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 % ,O2 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 andβ-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%.
