Abstract

The invention discloses application of polyhexamethylene guanidine in citrus sour rot prevention and treatment, and a citrus antistaling agent containing polyhexamethylene guanidine. The citrus antistaling agent containing polyhexamethylene guanidine comprises: by mass, 0.05 to 0.6% of polyhexamethylene guanidine, 0.05 to 0.2% one or more of imidazole bactericides and benzimidazole bactericides, 0.02 to 0.15% of a polyoxyethylene ether or a quaternary ammonium salt emulsifier, and the balance water. The citrus antistaling agent containing polyhexamethylene guanidine can obviously inhibit decomposition of citrus fruits such as sugar orange fruits and the like in storage, and especially, can inhibit sour rot. If sugar orange fruits treated by the citrus antistaling agent containing polyhexamethylene guanidine is stored at a normal temperature of 15 to 25 DEG C for 40 days, a sour rot incidence of the sugar orange fruits is below 15.4%, wherein a sour rot incidence of a control group is 76%. Therefore, the citrus antistaling agent containing polyhexamethylene guanidine obviously reduces a sour rot incidence of Citrus reticulate Blanco, and greatly improves citrus economic values.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to the application of polyhexamethylene biguanide hydrochloride in the prevention and treatment of citrus acid rot and its preservation agent. Background technique [0002] Citrus is one of the bulk fruits in the world, and my country is the largest producer of citrus in the world. According to statistics, in 2008 my country's citrus cultivation area reached 30.45 million mu, with a total output of 23.31 million tons, accounting for about 23% of the world's citrus production. The main problem of post-harvest citrus is severe rot. The main diseases of citrus during post-harvest storage and distribution include acid rot, green mold, black rot and pedicle rot. At present, the most effective way to control postharvest diseases of citrus fruits is low-temperature storage combined with chemical fungicide treatment. However, the control of rot, especially acid rot, is still ...
