气调包装（MAP）[双向聚丙烯（BOPP-1或BOPP-2）]与抗菌剂枯草芽孢杆菌结合使用的效果，10（7）菌落形成单位（cfu）ml（-1）；乙二胺四乙酸二钠钙盐水合物（EDTA）（0.1%）；或 4-己基间苯二酚 (4-HR) (0.15%) 对荔枝采后腐烂控制和质量保持的影响麦克莱恩红被评估为商业二氧化硫熏蒸的可能替代品。果实分别浸入枯草芽孢杆菌、EDTA或4-HR（5分钟），吹干（25℃，3分钟），包装在BOPP-1中，在2℃，95%RH下保存18天，在14℃，75%RH下保存2天，腐烂程度明显减少。拮抗剂-BOPP-1组合还促进了储存期间细菌的最佳存活。观察到枯草芽孢杆菌在 BOPP-1（16% O-2、6% CO2；与 90% RH 相似）中有效存活，但在 BOPP-2（5% O-2、8% CO2；与 93% RH 相似）中其存活受到不利影响。链格孢 (Alternaria alternata) 和枝孢霉 (Cladosporium spp.) BOPP-1 处理中，念珠菌属、隐球菌属和接合酵母属是主要的腐烂真菌，而 BOPP-2 处理中，念珠菌属、隐球菌属和接合酵母属是主要的酵母菌。 BOPP-1 中的 EDTA、4-HR 或枯草芽孢杆菌联合处理可抑制多酚氧化酶 (PPO)，并显着减少果皮褐变和严重程度。尽管 BOPP 中的 EDTA、4-HR 或枯草芽孢杆菌联合处理在控制腐烂和褐变方面同样有效，但 EDTA 和 4-HR 通过显示更高的 h 值（橙粉色）影响了果皮的天然粉红色。在组合处理中，枯草芽孢杆菌+BOPP-1在20天的销售链中控制腐烂、保留颜色和整体荔枝果实品质的潜力最大。 (c) 2008 Elsevier Ltd. 保留所有权利。
The effects of modified atmosphere packaging (MAP) [bioriented polypropylene (BOPP-1 or BOPP-2)] in combination with antimicrobial agents Bacillus subtilis, 10(7) colony-forming units (cfu)ml(-1); ethylenediamine tetraacetic acid, calcium disodium salt hydrate (EDTA) (0.1%); or 4-hexylresorcinol (4-HR) (0.15%) on postharvest decay control and quality retention of litchi cv. McLean's Red were assessed as possible replacements for commercial SO2 fumigation. Fruits dipped in B. subtilis, EDTA or 4-HR (5 min) separately, blow dried (25 degrees C, 3 min), packed in BOPP-1, held for 18 d at 2 degrees C, 95% RH, and 2 d at 14 degrees C, 75% RH were significantly less decayed. The antagonist-BOPP-1 combination also promoted the best bacterial survival during storage. B. subtilis was observed to survive effectively in BOPP-1 (16% O-2, 6% CO2; similar to 90% RH), but its survival was adversely affected in BOPP-2 (5% O-2, 8% CO2; similar to 93% RH). Alternaria alternata and Cladosporium spp. were the major decay-causing fungi in BOPP-1 treatments, and Candida, Cryptococcus and Zygosaccharomyces were the predominant yeasts in BOPP-2 treatments. Combination treatments EDTA, 4-HR or B. subtilis in BOPP-1 inhibited polyphenol oxidase (PPO) and significantly reduced pericarp browning and severity. Although the combination treatments EDTA, 4-HR or B. subtilis in BOPP were equally effective in controlling decay and browning, the EDTA and 4-HR affected the natural pinkish-red colour of the pericarp by showing higher h degrees values (orange-pink). Among the combination treatments, B. subtilis+BOPP-1 had the best potential to control decay, retain the colour and the overall litchi fruit quality during a marketing chain of 20 d.
