The high potential of essential oils (EOs) in vapor phase to reduce ethylene biosynthesis was studied at (1) in vitro experiment (nonencapsulated) with citral vapor applied to broccoli florets (sensitive product model) and apple wedges (high-ethylene producer model), and (2) validation experiment with EOs vapor released from active paper sheets (encapsulation) in broccoli florets. Ethylene production (22 °C) of broccoli and apples was reduced by 30–40% with low doses (2.5–3 μL L^–1) of citral. Such ethylene inhibition was validated using industrial EOs active paper sheets for packaging of broccoli florets at different temperature scenarios (2, 7, 15, and 22 °C). The broccoli ethylene production was reduced with vapor EOs by 30–40% (22 °C) and up to 40–70% (2 °C). Conclusively, EOs-active paper sheets highly controlled ethylene production in broccoli florets either at optimum storage temperature (2 °C) or under abusive commercialization temperatures (22 °C).

活性包装中的精油在高度减少西兰花和苹果中乙烯生物合成方面的潜力

在 (1)体外实验（非封装）中研究了蒸气相精油 (EOs) 降低乙烯生物合成的高潜力，柠檬醛蒸气应用于西兰花小花（敏感产品模型）和苹果楔（高乙烯生产模型） ，和 (2) 使用从西兰花小花中的活性纸张（封装）释放的 EO 蒸气的验证实验。西兰花和苹果的乙烯产量 (22 °C) 在低剂量 (2.5–3 μL L ^–1) 的柠檬醛。使用工业 EO 活性纸在不同温度场景（2、7、15 和 22 °C）下包装西兰花小花时，这种乙烯抑制得到了验证。使用蒸汽 EO 使西兰花乙烯产量降低 30–40% (22 °C) 和高达 40–70% (2 °C)。总之，在最佳储存温度 (2 °C) 或滥用商业化温度 (22 °C) 下，EOs 活性纸片高度控制了西兰花小花中的乙烯产量。
