Application Note: Non-Destructive Measurements of Internal Quality Indicators for Seedless Grapes, Vitis Vinifera
25 September 2017
Sugar content is an important metric in determining proper harvest time in grapes and eating quality. To determine effectiveness and viability of the F-750 Produce Quality Meter, in measuring internal sugar content, a study was carried out sampling 270 seedless grapes. Measured values were correlated with the spectral data, and results show that the F-750 Produce Quality Meter precisely and non-destructively measures total soluble solids, with a calculated root mean square error of validation of 0.59 TSS.
