Abstract

The rheological behavior and density of goat milk was studied as a function of solids concentration (10.5 to 50.0%) and temperature (273 to 331 k). Newtonian behavior was observed for values of total solids (TS) between 10.5 and 22.0% and temperatures from 276 to 331 k changing to pseudoplastic behavior without yield stress for TS from 25.0 to 39.4% at the same range of temperature. Goat milk with TS between 44.3 to 50.0% and temperatures of 273 to 296 k showed yield stress in addition to pseudoplastic behavior. At 303 to 331 k the power law model was observed again, without yield stress. The density of goat milk ranged from 991.7 to 1232.4 kg.m-3.Estudou-se o comportamento reológico do leite de cabra em função da concentração (10,5 a 50,0%) e da temperatura (273 a 331 k). O comportamento Newtoniano foi obtido para valores de sólidos totais (ST) entre 10,5 e 22,0% e temperaturas entre 276 e 331 k, mudando para o comportamento pseudoplástico sem tensão residual para ST entre 25,0 e 39,4% na mesma faixa de temperatura. Leite de cabra com ST entre 44,3 e 50,0% e temperaturas entre 273 e 296 k apresentaram comportamento pseudoplástico com tensão residual. O modelo da lei da potência foi observado novamente sem tensão residual entre 303 e 331 k. Os valores experimentais de densidade do leite de cabra variaram entre 991,7 e 1232,4 kg.m-3.
