Shelf life of vacuum impregnated new potatoes stored under modified atmosphere packaging

The aim of this study was to investigate the shelf life of vacuumed impregnated new potato cubes treated with solutions of 3% salt substitute-SS, 2% ascorbic acid-AA, 0.2% calcium chloride-CC, and 2% calcium ascorbate- CA. The samples were packaged into 90 µm and 130 µm PA/PE bags under different low oxygen modified atmospheres (with 5, 10% or without air/30% gas mixture: 95% N2, 5% CO2). During 12 days of storage at 4 °C, the concentration of O2 and CO2 in the packaging headspace was monitored, as well as the colour and firmness of untreated and treated potato cubes. The analysis of some chemical composition parameters (total and soluble dry matter, content of sodium chloride, phenolic compounds), as well as microbiological analyses (aerobic mesophilic bacteria-AMB, aerobic psychrophilic bacteria-APB, yeast and moulds) were carried out on “0” and on day 6 and day 12 of storage at 4 °C. The potato cubes treated with the combination of 3% SS, 2% AA, and 0.2% CC, packaged in 130 µm PA/PE bags under 5% air and 30% gas mixture (95% N2, 5% CO2) recorded the best results regarding all the analysed parameters and minimum spoilage compared to other treatments. AMB and APB counts in these samples after 12 days were even below the permitted levels for fresh vegetables (<104 CFUg-1).
