Description
Summary:•Dynamic controlled atmosphere maintain ‘Gala’ strains quality after long-term storage.•Ultralow oxygen maintain similar quality compared to dynamic controlled atmosphere.•Lowering oxygen down to 0.4kPa did not start ethyl acetate formation in apples.•Dynamic controlled atmosphere and ultralow oxygen storage reduced ethylene production. The aim of the present work was to compare the effect of ultralow oxygen (ULO) with dynamic controlled atmosphere (DCA) and controlled atmosphere (CA) on the post storage quality of ‘Royal Gala’ and ‘Galaxy’ apples after long-term storage. Two experiments were carried out with ‘Royal Gala’ and ‘Galaxy’ apples, in the years 2012 and 2013, respectively. A higher internal ethylene concentration was observed in fruits stored under CA; intermediate concentration in fruits under ULO; and the lowest by fruits stored under DCA-CF (DCA based on chlorophyll fluorescence). Flesh firmness was higher in fruits stored under DCA-CF and ULO differing from CA, in the year 2012, but in 2013 fruits stored under ULO showed the highest flesh firmness, differing from CA fruits. DCA-CF is efficient in quality maintenance of ‘Royal Gala’ and ‘Galaxy’ apples. Both ‘Gala’ mutants stored under ULO show a similar quality maintenance to those stored under DCA-CF.
