目的 研究不同电商包装对冬桃振动后的保护性能以及不同测试标准对果品的损害程度。方法 以“映霜红”冬桃为研究对象,分别采用瓦楞纸板隔衬+EPE网套（P1）、EPE拉伸隔衬（P2）和压泡纸（P3）3种缓冲包装形式,开展模拟运输试验,测定桃果的质量损失率、褐变程度、总可溶性固形物和可滴定酸含量,筛选出最优包装,并选用ISTA 6A和3L 2种测试标准,检验包装对桃果的保护性能。结果 压泡纸包装方式（P3）扫频传递率最低,质量损失率仅上升了1.4%,褐变值、TSS和TA的变化小于P1、P2包装,对冬桃果实的保护性更好。在6A标准测试下,该包装形式桃果的质量损失率最高为4.6%,BI值、TSS和TA的变化率稳定,各指标显著优于3L标准。结论 压泡纸包装对冬桃的保护性能更好,可通过ISTA 6A和ISTA 3L测试,且3L测试标准对包装的要求更为严格。
Abstract
The work aims to investigate the protective performance of different e-commerce packaging materials for winter peaches after vibration and evaluate the damage levels proposed by different testing standards. Winter peaches "Yingshuanghong" were taken as the research object and three cushioning packaging types including corrugated cardboard (P1), EPE stretch tray (P2), and bubble-compressed paper (P3) were adopted to carry out simulated transportation experiments and measure key quality parameters, including weight loss rate, browning index (BI), total soluble solids (TSS), and titratable acidity (TA). The optimal packaging was selected and the ISTA 6A and 3L standards were applied to validate the packaging performance. The bubble-compressed paper (P3) exhibited the lowest sweep frequency transmissibility, with the weight loss of winter peaches increasing by only 1.4% and the changes in BI value, TSS and TA less than those in P1 and P2, demonstrating superior protective effects compared to P1 and P2. Under 6A standard testing, the maximum weight loss of peaches in this packaging was 4.6%, while BI, TSS, and TA remained stable, significantly outperforming the 3L standard. In conclusion, the bubble-compressed paper (P3) provides the most effective protection for winter peaches, meeting both ISTA 6A and 3L standards. Notably, the ISTA 3L standard imposes stricter requirements on packaging performance.
