CHANGES IN FLAVOR QUALITY OF PINEAPPLE JUICE DURING PROCESSING

摘要

The objective of the present work was to evaluate the changes in flavor attributes of pineapple juice as related to its industrial processing. Two batches of pineapple juice were collected at different processing steps: raw material, extraction, finishing, centrifugation and concentration. The samples were analyzed by qualitative descriptive analysis. Samples collected at the extraction, finishing and centrifugation steps presented similar flavor profiles among them, which indicated that there were no major changes in the juice quality during these operations. The concentrated juice was distinguished from the other samples for presenting cooked fruit aroma and flavor and a more intense artificial aroma.
