Actinidia arguta, post-harvest, storage, quality, punnet
Baby kiwi fruits (Actinidia arguta) represents a relativy new product in the fresh italian market and the crop is grown in recent years. They are similar to berries and their storage time is different from other kiwi. The aim of this work was to evaluate the evolution of some quality parametres of packaged fruits of two cultivar actually marked under the Nergi® brand (Hortgem Tahi®and Hortgem Rua®). Among all the monitored parametres (weight losses, colour, total soluble solids content, titratable acidity, dry matter, firmness, textural parametres and total polyphenol content) during storage at low temperature (1±1°C), up to 60 days , is possible to adfirm as baby kiwi are very suscettible to pulp firmness decrease. Generally samples of cv Hortgem Tahi® andHortgem Rua® packed with the lid have maintained an higher pulp if compared with the control values. The stability of the peel colour and the limiting of the weight losses during all the storage time are successfully preserved in this preliminary study.
