| 目的 研究不同包装材料对马铃薯品质的影响，依据马铃薯品质指标变化，选取较优的包装与贮藏工艺，以延长其贮藏期。方法 分别用聚乙烯（PE）、聚丁二酸丁二醇酯（PBS）及含有壳聚糖（CTS）、纳米氧化锌（Nano-ZnO）和山梨酸钾（Pto）的抗菌薄膜作为包装材料，以常规贮藏作为对照，贮存期为120 d，每隔30 d检测马铃薯块茎品质指标的变化情况，分别考察包装材料对马铃薯的呼吸强度、维生素C含量、葡萄糖含量、褐变度、丙二醛含量、干物质含量、发霉等指标的影响。结果 所设计的抗菌薄膜对马铃薯包装处理后，可有效降低其贮藏过程中的发芽率、腐烂率以及营养物质的流失速度，有利于维持马铃薯的营养品质及感官品质。其中，抗菌薄膜PE/CTS/Pto作为马铃薯的包装材料时，可减弱马铃薯的呼吸作用，还原糖质量分数维持在0.63%，丙二醛含量为0.18 μmol/g。结论 用抗菌薄膜PE/CTS/Pto作为马铃薯的包装材料，可有效延长马铃薯的贮藏期。 |

| The work aims to study the effect of different packaging materials on the quality of potato and select better packaging and storage process according to the change in the potato quality indicators, so as to extend the storage period. With polyethylene (PE), polybutylene succinate (PBS) and antibacterial film containing chitosan (CTS), nano-zinc oxide (Nano-ZnO) and potassium sorbate (Pto) as the packaging materials, taking the conventional storage as a control, the effects of packaging materials on the respiration intensity, malondialdehyde content, dry matter content, mouldiness and other indicators of the potato were respectively investigated during the 120-day storage period. The change in potato tuber quality indicators was detected every 30 days. The results showed that, after the potato package was treated by the antibacterial film designed, the germination rate and rotting rate of the potato during the storage and the nutrient loss speed could be effectively reduced. It was beneficial to maintain the nutritional quality and sensory quality of the potato. Among them, the antibacterial film PE/CTS/Pto used as the packaging material of potato could slow down the respiration of potatoes, and restore and maintain the sugar mass fraction at 0.63% and malondialdehyde content at 0.18 μmol/g. In conclusion, the antibacterial film PE/CTS/Pto used as the packaging materials of potatoes can effectively extend the potato storage period. |
