Agriculturetofeeda growingpopulation inthe country andalsoforpoliticaland socialreasons, sustainable developmenthas beenan importantmission.Agricultural waste is now one of the challenging debates on economic policy has becameand it tends to undermine food security, social ,cultural and economic prosperity in the world. In this regard, one of the main problems in the agricultural sector of Alborz Province is the waste ofagricultural products .The two main causes of waste for producing uncontrollable factors, including political, social , cultural and economic and the controllable factors, agricultural waste during harvest and post-harvest stages are classified.
Inthisstudy,the first phaseaimed toassess andidentify the factorsleadinghorticulturalproducts of Alborz Provincelesionsin various stagesof production, harvest, post-harvesttechnology, processingandfinal consumption using a group of people based on their role in the supply chain Perspective (manufacturer or distributor, or simply working in production as a consumer),questions were asked basic concepts as well as on multiple factors affecting lesion formation in various stages of production to consumption chain. In the second phase of the project with regard to the results of the evaluation questionnaire (Phase I) and the scientific results of the previous findings, it was shown three kinds of packaging ,related to the layers , transport and storage time or cold storage lesions are highly effective. Therefore we have evaluated the effects of the three factors on the shelf life and the physicochemical properties of tomato (Commercial Var. of Shiva)contain of changes of weight, color, texture, acidity, brix, pH and Ripening factor, in the twenty-day period of storage ( at 9°C and 85-90 % of RH).
The results of thisresearch indicate , the number of layers in packaging, transport and storage time has the significant effects on qualitative and quantitative characteristics of tomatoes .Because the upper layer has received the greatest amount of the impact energy and destructive effects during transport .
Finally, the overall assessment was made ??clear , we can produce the optimum samples with applying the suitable packaging, transportation and storage,that sustain the storage period of 10 days for the samples maintained at an optimum level.
Keywords: waste, transportation, packaging, garden products, tomato, Alborz Province.
