摘　　要：为了更好、高效地应用植物源马铃薯发芽调控剂香芹酮,针对贮藏小环境研发出一种吨袋+内循环聚丙烯(PP)通风管+吸油棉载药的施药模式,并考察香芹酮结合该模式处理对马铃薯贮藏效果和油炸薯片色泽的影响。在贮藏温度10℃的条件下,应用香芹酮对薯芽开始萌动的马铃薯进行处理,同时以不进行抑芽处理的4℃网袋贮藏(CK-4)和10℃吨袋贮藏(CK-10)的马铃薯为对照,处理后每6周测定马铃薯的芽长、发芽率和失重率,并在贮藏末期对马铃薯腐烂率、贮藏品质和油炸薯片色泽进行评价。结果表明,贮藏9个月,CK-4和CK-10发芽率均为100%,而香芹酮处理马铃薯未发芽,失重率和腐烂率分别较CK-10降低14.90、23.01个百分点,还原糖含量较CK-4降低59.86%,且得到的油炸薯片色泽最好。综上,香芹酮结合吨袋内循环施药模式处理能显著抑制马铃薯发芽,降低腐烂率和失重率,保持贮藏品质;相比低温贮藏,在抑制马铃薯发芽的同时,能够将还原糖含量保持在较低水平,避免了马铃薯的“低温糖化”现象,在实际生产中对马铃薯具有较好的贮藏效果与应用潜力。In order to make better and more effective use of potato germination regulator carvone derived from plant,an application mode combining ton bag with internal circulating ventilation polypropylene(PP)pipes and oil-absorbing cotton for drug carrying was developed for small storage environment,and the influence of carvone combined with this application mode on potato storage effect and color of fried potato chips was investigated.When the potato sprout began to peep,potatoes were treated with carvone at 10℃.Meanwhile,potatoes with no sprout inhibition treatment stored in mesh bag at 4℃(CK-4)and in ton bag at 10℃(CK-10)were used as control groups.The sprout length,sprouting rate and weight loss rate of potatoes were determined at 6-week intervals.Besides,the decay rate and storage qualities of potatoes,the color of fried potato chips were assessed at the end of storage.The results showed that the carvone treated potatoes did not sprout after 9 months of storage,while the sprouting rate of the control potatoes was 100%.Besides,the weight loss rate and decay rate of the carvone treated potatoes were reduced by 14.90 and 23.01 percentage points compared with CK-10 treatment,respectively.The reducing sugar content was reduced by 59.86%compared with CK-4 treatment.Meanwhile,the best color of fried potato chips was acquired.In summary,the carvone treatment combined with this application mode can significantly inhibit potato sprouting,reduce decay rate and weight loss rate,and maintain storage quality.Especially compared with the low temperature storage,it could keep the reducing sugar content at a lower level when inhibiting potato sprouting,avoiding the phenomenon of“low temperature saccharification”,which indicates that carvone treatment combined with the application mode has good storage effect on potatoes and application potential in practical production.
