产业升级视域下冷链物流对农产品质量的影响研究

Impact of Cold Chain Logistics on Quality of Agricultural Products from Perspective of Industrial Upgrade

目的为了优化农产品冷链物流安全性能,针对产业升级视域下冷链物流对农产品质量的影响进行研究。方法以葡萄为测试对象,分别利用不同保鲜剂、CK空白对照组的处理方式检验冷链物流低温贮藏对农产品质量影响。测定SO_(2)积累量、SO_(2)残留、腐烂率、漂白率、落粒率进行测定,并对实验所得数据进行统计处理。结果天数增加下,各个处理袋中SO_(2)积累量都呈上升趋势,CT2与免扎眼结合、CT2与CT5结合下的处理在观察期间释放SO_(2)的形式更为理想;CT2加免扎眼处理、精准打孔加免扎眼加吸水垫处理、CT2加CT5在SO_(2)残留处理中较为理想。结论经综合对比,腐烂、漂白和落粒具有良好抑制效果的是CT2、CT2加CT5以及CT2加免扎眼。对如何提高农产品冷链物流质量分别从法律法规、农产品冷链物流平台、冷链物流体系基础设施建设等方面提出了对策。

Objective To optimize the safety performance of cold chain logistics of agricultural products,the impact of cold chain logistics on the quality of agricultural products was studied from the perspective of industrial upgrading.Methods With grapes as the test object,the effects of cold chain logistics and low temperature storage on the quality of agricultural products were tested by using different preservative and CK blank control groups.SO_(2) accumulation,SO_(2) residue,decay rate,bleaching rate and dropping rate were determined,and the experimental data were statistically processed.Results As the number of days increased,the accumulation of SO_(2) in each treatment bag showed an upward trend.The combination of CT2 and no-tight eyes,and the combination of CT2 and CT5,were more ideal for the release of SO_(2) during observation;CT2 plus no-tight eyes,accurate punching plus eye-free padding plus water-absorbing pad treatment and CT2 plus CT5 were ideal for SO_(2) residual treatment.Conclusion After comprehensive comparison,CT2,CT2 plus CT5 and CT2 plus eye-free avoiding rot,bleaching,and falling particles have a good effect.The proposed countermeasures include how to improve the quality of agricultural cold chain logistics from the aspects of laws and regulations,agricultural cold chain logistics platform and infrastructure construction of cold chain logistics system.
