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