Determination of Soluble Solids Content and Titratable Acidity of Intact Fruit and Juice of Satsuma Mandarin Using a Hand-Held near Infrared Instrument in Transmittance Mode
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.
