The HPLC sugars profiles show that sucrose is major sugar, followed by glucose and fructose in pineapple fruit (Table 1). Glucose and fructose levels in fruit of storage at 6 ◦C increased dramatically to maximum values on day 18 and followed by a decrease. Fruit held at 10 ◦C, in which glucose and fructose contents increased markedly and reached a peak on day 6 and then decreased during the latter period of storage. Changes in the contents of glucose and fructose in
