Study on postharvest physiological changes and storage techniques of sugarcane.

Changes in contents of flavour materials, activities of neutral and acid sucrose invertases, and polyphenol oxidase (PPO) [catechol oxidase] activity in sugarcane (Saccharum officinarum cv. Badila) during storage were determined. The effects of packaging methods and preservative on the storage of peeled sugarcane were also evaluated. During storage, activities of sucrose invertases and PPO increased gradually, titratable acid, alcohol and reducing sugar contents increased, while sucrose and soluble sugar contents decreased. Vacuum packaging with preservative treatment could effectively inhibit the activities of sucrose invertases and PPO, and significantly reduce sucrose degradation and acid accumulation. Peeling and cutting stimulated the increase of respiration rate of sugarcane by 8.43 times. The shorter the sugarcane section, the more the respiration rate increased. Peeled sugarcane, combined with the application of preservative and vacuum packaging, could be stored for 20 days at 0 deg C.
