The Nand C-terminal segments of bovine αs1-caseinB (f1-23 and f136-196) were characterized under conditions that promoted or inhibited self-association to determine the relative contributions of each fragment to the interaction of αs1-casein with itself or with other caseins. In earlier studies of f1-23, nuclear magnetic resonance (NMR) data and circular dichroism (CD) spectra showed that its c...

We describe in this study the aggregation behaviour of β-casein micelles from milk bulk aqueous solution as function both temperature and calcium content, its influence on foaming properties, order to test if different states makes possible design proteins-based thermoresponsive foams. First, we characterized morphology self-assembled molecules by coupling turbidity measurements, Dynamic Light ...

The monthly variation in raw dairy silo milk was investigated and related to the ripening time of resulting cheese during an industrial cheese-making trial. Milk composition varied with month, fat protein content being lowest August (4.19 3.44 g/100 g, respectively). Casein micelle size largest (192–200 nm) December–February smallest (80 August. In addition, SCC, total bacteria count, proteolyt...
