In the present work, the physicochemical characterization (total soluble solids (TSS), hydrogenation potential (pH), total titratable acidity (ATT), ratio (RATIO) Brix / titratable total acidity, ascorbic acid and moisture) (Coliformes at 35 ° C and 45 ° C, Molds and Yeasts, Staphylococcus coagulase Brazilian Journal of Development Braz. 16508 806 S.P.M.

These parameters were studied on both industrial scale and laboratory scale to investigate possible interference in large scale production. It was verified that the physicochemical properties of both the pulp and the concentrate were in accordance with the current legislation, regardless of the scale studied. However, these properties did not show uniformity when the scale of study was modified. Microbiological testing of pineapple samples was in accordance with the limits laid down by legislation and was considered satisfactory from the point of view of overall product quality.
