Microbiological analyses have been made of the coliforms, 45ºC, 30ºC and presence of Salmonella sp. to check the quality of the product. The model adopted for the sensory analysis was the preference ordering test, for comparison of yogurt in its various concentrations of pulp. Microbiological analyses found in the concentrations of the yogurts, 20% 30% and 40% of pulp were satisfactory in accordance with the legislation in force for that product type.
