Inorder to find the feasibility of sustainable production of vegetable products in central Thailand, the vegetable processing plants' background, the ways of doing and the target achieving for standards were surveyed by using questionaires. The laboratory analysis was also done for the study of the effect of the pretreatments on the pH and the nitrate content of some selected fresh vegetables and the quality of some selected canned vegetables. It is possible for the sustainable production of vegetable products in central Thailand due to most of the replied factories have abilities to develop and improve their process and quality control on their raw materials, process and finished products. They also are alert to achieve for the standards, i.e., HACCP, ISO, etc., although some big and medium scale factories already got one or more standards. The factories are willing to use the organic raw materials according to the consumers' demand, although the sufficiency, the cost and the hygienic conditions of the raw materials are still in doubt. The pretreatments of raw materials in the vegetable processing can reduce the nitrate content of the vegetables while the analysis results showed very low the nitrate and the lead content of the selected canned vegetable samples.
