Abstract:

Objective】This study aims to enhance the storage and transportation quality of Xinjiang dried apricots, thus ensuring food safety during processing and minimizing losses from insect pests and economic losses in the industry by applying hypobaric treatment combined with SO2 fumigation to manage insect pests in order to reduce SO2 residues and mitigate storage losses of dried apricots.【Methods】The efficacy of hypobaric treatment combined with SO2 fumigation was evaluated using different SO2 concentrations (250, 500, 1000 μL/L) and six C×T values (0, 2,000, 4,000, 6,000, 8,000, 10,000 μL/(L·h)). The control effects on eggs, larvae, pupae, and adults of Plodia interpunctella in dried apricots were evaluated, along with changes in dried apricots quality.【Results】When the C×T value reached to 10,000 μL/(L·h), the mortality rate of Plodia interpunctella in different life stages reached 100%. Analysis of LT50 and LT95 values revealed the sensitivity order to hypobaric treatment combined with SO2 fumigation: adult > egg > pupa > larva. This method effectively reduced SO2 residues, improved food safety, and maintained sensory quality of dried apricots.【Conclusion】Hypobaric treatment combined with SO2 fumigation shows promise in preventing and controlling Plodia interpunctella infestations and reducing SO2 residues in dried apricots.

摘要:

目的】保持新疆杏干贮运品质和提高加工过程中的食品安全性,减少杏干虫害发生及产业经济损失。【方法】采用减压二氧化硫(Sulfur dioxide, SO2)熏蒸方式,筛选不同SO2浓度(250、500和1 000 μL/L)熏蒸效率,评价6种C×T值(0、2 000、4 000、6 000、8 000和10 000 μL/(L·h))对杏干中印度谷螟虫卵、幼虫、蛹和成虫的控制效果及果实品质变化。通过控制虫害的发生,以减少SO2残留,降低杏干产后损失。【结果】当C×T值达到10 000 μL/(L·h)时,不同生命阶段的印度谷螟死亡率均达到100%。印度谷螟对减压SO2熏蒸致死敏感性为成虫>卵>蛹>幼虫。减压SO2熏蒸不仅可以降低SO2残留,提高市场销售和加工过程中的食品安全性,还可以显著保持杏干的感官品质。【结论】减压SO2熏蒸在防控由印度谷螟导致的虫害发生,减少果实中SO2残留方面具有很好的应用前景。
