Commercial table grapes analyzed by hyperspectral imaging and total phenolic content,total anthocyanin content and Total Soluble Solids

Table grape quality is of importance for consumers and thus for producers. Its objective quality is usually determined by destructive methods mainly based on sugar content. This study proposed to evaluate the possibility of hyperspectral imaging to characterize table grapes quality through its sugar (TSS),total flavonoid (TF),and total anthocyanin (TA) contents. Different data pre-treatments (WD,SNV,and 1st and 2nd derivative) and different methods were tested to get the best prediction models:PLS with full spectra and then Multiple Linear Regression (MLR) were realized after selecting the optimal wavelengths thanks to the regression coefficients (β-coefficients) and the Variable Importance in Projection (VIP) scores. All models were good at showing that hyperspectral imaging is a relevant method to predict sugar,total flavonoid,and total anthocyanin contents. The best predictions were obtained from optimal wavelength selection based on β-coefficients for TSS and from VIPs optimal wavelength windows using SNV pre-treatment for total flavonoid and total anthocyanin content. Thus,good prediction models were proposed in order to characterize grapes while reducing the data sets and limit the data storage to enable an industrial use

Généralités sur la provenance
This work has been made in the frame of O3VINS project to test the ability of hyperspectral imaging to predict quality attributes of table grapes.Hyperspectral imaging spectra from one side and phenolic content realized in wine maceration conditions were performed on commercial table grapes from different varieties.
