中文摘要:
      研究了壳聚糖双胍盐酸盐(CGH)对柑橘绿霉菌和柑橘青霉菌的抑菌能力,并通过涂膜的方法处理砂糖橘,测定了贮藏过程中果实失重率、可溶性固形物含量(TSS)、维生素C(Vc)含量及总酸含量(TA)的变化。结果表明,与壳聚糖(CTS)比较,CGH 对柑橘绿霉菌和柑橘青霉菌具有较强的抑菌能力,当CGH浓度为0.4 mg/mL和5.0mg/mL时,可分别完全抑制柑橘青霉菌和柑橘绿霉菌的生长;质量浓度为2%的CGH涂膜处理的砂糖橘在28(±2)℃下存放27d后,失重率仅为2.25%,TSS为13.7%,Vc含量为每100g砂糖橘鲜重含有15.01mg、可滴定酸含量为0.85%。与对照相比,CGH涂膜较好地保持了果实的品质。
英文摘要:
      The antimicrobial activities of chitosan biguandine hydrochloride (CGH) were investigated against Citrusgreen mold and Citrus Penicillium, respectively. Relation between variation and storage time of Citrus reticulata mass-loss ratio, total soluble solid, Vc content and soluble acid content was examined attentively after fresh-keeping process with CGH as coating film. CGH could completely inhibit the growth of Citrus Penicillium and Citrus green mold at 0.4 mg/mL and 5.0 mg/mL, respectively. CGH with concentration of 2% coating on Citrus reticulata showed a better preservation effect after 27 d storage under 28 依2益. The mass -loss, total soluble solid, Vc content and soluble acid content of Citrus Reticulata were 2.25%, 13.7%, 15.01 mg/100g, and 0.85%, respectively.
