Preservation of the quality of Actinidia kolomikta berries using a modified atmosphere

Abstract Actinidia berries are a unique natural source of ascorbic acid and many other important physiologically valuable nutrients, but they have short shelf life. A modified atmosphere is particular importance for preserving the quality during storage. The research was implemented in laboratory progressive technologies storing fruits vegetables center Federal State Budgetary Educational Institution Higher Education Michurinsky Agrarian University on Soroka variety. 600-700 g freshly picked were placed perforated plastic containers. storage technology provided cooling to temperature + 0.5 ° C, installation containers with Xtend package, packaging. packages had two mini-cranes each, designed connect gas-analyzer inlet pneumatic line return medium. Storage carried out refrigerator at constant C relative humidity 90%. During period, concentration oxygen, carbon dioxide, ethylene bag regularly measured, examined, their appearance assessed. It found that after three days storage, level gas concentrations inside package stabilized over next 28 range 3.1-3.5% dioxide 17.8-18.8% oxygen. intensity release increased sharply 28th day which led significant decrease commercial berries. studies shown preserve extend period berries, it possible recommend using atmosphere, ensures preservation original fresh optimal 24 days, yield standard 94.4%, 2.3 times higher than control. duration from 3 days.
