F-750 Produce Quality Meter precisely, simultaneously, and non-destructively measures the TSS of wax apple

Sugar (TSS or ºBrix) content is regularly measured in wax apple or jambu, Syzygium samarangense, throughout development and storage. Using traditional methodology, TSS measurements are destructive and time consuming. To determine effectiveness and viability of the F-750 Produce Quality Meter, Felix Instruments, for non-destructive measurements of TSS in wax apple, a modeling study was conducted. Results show that the F-750 Produce Quality Meter precisely, simultaneously, and non-destructively measures the TSS of wax apple. A strong correlation between spectral data and collected reference values is illustrated by a model prediction R2 of 0.98 for TSS. Figure 2, se "More information" displays this correlation and demonstrates the consistency of measurement.A calculated Root Mean Square Error of Prediction (RMSEP) of 0.46 TSS further illustrates the accuracy of the created model. This RMSEP value indicates the average uncertainty for a given measurement when the model is loaded onto the F-750 and used to predict TSS. The RMSEP is equivalent to the expected uncertainty within 68% of all predictions.More informationSourceFelix Instruments Newsletter, July 2016
