F-750 Produce Quality Meter (from Felix Instruments)

Moisture content is an important indicator of quality in dried fruit, both for in-field drying and in processing center operations. The traditional method for moisture content measurement, is both destructive and time-consuming. This application note presents an alternative, non-destructive method of analysis.

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.

This application note details how the F-750 Produce Quality Meter can be used to measure sugar content (Total soluble Solids (TSS)) in Chocolate Persimmon non-destructively. The F-750 Model Builder Software was used to correlate destructive TSS reference values to non-destructive spectral data. The F-750 is shown to produce accurate TTS values throughout development and storage without damaging the fruit.

Using traditional methodology, sugar and acid content measurements are destructive and time-consuming. To determine effectiveness and viability of the F-750 Produce Quality Meter for simultaneous, non-destructive measurements of TSS and TA in blackberries, a modeling study was conducted on 75 blackberries. The results show that the F- 750 Produce Quality Meter precisely and non-destructively measures TSS and TA in blackberries, with a calculated root mean square error of prediction of 0.18 TSS and 0.05 TA.

Sugar content is an important metric in determining proper harvest time and eating quality in pears. This application note details a study in which the effectiveness and viability of the F-750 Produce Quality Meter in predicting TSS (Total Soluble Solids) in pears. It was found that the F-750 precisely predicts the internal properties of pears. The F-750 a is fast, accurate and non-destructive way to assess the internal properties of pears and helps to save time and money.

High levels of Dry Matter are positively correlated with consumer preference, and therefore harvest time should be managed to maximize Dry Matter. Historically, Dry Matter has been destructively measured, however, near Infrared (NIR) technology, utilized by the F-750 Produce Quality Meter, can nondestructively assess dry matter content. To determine the effectiveness and viability of the F-750 Produce Quality Meter in measuring Dry Matter in mangoes, a study was carried out sampling 96 Kent mangoes.

High levels of total soluble solids are positively correlated with consumer preference in citrus, and therefore harvest time should be managed to maximize total soluble solids. This application note presents a method using near infrared (NIR) technology, utilized by the F-750 Produce Quality Meter, enabling the assessment of total soluble solid content non-destructively.

Orchard harvest can be timed with peak DM content to maximize quality in apples. Sugar content is regularly measured in apples throughout development and storage. Using traditional methodology, TSS and DM content measurements are destructive and time-consuming. To determine effectiveness and viability of the F-750 Produce Quality Meter for non-destructive measurements of TSS and DM in apples, a modeling study was conducted on 40 apple cheeks.

Dry matter is an important indicator of quality in avocados, useful in estimating the harvest date and in processing center operations. The traditional method for dry matter measurement is both destructive and time-consuming. A study was conducted with the F-750 Produce Quality Meter for non-destructive measurements of dry matter in Shepard avocado, using 71 fruit for through skin calibration.

This application note details how the F-750 Produce Quality Meter can be used to measure sugar content (Total soluble Solids (TSS)) in Wax Jambu non-destructively. The F-750 Model Builder Software was used to correlate destructive TSS reference values to non-destructive spectral data. The F-750 is shown to produce accurate TTS values throughout development and storage without damaging the fruit.

The F-750 Handheld Brix & Dry Matter Meter uses near-infrared (NIR) spectroscopy to estimate quality metrics such as dry matter, Total Soluble Solids (TSS or brix), titratable acidity, and color.
