TMP: transmembrane pressure; FR: feed rate (L min−1); SS: soluble solids (°brix); TA: titrable acids expressed as citric acid (%); ACN: total anthocyanin (mg L−1); : density (g mL−1). Values in the same column having the same uppercased letter for each parameter are not significantly different at a confidence level of 95%. Values in the same row having the same lowercased letter for each parameter are not significantly different at a confidence level of 95%.
