Soluble Solids and Simple Sugars Measurement in Intact Mango Using Near Infrared Spectroscopy

Abstract

<jats:p>A rapid, reliable, and nondestructive method for quality evaluation of mango (<jats:italic>Magnifera indica</jats:italic>) fruit is important to the mango industry for international trade. The objective of this study was to determine the potential of near-infrared (NIR) spectroscopy to predict soluble solids content (SSC) and individual and combined concentrations of sucrose, glucose, and fructose nondestructively in mango. Mature mangoes at two different temperatures (15 °C and 20 °C) were measured by NIR interactance (750–1088 nm wavelength region analyzed) over an 11-day period, starting when the fruit were underripe and extending to a few days past optimal ripeness. Partial least squares regression was used to develop models for SSC, individual sugar concentration, and the sum of the concentrations of the three sugars. Such analyses yielded calibration equations with <jats:italic>R</jats:italic><jats:sup>2</jats:sup> = 0.77 to 0.88 (SSC), 0.75 (sucrose), 0.67 (glucose), 0.70 (fructose), and 0.82 (sum); standard error of calibration = 0.56 to 0.90 (SSC), 10.0 (sucrose), 0.9 (glucose), 4.5 (fructose), and 10.4 (sum); and standard error of cross-validation = 0.93 to 1.10 (SSC), 15.6 (sucrose), 1.4 (glucose), 6.9 (fructose), and 16.8 (sum). When the SSC calibration was applied to a separate validation set, the standard error of performance ranged from 0.94% to 1.72%. These results suggest that for assessment of mango ripeness, NIR SSC calibrations are superior to the NIR calibrations for any of the individual sugars. This nondestructive technology can be used in the screening and grading of mangoes and in quality evaluation at wholesale and retail levels.</jats:p>

Dissecting genomic hotspots underlying seed protein, oil, and sucrose content in an interspecific mapping population of soybean using high‐density linkage mapping

“…The results reported by the authors indicated that NIR provides an efficient and alternative method and the results are comparable with other platforms the chemical reference methods (Brenna and Berardo, 2004;Cozzolino, 2015;Moncada et al, 2013). Delwiche et al (2008) developed the NIR equation and determined the potential of NIR to predict sucrose, glucose, and fructose content in mango with high precision. To confirm the reliability of NIR-generated phenotypic data, we performed QTL analysis using these data sets that are reported in the other sections of the manuscript.…”

“…The HPLC (high-performance liquid chromatography) platform is considered more reliable for sucrose content analysis due to its accuracy; however, this platform has limitations to use for high-throughput assay and also involved higher costs per sample. Additionally, these wet-laboratory techniques are associated with completeness of the extraction and the stability of the extracted compound during extraction steps, and hence, analysing these compounds in native matrix would be useful (Berardo et al, 2009;Brenna and Berardo, 2004;Delwiche et al, 2008). Considering these factors, a subset of 100 RILs was selected from the RIL mapping population.…”

“…The level of dissolved sugars (sucrose, glucose and fructose) in fruit juice is generally measured as TSS using a refractometer (Delwiche et al 2008). TSS values in the present study were considered as an index of sugar content.…”

Cold storage of ‘Palmer’ mangoes sorted based on dry matter content using portable near infrared (VIS-NIR) spectrometer

“…Nondestructive methods have long been suggested as a means to evaluate fruit quality and near infrared spectroscopy (NIRS) is one of the analytical techniques that stand out (Abbott, ). Therefore, many studies can be found with bench top and/or on‐line NIR spectrometers estimating soluble solids content (SSC), dry matter content (DM), titratable acidity (TA), firmness, starch content, and other quality parameters in mango fruit (Delwiche, Mekwatanakarn, & Wang, ; Mahayothee, Leitenberger, Neidhart, Mühlbauer, & Carle, ; Nicolaï et al, ; Saranwong, Sornsrivichai, & Kawano, ; Schmilovitch, Mizrach, Hoffman, Egozi, & Fuchs, ; Valente, Leardi, Self, Luciano, & Pain, ).…”
