Tsikritzi (2011) improved the stability of medium-heat skim milk powder reconstituted at 25% TS to sterilisation at 115 °C for 15 min by addition of 0.1–0.5% DSHP or 0.1%TSC which reduced Ca2+. The heat stability of the reconstituted milk at 25% TS was much lower than that at 20% TS.Interestingly, SHMP, which also reduces Ca2+(Tsioulpaset al. 2010), caused coagulation at about 0.4% in normalmilk
