The physical (sorption isotherms at 25 °C and the glass transition temperature Tg at 0.13, 0.23 and 0.33 of water activities (aw)) and the biochemical (LC-MS, before and after drying) properties were assessed. Compared to SBMP, the results for SCMP indicated lower protein denaturation extent, lower critical aw for lactose crystallization (aw = 0.60 instead of 0.70), and lower Tg at 0.13 of aw (54.6 ± 1.4 °C instead of 57.8 ± 0.4 °C). Fitted to Guggenheim, Anderson and De Boer (GAB) model, the water sorption isotherms showed that both powders exhibited the same monolayer moisture content (Xm = 2.0 g 100 g−1, p > 0.05). These findings were linked to the absence of β-lactoglobulin, the high surface lactose content, the high initial lactose crystallization and the low size distribution (d50 < 10 μm) of SCMP.Lire moins >
