为进一步检验前期西兰花硅窗气调关键参数筛选研究结果，并期望得到相较于单一硅窗气调贮藏效果更好的保鲜剂结合硅窗气调包装的西兰花的贮藏方法。以甘肃特色高原蔬菜耐寒优秀西兰花为材料，采用60 mg/L的二氧化氯保鲜剂溶液、蒸馏水浸泡清洗处理，以无处理为对照，再结合2 ℃下硅窗面积分别为6、8 cm2的硅窗保鲜袋包装，通过叶绿素、抗坏血酸(Vc)、总酚、总花色苷和硫代葡萄糖苷含量等营养指标的测定，考察各处理方法对西兰花25 d贮藏期内品质的影响。结果表明，相较于单一的硅窗气调袋包装保鲜，保鲜剂或蒸馏水清洗处理结合硅窗气调保鲜有更好的保鲜效果，其中60 mg/L的二氧化氯保鲜剂溶液清洗处理效果更优。2 ℃贮藏温度下，同样处理方式的西兰花，硅窗面积为8 cm2的硅窗袋气调袋包装的保鲜效果要优于硅窗面积为6 cm2的硅窗气调袋包装；60 mg/L的二氧化氯保鲜剂溶液浸泡清洗，结合硅窗面积8 cm2的硅窗气调袋包装的西兰花的贮藏品质最好，在25 d贮藏期内各营养指标总体高于其他处理。

To further verify the results of the screening research on key parameters of silicon window modified atmosphere for broccoli in the early stage, and to expect to obtain a better storage method on which preservation agent combined with silicon window modified atmosphere for broccoli, this study used 60 mg/L chlorine dioxide solution and distilled water soaking and cleaning, compared to no treatment, then combined with silicon window modified atmosphere packaging bags with a silicon window area of 6 and 8 cm2 at 2 ℃ to store broccoli. Through the determination of nutritional indicators such as chlorophyll, ascorbic acid(Vc), total phenols, total anthocyanins, and thioglucoside content, this study investigated the effects of various treatments on the quality of broccoli during 25 day storage period. The results showed that compared to a single silicon window modified atmosphere packaging, the combination of fresh-keeping agent or distilled water cleaning treatment with silicon window modified atmosphere had a better fresh-keeping effect. The combination of 60 mg/L chlorine dioxide solution treatment with silicon window modified atmosphere was the best. At a storage temperature of 2 ℃, under the same treatment method, the preservation effect of broccoli packaged in a silicon window bag with a silicon window area of 8 cm2 was better than that of a silicon window bag with a silicon window area of 6 cm2. The storage quality of broccoli packaged with chlorine dioxide preservative combined with a silicon window bag with a silicon window area of 8 cm2 was the best, and all nutritional indicators are generally higher than other treatment groups during the 25-day storage period.
