Hypobaric storage preserves fruit by combining cold storage with a partial vacuum environment, typically maintained at pressures between 40 and 80 millimetres of mercury and temperatures around 5 °C (40 °F).1
This method effectively extends the shelf life and maintains the quality of the fruit by reducing both respiration rates and the production of ethylene, a gas that naturally accelerates the ripening and senescence processes in many fruits. By lowering the atmospheric pressure, the storage environment slows the metabolic activities that lead to tissue deterioration, allowing for the preservation of high-quality fruit for several months.1
