AbstractFour different formulae have been used to modify buffaloes' milk. These formulae shared the basic modifications of dilution with rennet whey, addition of sucrose and starch and fortifying with vitamins. Formula B differed from A by replacement of butter fat with liquid butter fat at 23 °C; formula C one‐third of its fat content was replaced with corn oil, while formula D was acidified with citric acid to pH 5.7 before processing. The chemical properties of formula A, B and C were nearly the same, while formula D differed considerably. The rate of peptic and tryptic digestion of the different formulae were comparable to spraydried buffalo milk.Milk powder with different formulae were stored under nitrogen for 6 months at room temperature. The samples were analysed every month for moisture, free fat, pH, solubility and wettability. The changes in these properties were slight being in the same order in formula A, B and C while formula D showed slightly greater changes. Formula A and D showed good oxidative stability, while formula B and C became oxidised in the fifth mon
