X-ray CT and porosity mapping to determine the effect of ‘Fuji’ apple morphological and microstructural properties on the incidence of CO2 induced internal browning

•Porosity maps of ‘Fuji’ apples were created from X-ray computed tomography images.•Internal browning (IB) occurred in the core of fruit after 3 d in 50 % CO2.•Larger fruit were more susceptible to IB incidence.•Porosity along the axial plane was generally lower for fruit that developed IB.•Coreline...
