Effects of combinational use of controlled atmosphere, cold storage and edible coating applications on shelf life and quality attributes of green peppers

The effects of combinational use of controlled atmosphere (CA), Semperfresh edible coating (sucrose polyester base coating) and cold storage on shelf life, quality attributes and post storage life of green slender peppers (Capsicum annuum L.) were investigated. Changes in weight, quality, pH, total titratable acidity, ascorbic acid, soluble solids, respiration rate and total chlorophyll content were recorded periodically for comparing the effects of the applied conditions. In the study, application of CA storage was determined to give the best results in terms of the analyzed parameters. Use of Semperfresh in combination with cold storage was significantly effective in retaining higher contents of vitamin C, and total chlorophyll. However, it didn't provide a synergetic benefit for improving the quality of the peppers under CA and normal air conditions.
