Arginine has been reported as a maturity gauge (Jackson and Lombard, 1993). A decline in arginine may signal maturation.

What is the anthocyanin in grape juice?
In the grape juice industry and in other fruit juice industries (berry processing), skin or peel of the fruit waste is rich in anthocyanins. Therefore, after juice extraction the pressed residue containing peels (skin) and seeds can be further processed to obtain value-added products. Anthocyanins can be recovered from grape skin using acidic methanol or water as extraction solvent. Enzyme application before extraction can enhance the extraction efficiency of such pigments. The production of anthocyanin-rich extracts from the residue of the vinification of three Vitis vinifera grape varieties (Cabernet Sauvignon, Ribier, and Carmenere) has been reported. The method involved the addition of an active pectolytic enzyme preparation in an aqueous medium, which resulted in reduced time required for maceration, setting, and filtration. Enzymatic complexes studied were Pectinex BE3-L (pectinesterase, pectinlyase, hemicellulase, and cellulase from Aspergillus niger ), Vinozyme C (pectinase and cellulase from A. niger and Trichoderma longibrachiatum ), and Vinozym G (pectinlyase, polygalacturonase, hemicellulase, and cellulase from A. niger ). The treatment of Ribier grape skin with Vinozyme C for 2 h gave optimum extraction ( Munoz et al., 2004 ). A schematic diagram for the extraction of value-added products from the grape industry is shown in Fig. 6.2.
What is grape juice used for?
