Abstract

Determination of soluble solids content ( SSC ) and titratable acidity ( TA ) of intact fruit and juice of satsuma mandarin was carried out using a hand-held near infrared instrument ("NIR-Gun") in transmittance mode. The resulting calibration model measured SSC in intact fruit and juice with a standard error of prediction ( SEP ) of 0.33 °Bx and 0.42 °Bx, respectively. TA measurements yielded SEP values of 0.22% and 0.14% for intact fruit and juice, respectively.
