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.
