Three sweet pepper varieties viz. Swarna, California wonder and Oroballe were treated with derivatives of salicylic acid viz. Acetyl salicylic acid (ASA), 5 Sulpho salicylic acid (5 SSA) and Gentisic acid (GA) at mM and 1 mM concentrations under ambient condition (20±5°C) and analyzed for their change in physical and biochemical profile at 3 days interval for 9 days. Fruits treated with 1 mM acetyl salicylic acid and gentisic acid significantly delayed the senescence process by delaying the changes of weight, and firmness. Application of salicylic derivatives also lead to retention of total soluble solids, total phenolics, antioxidants and inhibited enzyme activities such as PME at the end of storage. Thus the derivatives of salicylic acid may be effective in delaying the process of deterioration, maintenance of quality while extending the shelf life of sweet peppers when stored in ambient condition. | Application of salicylic acid derivatives to extend shelf life of sweet pepper (Capsicum annum L)
