|Abstract:||In the present work, we aimed to study the influence of the partial substitution of skim milk powder for soy extract (SE) on the quality characteristics of ice cream. Physical and chemical composition, rheologic behavior, overrun value, hardness, melting characteristics, and sensory properties were evaluated at levels of 0, 10, 20, and 30% substitution. The size and distribution of the ice crystals were measured before and after heat shock testing. The addition of a SE instead of skim milk powder promoted an improvement in the protein content, pH, and consistency coefficient, and it reduced the carbohydrate content of the ice cream mix. Treatment with a 10% substitution led to the highest overrun value and to the lowest hardness value. Ice cream containing SE in the formulation exhibited a greater melting resistance, a larger amount of small ice crystals, and a lower amount of ice crystal growth after heat shock. SE could be incorporated into ice cream formulation until the substitution level of 20% devoid affects its sensory acceptance.|
