晚熟葡萄脉冲渗透式双重杀菌贮藏保鲜综合技术研究

Late-maturing Grape Fresh-keeping Comprehensive Technology Research by Pulse and Penetration Double Sterilization

以陕西关中地区产晚熟"红地球"葡萄为试材,进行连续3年集成全程温控精准管理、气调保鲜、化学保鲜剂技术试验。结果表明,每箱装5 kg葡萄,经脉冲式杀菌+渗透式葡萄专用保鲜剂(7+2)处理,贮藏期间冷库温度控制在-0.5^-1.5℃时,可使晚熟红地球葡萄贮藏保鲜时间由原来的45~60 d延长到140~175 d,而葡萄综合品质不发生显著改变。因此,入库前脉冲式杀菌,入库后经渗透式葡萄专用保鲜剂杀菌,保鲜剂搭配方式及使用剂量为(7+2)组合时,为陕西关中地区产红地球葡萄贮藏保鲜的最佳组合。

Taking late-maturing ＂Red Globe＂ grape of Shanxi Guanzhong area as the material, through three years the experiment was conducted during which the whole process using integrated management of temperature control precision, modified atmosphere, chemi- cal preservatives technology. The results showed that for each box containing 5 kg of grapes, after pulse type sterilization ＋ osmosis type grape fresh-keeping agent （7＋2） treatment, and controlling cold storage temperature at 0.5-1.5 ℃, the fresh-keeping technology could make the late - maturing grape fresh-keeping time extended from 45-60 days to the present 140-175 days, and grapes quality did not changed significantly during the period of storage. Therefore, for ＂Red Globe＂ grape fresh-keeping in the Guanzhong region of Shaanxi the best combination technology includes by the pulse type sterilization before entering storage, and by the osmosis grape fresh-keeping agent sterilization after entering storage, and the fresh-keeping agent combination method and the dose for （7 ＋ 2）.
