“…Many food products contain air bubbles, for example whipped cream, beer, bread, ice cream, mousse, and aerated chocolate (Campbell & Mougeot 1999), and these products may destabilise due to drainage, Ostwald ripening, or coalescence, of which the latter is the least understood destabilisation mechanism (Langevin 2015). Although microfluidics have been used to produce and study foams (Huerre et al 2014), only few foams with food-grade ingredients were produced with microfluidics (Ahmad et al 2012;Wang et al 2010), and microfluidic research on coalescence stability of bubbles is limited (Fu et al 2015;Wu et al 2014;Yang et al 2012).…”
