摘要：采用正交试验确定对灵武长枣的发病腐烂有抑制作用的中药抑菌剂最佳浓度,并使用CaCl2、GA3与抑菌剂配制4种保鲜剂对长枣进行处理,在常温(18～22℃)条件下贮藏30d,对各处理样品和对照的失重率、腐烂率、软化率及品质指标进行分析。结果表明,保鲜剂中各成分的适宜浓度分别为40g/L的连翘乙醇提取液、20g/L的高良姜水提取液、12g/L的丁香乙醇提取液、10g/kg的CaCl2及75mg/kg的GA3,灵武长枣用此保鲜剂进行处理,常温条件下贮藏30d,腐烂率仅有12.64%,和对照相比有极显著差异(p<0.01),软化率也只有1.83%,失重率为1.82%,同时也保持了果实较好的内在品质,VC含量达259.36mg/100g,与对照差异为极显著,可溶性固形物为25.4%、酸度为0.4%、硬度为12.37kg/cm2,使长枣经常温贮藏后仍具有较好的脆度和风味。
By orthogonal test, the concentration ofbacteriostatic agent （traditional Chinese medicine preservative） against decay of Lingwu Chang date caused by pathogenic fungi was optimized. Four preservers were made from bacteriostatic agent, CaCh and GA3. Lingwu Chang dates were treated with different preservatives and stored for 30 d at room temperature （18 to 22 ~C）, and then the rate of decay, rate of softening, loss rate of water and the index of quality were analyzed respectively. The results showed that the optimal concentrations of preservatives are 40 g/L ethanol extract of Forsytia suspense （Thumb.） Vahl, 20 g/L water extract ofAlpinia officinarum Hanc, 12 g/L ethanol extract ofEugenia caryophyllata Cl＇humb）, 10 g/L CaC12 and 75 mg/kg GA3 respectively. After 30 d storage, the rate of decay is only 12.64 %, the rate of softening is 1.83%, and the loss of water is 1.82%. Meanwhile, the quality of fruit is well maintained. The content of VC is 259.36 mg/100 g, the content of soluble solids is 25.4%, the titratable acidity is 0.4%, and the firmness is 12.37 kg/cm2. The fruit still has high firmness and fine flavor after storage.
