CaZ+ (0-60 g litre-'), glycerol (0-100 g litre-'), and non-fat dry milk solids (NFDMS, 0-140 g litre-') were combined to study their effects on the survival of Latobacillus acidophilus in controlled low-temperature vacuum dehydration and freeze-drying. A three-variable (each at three-levels) design method was used and analysed by fitting a quadratic response surface. These factors were found to be significantly effective on survival. Fitted quadratic regression equations were plotted using a graphing software package. Conditions for the best survival of freeze-drying was found to be Caz+ 5-34 g litre-'. NFDMS 100.8 g litre-', and glycerol 41.5 g litre-' and that of controlled lowtemperature vacuum dehydration was Ca2+ 5.67 g litre-', NFDMS 107.1 g litre-', and glycerol 41.0 g litre-'. Models obtained were tested using t-tests. Survival of freezing under different conditions was found to be not significantly different.
