The use of a sprout suppressor is crucial for the use of potatoes beyond their natural dormancy period. The main sprout inhibitor used on a commercial scale, chlorpropham (CIPC), is becoming increasingly limited owing to its toxicity. Therefore, we evaluated the effectiveness of 1,4-dimethylnaphthalene (1,4-DMN) compared to CIPC in controlling sprouting and maintaining the quality of potato, Solanum tuberosum 'Asterix', during cold storage. Treatment with 1,4-DMN reduced fresh weight loss and controlled the number and length of sprouts comparable to CIPC. Compared to the control, both sprouting inhibitors led to higher starch and lower reducing sugar contents, and the tubers retained the recommended quality for industrial processing. After frying, less browning was observed in French fries obtained from 1,4-DMN- or CIPC-treated tubers. We ascertain that 1,4-DMN besides being an efficient sprouting inhibitor and alternative to CIPC, it contributes to maintaining the quality of French fries after cold storage.
使用抑芽剂对于延长马铃薯自然休眠期后的使用至关重要。由于氯苯胺灵（CIPC）的毒性，它作为主要的商业抑芽剂正变得越来越有限。因此，我们评估了 1,4-二甲基萘（1,4-DMN）在控制发芽和保持马铃薯（Solanum tuberosum 'Asterix'）冷藏期间品质方面的效果，与 CIPC 相比。用 1,4-DMN 处理可减少新鲜失重并控制发芽的数量和长度，与 CIPC 相当。与对照相比，两种抑芽剂都导致淀粉含量升高和还原糖含量降低，且块茎保留了适合工业加工的质量。薯条油炸后，用 1,4-DMN 或 CIPC 处理的块茎获得的薯条褐变程度较低。我们确定，1,4-DMN 除了是一种有效的抑芽剂和 CIPC 的替代品外，它还有助于保持冷藏后薯条的品质。
