Popis: SummaryAccurate measurement of colour and firmness of grape berries was done during storage under simulated shelf life conditions (18°C, 60% r.h.). Darkening of their yellow colour was expressed by the rapid increase in total colour difference ( ΔE) following the rise of weight loss. Hue and chroma (brightness) slightly decreased during the three days of shelf life. Changes in colour were closely related to the weight loss and within 40 h the limit of marketability (1.2%) was surpassed. Weight loss affected berry firmness more than colour and the use of cushioning paper dividers in the box controlled the percentage of damaged berries but diminished their firmness. Water stress was the main cause of this quality decline, therefore use of cushioning or other packing materials with high absorbing surface has to be considered carefully.
