“…Panjang gelombang sensitif di daerah NIR (725.84, 731.79, 997.25nm) berperan dalam pengklasifikasian yang berkaitan dengan perbedaan komposisi kimia pada daun. Keuntungan dari penggunaan beberapa panjang gelombang dibandingkan dengan seluruh panjang gelombang dapat meningkatkan proses deteksi daun terinfeksi huanglongbing (Sankaran dan Ehsani 2011), menghemat waktu analisis (Luo et al 2012) dan meningkatkan correlation robustness (Rady dan Guyer 2015)…”

“…The presence of bruises also increases the risk of bacterial and fungal contamination, as damaged tissue is more prone to infection. 18 Avocado rot severity is dependent on both mineral concentration of the fruit and the amount of disease inoculum. 19,20 Research has shown that avocados with a lower prevalence of rots and flesh disorders are associated with higher calcium and lower potassium concentrations.…”

“…Conventionally, spectral information relating to biochemical information is generally collected from a single area on a sample using a spectrophotometer (spot or single-point assessment), which does not contain spatial information and thus limits its use for defect detection of whole horticultural produce. 12,27,28 However, the application of visible-NIR spectroscopy has proved accurate in the detection of bruised surfaces, 12 with the majority of published research and applications targeting thin-skinned fruits such as apples, 18,[29][30][31][32][33][34] tomatoes, 35 olives, 36 apricots and peaches, [37][38][39] , with only a preliminary study by Wedding et al 14 The preliminary investigations by Wedding et al 40 to detect bruises on thick-skinned 'Hass' avocado fruit at the sprung stage of ripeness (stage 2) using an NIR spectrophotometer (780-2500 nm) indicated great potential. The single-point assessment technique correctly classified more than 85% of the population based on two categories of percentage bruising -(i) ≤10%; (ii) >10% -of the area scanned after 1-2 h following fruit injury.…”

BACKGROUND A rapid non‐destructive in‐line grading system that can rapidly and accurately assess individual avocado fruit for internal quality attributes, including bruises and rots, would allow the avocado industry to provide a more consistent fruit quality to the consumer, optimise market distribution and ensure maximum yield for the producer and retailer. Fourier transform–near‐infrared (FT‐NIR) spectroscopy was investigated to detect bruises and rot susceptibility as an indication of shelf‐life in avocado fruit at both the sprung stage of ripeness and eating ripe fruit. RESULTS The classification models (principal component linear discriminant analysis, partial least squares discriminant analysis and support vector machine) for each of three growing seasons found hard green fruit that were deliberately bruised could be correctly detected with 70–78% accuracy after 2–5 h following impact damage and with 83–89% accuracy after 24 h. For eating ripe fruit, the accuracy was 60–100% after 2–5 h following impact damage and 66–100% after 24 h. The ability of the classification models to accurately predict rot development into two classes, ≤10% and >10% of flesh affected, ranged from 65% to 84% over the three growing seasons. When the rot classes were defined as ≤30% and >30% the accuracy was 69–77%. CONCLUSIONS The results of the study highlight the potential of FT‐NIR reflectance spectroscopy for application in a commercial, in‐line setting for the non‐destructive evaluation of impact damage and rot susceptibility of whole avocado fruit. The study indicates that fruit should be held for approximately 24 h prior to scanning to allow bruise development to occur, particularly in hard fruit (i.e., stage 2) prior to bruise assessment. © 2018 Society of Chemical Industry
