Non-Destructive Determination of Quality Traits of Cashew Apples (Anacardium Occidentale, L.) Using a Portable near Infrared Spectrophotometer

Abstract

The prediction of cashew apple quality by non-destructive analysis using a portable (100 g), near infrared spectrophotometer has been investigated. The quality parameters of interest were: soluble solids content (SSC), titratable acidity (TA), SSC/TA ratio and ascorbic acid (AA). Partial least squares calibration models were developed using the spectral range from 950 nm to 1600 nm available with the portable spectrophotometer, with a spectral resolution of 10 nm. The model was validated using an independent set of samples. Validation results gave root mean square error of prediction values of 0.6%, 0.04%, 2.7 and 27 mg 100 mL -1 for SSC, TA, SSC/TA and AA, respectively.According to the results, this highly portable spectrometer can be used to monitor and control cashew apple postharvest quality, and may constitute an important tool for genome wide selection in cashew breeding programmes.

Review: NIR Spectroscopy as a Suitable Tool for the Investigation of the Horticultural Field

“…The chemical and physical parameters that define intrinsic quality are often determined simultaneously thanks to the use of multicomponent calibrations. For this reason, various works report both data relating to direct index measurements (quantitative parameters) and indirect indices (pH, titratable acidity, texture characteristics, and sensory parameters) [40-63]: They are reported in Table 1 with the same legend group (P) [30,128,[146][147][148][149][150][151][152]. In order to get an idea of the predictive ability of a model, a number of statistical measures were used.…”

Metabolomic Variability of Different Genotypes of Cashew by LC-Ms and Correlation with Near-Infrared Spectroscopy as a Tool for Fast Phenotyping

“…The cashew nut consists of nut kernels that are edible and commercially known as cashew nuts. This complete fruit forms on the distal end of the false fruit that is also edible (called cashew apple or peduncle) [2]. Cashew nut (kernel) is the main product of this crop marketed globally.…”

GGE biplot for stability and adaptability in cashew tree clones

“…There are several initiatives of the plant breeding research involving cashews, whose efforts require viable tools to evaluation, with agility and employing representative sampling, the main characteristics of fruit quality of cashew, helping the programs of selection of cultivars (RIBEIRO et al, 2016).…”

“…Há diversas iniciativas de pesquisas envolvendo o cajueiro, cujos esforços exigem ferramentas viáveis para avaliar, com agilidade e empregando amostragem representativa, as principais características de qualidade dos frutos de caju, ajudando os programas de seleção de cultivares (RIBEIRO et al, 2016).…”
