Abstract: Effects of prestorage heat treatment on the texture of three apple cultivars: 'Gloster,' 'Golden Delicious' and 'Jonagold' (Malus domestica Borkh.) were studied before and after hear treatments at different time-temperature combinations. Changes of apple firmness, extractable juice content, background color, soluble solids concentration (SSC) and pH values were determined after 4 months cold storage (2C, 95% RH). Prestorage heat treatment can inhibit 'Golden Delicious' softening during cold storage but less effective for 'Jonagold' apples. Severe internal browning was found for heat treated 'Gloster' apples after cold storage. Heat treatments had no benefit on apple juiciness maintenance. Heat treated apples showed more physiological disorders compared with the nontreated apples after 4 months cold storage. The effect of prestorage heat treatment seems to be cultivar dependent.
