APPLE''S DEHYDRATION BY THE IRRADIATION PRETREATMENT |
| |
| Abstract: | Co γ ray irradiation was used as a pre treatment method to dry the apple. The aim of this study was to discover the effect factor concerning the change of the apple cell structure which would affect the speed of drhydration and the relation between the speed of hot air dehydration and the irradiation dose. The results demonstrated that with the increasing of irradiation dose. the damage of apple's vacuole membrane increased. The positive correlation was shown in slice thickness and dehydration rate, the relation of the irradiation dose and the temperature of hot air was negatively correlated. The optimum of pre treatment was gained for slice thickness, the irradiation dose and dry temperature of hot air. |
