The ability of milk to foam and for the foam to be stable for some time are valuable attributes, especially in the production of cappuccino coffee. For this reason, ways of improving the foaming properties of milk have been sought.Kamath (2007) investigated the effect of adding calcium and calcium-chelating agents on the foam ability and foam stability of reconstituted low-heat skim milk powder. The milk was foamed by air injection at temperatures ranging from 5 to 85 °C. Addition of 5 or 10 mM TSC, EDTA orSHMP did not alter the foam ability (volume of foamformed) at any temperature; however, each chelating agent decreased the foam stability, particularly at the optimum foaming temperature of ~45 °C, but also at 65 °C, which is the temperature used for foaming milk for cappuccino coffee. The foam half-life was approximately halved by theaddition o f 10 mM chelating agent (see Figure 2 for addi-tion of TSC; the graphs for addition of EDTA and SHMPwere similar).
