Leite condensado: comparação entre o processo tradicional e empregando pré-concentração por membranas

Abstract

Condensed milk is a product that presents the highest growth in production in Brazil, favoring the development of new technologies and the adaptation by industries small and medium sized for manufacturing this product. The main objective of this study was to evaluate the attributes of two different manufacturing processes, the first using standardized milk with approximately 12 % total solids and milk pre-concentrated by reverse osmosis the second, identifying the difference between the products and impact for process the membrane concentration in their desirable characteristics. The experiments were conducted in an industry in the Zona da Mata Mineira, with assessments physicochemical and sensory. The products were analyzed with 1, 30, 60 and 120 days of manufacture. It was concluded that the condensed milk with osmosis had no difference statistically significant compared to the condensed milk without osmosis about the attributes evaluated and it was possible to establish relationships between constituents, with practical purpose, such as analytical references like minimum soluble solids content to obtain the minimum viscosity.
