| Abstract: |
This work aimed to investigate the potential of ozonated mist for microbiological disinfection and preservation of the physicochemical quality of strawberries. The experiments followed a completely randomized design with three replications. The assays consisted of six treatments: four with ozonated mist, one with ozone water, and one control group. In the mist treatments, ozone was input at 20 and 40 mg L−1 for exposures of 5 and 10 min. The ozone-water treatments used a concentration of 3.32 mg L−1, and the fruits were immersed for 5 min. The control corresponded to untreated fruits. The quality parameters appraised were mass-loss percentage, firmness, soluble solids content, pH, total titratable acidity, and color. The strawberries were stored in a refrigerated environment at 5 °C and 87% relative humidity. Ozonated mist proved more effective than ozone water in preserving the external appearance of strawberries and prolonging their shelf life, remarkably at 20 mg L−1. The effectiveness of ozonated mist in decreasing the aerobic mesophilic count surpassed that of ozone water, regardless of the concentration and exposure duration. Ozonated mist at 20 mg L−1 for 5 min proved to be the most efficient treatment to reduce the count of filamentous fungi and yeasts. [ABSTRACT FROM AUTHOR] |
