Texture analysis as a method for grape berry characterization

The marketability of table grapes is mainly characterized by berry size, color, taste and texture. Mechanical measurements grape berries could provide objective information on the textural qualities berries. In addition, this method might be suitable to study effects phytotechnical methods (such as girdling) quality. aim preliminary work was demonstrate how instrumental testing used examine girdling texture define characteristics Cane carried out at veraison in two varieties. Texture analysis performed several times during maturity. Besides examination another five varieties were analyzed assess their mechanical properties. Double compression test determine hardness its derived parameters. Puncture applied evaluate skin hardness, elasticity break energy. Skin thickness also investigated. Berry girdled grapevines significantly affected technique. Most parameters showed differences among seven cultivars.
