Relationships between soluble calcium and soluble phosphate for milks of different concentrations. (A) Relationship between soluble calcium and soluble phosphate for the 9.6% TS (●), 19.2% TS (○), 28.8% TS (▼) and 38.4% TS (▽) milk samples that were heated at temperatures between 20 and 80 °C for 60 min. (B) Relationship between the change in soluble calcium and the change in soluble phosphate (relative to the samples held at 20 °C) for the 9.6% TS (●), 19.2% TS (○), 28.8% TS (▼) and 38.4% TS (▽) milk samples that were heated at temperatures between 20 and 80 °C for 60 min.
