Too high concentration (3 g/100 mL) could negatively affect the product’s quality. Addition
of polysaccharides to milk can result in a phase separation into
a polysaccharide-enriched and casein-enriched phase if the
concentration exceeds a certain value (Tuinier, ten Grotenhuis, & de
Kruif, 2000). Consequently, gum (or hydrocolloid) and protein
concentrations need to be optimized to allow for maximum interaction between the two biopolymers. As long as the gum-toprotein concentration is not optimized, the hydrocolloide
hydrocolloid or proteineprotein interactions may predominate,
thus affecting milk reactivity (Ünal et al., 2003), which appears to
be highly dependent on gum concentration (Schmidt & Smith,
1992).
