Temperature effects on the internal lower oxygen limits of apple fruit

Harvest Date and Crop Load Effects on a Carbon Dioxide–related Storage Injury of `Braeburn' Apple

“…Skin permeance of four fruit from each orchard, harvest, crop load, and blush category was measured using a slightly modified version of the nonsteady state ethane efflux method (Banks, 1985) as described by Yearsley (1996). Briefly, 1 mL of compressed pure susceptibility; identification of these factors would increase confidence among marketers.…”

Maintaining optimal atmosphere conditions for fruits and vegetables throughout the postharvest handling chain

“…One possible explanation advanced by Beaudry et al (1992) is that the fruit skin's permeability to O 2 does not rise as rapidly as O 2 consumption increases with a temperature rise, leading to an increase in the lowest external O 2 concentration tolerated by the product. Although Boersig et al (1988) suggested, based on work with cultured pear fruit cells, that there may be a higher O 2 requirement for aerobic respiration at higher temperatures, Yearsley et al (1997b) found little effect of temperature on the internal LOL of apple fruit, save for a sharp increase above 28 8C.…”

“…Hertog et al (1998) presented a model of the fermentative CO 2 production with a competitive inhibition for O 2 and CO 2 and a temperature dependence according to Arrhenius' law of the model parameters. LOL values may also be determined based on internal O 2 concentration instead of the external value (Yearsley et al, 1996;Yearsley et al, 1997a;Yearsley et al, 1997b).…”

Quantification of microporosity in fruit by MRI at various magnetic fields: comparison with X-ray microtomography

“…Understanding of intercellular air spaces in relation to microstructural properties thus has important applications to understanding of several phenomena such as postharvest quality or shelf life of the fruit [3]. For example, apple fruit with greater fractional air volumes have been shown to be softer [4] or more mealy [5] and to have higher internal gas diffusion rates [6]. The volume of intercellular air spaces continues to increase during apple storage.…”
