Texture Changes in Apple Cultivars During Storage in Different Conditions

In Poland, apples are stored in cold storage plants, with either normal or controlled atmosphere. Estimation of physical parameters permits the determination of the current state of the fruit and the prediction of allowable periods of commercial turnover after storage. The objective of the study was to characterise, on the basis of experimental studies, the firmness of the flesh and the skin strength in the puncture test of apple cultivars Ligol, Gloster, Golden Delicious, and Jonagored held in cold storage under different conditions. Apple storage conditions have a decisive effect on the preservation of the texture. In the course of cold storage of apples there takes place an unfavourable change in the analysed parameters of their texture The dynamics of changes in the analysed values characterising the texture was related to the varietal traits of the fruits.
