statistically significant effect on yogurts. Only the level of whey
separation differed considerably on the last day of storage, according to an
evaluation of yogurt qualities. The bioconversion of liquid whey into functional
yogurt provides a technology for whey valorization that promotes human health
and environmental sustainability.
