| 为探究预充气微孔气调包装盒对无花果贮藏品质的影响，以未穿孔包装为对照（CK），分别采 用CM10（10个微孔，孔径50~58 μm）和CM20（20个微孔，孔径40~50 μm）两种微孔气调保鲜盒并预充 10% O2+6% CO2+84% N2的气体组分对无花果进行包装处理，于（0±0.5）°C下贮藏28 d，定期测定无花 果的贮藏品质及相关酶活性。结果表明，与CK组相比，微孔气调处理可较好地维持包装内预充气体 浓度，使其保持动态平衡状态；CM20处理组能够有效抑制无花果的呼吸强度，更好地保持果实感官品 质、色泽和硬度，减缓可溶性固形物（TSS）、可滴定酸（TA）、VC、总酚和类黄酮含量的损失并抑制无花 果果实中过氧化氢（H2O2 ）和丙二醛（MDA）的积累。其中，CM20处理组将无花果呼吸高峰推迟到第21 天，呼吸高峰较CK组降低34.35%；在贮藏28 d时，CM20处理组的感官评分比CK组高7.56分，仍具有 商业价值，VC含量、类黄酮含量、过氧化氢酶（CAT）活性、过氧化物酶（POD）活性和超氧化物歧化酶 （SOD）活性分别比CK组高72.33%、18.70%、50.00%、59.10%和72.85%，且H2O2和MDA含量较CK组低 15.75%和61.63%。因此，预充气微孔气调保鲜盒能够显著降低无花果的呼吸强度，延缓硬度的下降 和营养物质的流失，维持较高的抗氧化活性，从而延长货架期；其中CM20处理组在维持无花果采后贮 藏品质方面最为显著。 |

| To investigate the effect of pre-gas-flushed laser-microperforated modified atmosphere packaging boxes on the storage quality of figs, two types of microporous modified atmosphere preservation boxes, CM10 (10 micropores, diameter 50-58 μm) and CM20 (20 micropores, diameter 40-50 μm), were used and pre-filled with 10% O2+6% CO2+ 84% N2 gas components to package figs. Non-perforated packaging served as the control (CK). All samples were stored at (0±0.5) ℃ for 28 days, and their storage quality and related enzyme activity were regularly measured. The results showed that, compared with the CK group, the microporous modified atmosphere treatment group better maintained the initial gas concentration inside the package in a dynamic equilibrium. The CM20 treatment group could effectively inhibit the respiratory intensity of figs, better maintain the sensory quality, color, and hardness of the fruit, slow down the loss of soluble solids (TSS), titratable acids (TA), vitamin C (VC), total phenols, and flavonoids, and inhibit the accumulation of hydrogen peroxide (H2O2) and malondialdehyde (MDA) in figs. Specifically, the CM20 treatment group delayed the peak respiration of figs to the 21st day, with peak respiration 34.35% lower than that of the CK group. After 28 days of storage, the sensory score of the CM20 treatment group was 7.56 points higher than that of the CK group, still indicating commercial value. At this time, the VC content, flavonoid content, catalase (CAT) activity, per? oxidase (POD) activity, and superoxide dismutase (SOD) activity in the CM20 group were 72.33%, 18.70%, 50.00%, 59.10%, and 72.85% higher, respectively, than those in the CK group, while the H?O? and MDA contents were 15.75% and 61.63% lower. Therefore, pre-inflated microporous modified atmosphere preservation boxes could significantly reduce the respiratory intensity of figs, delay the decrease in fig hardness and nutrient loss, maintain high antioxidant properties of figs, and extend the shelf-life of figs. The CM20 treatment group showed the most significant effect in maintaining the post-harvest storage quality of figs. |
