The Influence of ^(60)Co-Irradiation on the Dehydration Characteristics and Quality for Slice Apple

进行了不同辐照剂量、热风温度、切片厚度对苹果脱水速率及品质的影响试验,结果表明:该三因子影响苹果片的脱水速率和外观质量。辐照剂量增加,热风温度增高,脱水速率高,VC含量和复水比下降。辐照剂量、热风温度、切片厚度三因素对脱水速率和干制品的外观质量、VC含量、复水比等四指标大都呈显著影响。

Experiments were undertaken made to study the influence of different dosage of irradiation, temperature of hot air, thickness of the slice apple on the rate of dehydration rate of irradiated apple. A conclusion was reached that the three-factors affect the rate of dehydration and appearance quality of slice apple. The higher the dosage, the greater the rate of dehydration of apple, the higher the temperature, the less VC content of dried apple, and the lower the rehy-dration rate. The three factors of irradiation dosage, hot-air temperature, and initial slice thickness significantly affected the four indexes of appearance quality, VC content, dehydration rate and rehydration rate.
