Traditional analytical methods used for the measurement of grape maturity and its quality indexes have been proved to be normally sample-destructive, laborious and time-consuming, thereby limiting their utility in online/in-line quality monitoring.

Description

Grapes are one of the world’s most popular fruits both eaten fresh and processed into grape juice, sultanas and wine.

Traditional analytical methods used for the measurement of grape maturity and its quality indexes have been proved to be normally sample-destructive, laborious and time-consuming, thereby limiting their utility in online/in-line quality monitoring. Moreover, destructive analyses can be performed only on a limited number of fruit pieces and, thus, their statistical relevance could be limited.

This study evaluated the ability of lab-scale hyperspectral imaging (HYP-IM) technique for predicting the soluble solids content (SSC), total flavonoids (TF) and total anthocyanins (TA) in different table grapes varieties.

Preliminary results showed a good correlation between each of the physico-chemical parameters and the spectral information. Therefore, hyperspectral systems can be a fast and non-destructive promising technology to predict the levels of flavonoids, anthocyanins and soluble solids content of table grapes during the ripening and at harvest time.
