Influence of added calcium on the rehydration behavior and processability of high-protein casein-based solutions reconstituted from micellar casein powder (MCP) and demineralized MCP
This study investigated how added calcium influences the rehydration behavior and processability of high-protein casein-based solutions prepared from native micellar casein powder (MCP) and partially demineralized micellar casein powder (d-MCP). Dispersions (10% w/w protein) were standardized to three total calcium levels (72, 74, and 77 mM) at pH 6.9 and analyzed before and after a pasteurization-mimicking treatment (72 °C, 15 s). Soluble calcium, particle size distribution, viscosity, sedimentation, and heat coagulation time were measured. Results showed that MCP strongly re-adsorbed added calcium within the colloidal calcium phosphate network, maintaining a lower content of soluble calcium, whereas d-MCP displayed higher serum calcium. Consequently, d-MCP coagulated more rapidly at equivalent calcium levels, while MCP exhibited increasing viscosity and particle growth with rising calcium. At high mineral loads, both matrices converged to short coagulation times. These findings demonstrate that mineral partitioning and micellar history govern the stability of casein dispersions and highlight critical parameters for designing high-protein dairy beverages with controlled processability.
期刊介绍:
The International Dairy Journal publishes significant advancements in dairy science and technology in the form of research articles and critical reviews that are of relevance to the broader international dairy community. Within this scope, research on the science and technology of milk and dairy products and the nutritional and health aspects of dairy foods are included; the journal pays particular attention to applied research and its interface with the dairy industry.
The journal''s coverage includes the following, where directly applicable to dairy science and technology:
• Chemistry and physico-chemical properties of milk constituents
• Microbiology, food safety, enzymology, biotechnology
• Processing and engineering
• Emulsion science, food structure, and texture
• Raw material quality and effect on relevant products
• Flavour and off-flavour development
• Technological functionality and applications of dairy ingredients
• Sensory and consumer sciences
• Nutrition and substantiation of human health implications of milk components or dairy products
International Dairy Journal does not publish papers related to milk production, animal health and other aspects of on-farm milk production unless there is a clear relationship to dairy technology, human health or final product quality.
