Active modified atmosphere storage to preserve the quality of 'San Andreas' strawberries harvest at two ripening stages (original) (raw)
2020, Revista Brasileira de Fruticultura
This work was carried out to evaluate the effect of fruit ripening stage at harvest (“1/3 ripe” and “3/4 ripe”, respectively with 30% and 75% of red color) and passive modified atmosphere (MA) and active MA (with initial initial low O2 and/or high CO2) on quality of ‘San Andreas’ strawberries, with emphasis on bioactive compounds and metabolites of fermentative metabolism. The treatments evaluated were: control; passive MA [low density polyethylene (LDPE) packaging of 40 µm]; active MA with initial low O2 (1 kPa); active MA with initial high CO2 (30 kPa); and active MA with initial low O2 (1 kPa) and high CO2 (30 kPa). After 14 days of storage (0.5±0.2°C/92±2% RH) followed by two days of shelf life (20±5°C/65±10% RH), fruit weight loss was higher in control fruit. Soluble solids content and titratable acidity were not different between treatments. Fruit harvested “1/3 ripe” were firmer and had less intense red color after storage than fruit harvested “3/4 ripe”. Storage conditions d...
