3.2. Evaluation of block freeze concentration assisted by centrifugation applied to fruit juices Fig. 5 shows the solids content ("Brix) of the concentrated (C) and ice fraction (Cr) at each cryoconcentration cycle from a blueberry juice (Fig. 5a), and a pineapple juice (Fig. 5b). In the cryoconcentration from a blueberry juice (Fig. 5a), the number of cycles was significant (P< 0.05) on the solids content of concentrate and frozen fractions, respectively. The feed blueberry juice was characterized by low solids content with a value of approximately 13 Brix, results from the high
