title: Rheological, physical and sensorial evaluation of cookies supplemented with dairy powders.
abstract: The effect of dairy powders (skim milk powder, butter milk powder, sodium caseinate, yoghurt powder, milk powder and colostrum powder) on cookie quality was studied. Cookies were tested for aw, calorimetric energy, diameter, thickness, spread ratio, breaking strength, colour, dough consistency and sensory evaluation. The lowest aw values were obtained for cookies containing colostrum powder; also the highest calorimetric energy values were obtained from the colostrum powder-added cookies. Diameter values of cookies with the addition of skim milk powder, butter milk powder, yoghurt powder and milk powder were higher than that of sodium caseinate and colostrum powder. The lowest spread ratio was measured in the cookie samples with added skim milk powder. The addition of yoghurt powder gave the highest breaking strength of cookies. Cookies with sodium caseinate addition exhibited the highest lightness (L*) values than the other cookies with different dairy powders. Cookies prepared with butter milk powder received the highest scores for colour, appearance, texture, crispness and overall acceptability.
