| 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. |
