3.2. Evaluation of block freeze concentration assisted by centrifugation
applied to fruit juices
Fig. 5 shows the solids content (°Brix) of the concentrated (Cs) and
ice fraction (Cf) 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 b 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
