Cold Storage Characteristics of Four Fresh Pineapple Cultivars (Ananas comosus (L.) Merr)

Abstract

　―Four varieties of fresh pineapple (Ananas comosus (L.) Merr)― "summer gold," "soft touch," "Bogor" and "N67-10"―, were stored for 15 days at 5°C and 15°C, and they were examined for total acidity, Brix, peel injury, signs of internal browning and weight loss. It was observed that during the storage time, the total acidity of all the varieties increased, whereas Brix remained stable. Peel injury proceeded in 2 varieties, namely "summer gold," which reached the sales limit by 5 days at 5°C and 15°C, and "soft touch," which reached the sales limit by 9 days at 15°C. Internal browning proceeded in the "summer gold" variety, and its sales limit was reached by 5days at 5°C and 15°C. "N67-10" was the only cultivar that maintained good condition throughout the study period (15days).
