Summary: Addition of low-methoxyl pectin (LMP) was found to enhance the firmness, rheology, and overall liking of low-fat set-yoghurt, while reducing whey loss. The presence of LMP increased bacterial counts, acidity, and soluble solids content in the yoghurt, contributing to higher gel strength and modulus. The microstructure analysis revealed changes in protein gel structure and cross-linking upon LMP addition, impacting the overall quality attributes of the product.

Summary: The effects of enzymatic deamidation by protein-glutaminase (PG) on skimmed set-type yoghurt were studied. The results showed that PG significantly increased the proportion of small-particle size milk protein micelles and improved the texture, rheology, microstructure, and sensory properties of the yoghurt. It also effectively inhibited post-acidification, increased water holding capacity, and improved fluidity and viscosity of the yoghurt. The sensory evaluation revealed that PG enhanced the smoothness and creaminess of the yoghurt, addressing problems of post-acidification, gel fracture, and flavors change.

Summary: The aim of this study was to investigate and compare the physicochemical characteristics and volatile flavor compounds of yoghurts made from reconstituted milk, soy drink, and oat drink. The results showed that reconstituted yoghurt had the highest titratable acidity due to its highest buffering capacity and microbial counts. Soy-based yoghurt had the highest firmness, consistency, and water holding capacity, indicating the formation of a more rigid gel. Soy-based yoghurt also demonstrated higher stability and stronger protein interactions during fermentation. Confocal laser scanning microscopy images showed that soy-based yoghurt had the densest and finest network structure, while oat-based yoghurt had a coarser and looser structure. Reconstituted yoghurt had the lightest color, while oat-based yoghurt showed more reddish and yellowish hues. The volatile flavor compounds in all yoghurts were mainly ketones, with aldehydes contributing more in soy and oat yoghurts. This study provides a theoretical basis and direction for the development of healthier plant-based yoghurts similar to dairy yoghurts.

Summary: This study evaluated the physicochemical and sensory properties of probiotic yoghurt made from reconstituted whole milk powder in aqueous fennel seed extract. The use of fennel seed extract did not affect the composition of the yogurt, but decreased acidity and increased pH. Additionally, it increased the total phenolic content and antioxidant activity of the yogurt. The survival of probiotic bacteria decreased during storage, but remained at recommended levels. Sensory evaluation showed that yogurt with 4% fennel seed extract was the most preferred.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
