摘　　要：将气调保鲜技术应用于甘薯的贮藏,研究不同的气调贮藏条件对甘薯保鲜效果的影响,筛选最佳气调贮藏条件,并将保鲜效果同普通冷藏对照组比较。结果表明:采用温度12℃,CO25.0%,O28.0%,相对湿度90%的气调贮藏条件,保鲜效果比普通冷藏对照组明显更好。气调贮藏150 d,感官新鲜饱满,不生根萌芽、不软腐、不糠心,好薯率提高15.8个百分点,失重率减少4.9个百分点,VC和β-胡萝卜素保存率分别提高24.8和21.8个百分点,呼吸曲线明显下移,刚入贮时提早5 d进入呼吸平稳期,所有呼吸强度值减少40%以上。To choose the optimum condition about controlled atmosphere storage of sweet potato, the influence of different condition to the result of keeping fresh of sweet potato was studied, and the result of keeping fresh was compared with comparison. The results showed： the controlled atmosphere storage condition of 12 ℃, CO2 5.0 % , 02 8.0 % ,relative humidity 90 % was obviously better than the condition of ordinary refrigeration storage. After stored 150 days under the optimum condition, the sweet potato did not take root bud, not soft rot, not hollowness,and it＇s appearance was plump; the keeping rate of good sweet potato increased by 15.8 percentage points; the weight losing rate decreased by 4.9 percentage points, the Vc and 13-carotene content increased by 24.8 and 21.8 percentage points, the breathing curve came down obviously; the date that respiration rate become steady brought forward 5 days ; all of the respiration rate decreased more than 40 %.
