Figure 1. Puncture locations on apple equator. (1, 2, 3 - with skin; 1′, 2′, 3′ - without skin).
Figure 2. Load-displacement curve from puncture tests. Ft, bursting skin force; Fd, force corresponding to the elasticity limit of the flesh; Dp, displacement related to Ft; Dc, displacement related to Fd.
Figure 3. The puncture displacement and relative displacement of Golden Delicious apples during storage. a) and b) cool storage at 2°C and 96% relative humidity during 239 days. c) and d) forced ripening at 20 ± 1°C during 28 days. Error bars represent standard deviation of means for at least 20 apples.
Figure 4. The puncture force and relative rupture force of Golden Delicious apples during storage. a) and b) cool storage at 2°C and 96% relative humidity during 239 days. c) and d) forced ripening at 20 ± 1°C during 28 days. Error bars represents standard deviation of means for at least 20 apples.
Figure 5. The firmness and relative firmness of Golden Delicious apples during storage. a) and b) cool storage at 2°C and 96% relative humidity during 239 days. c) and d) forced ripening at 20 ± 1°C during 28 days. Error bars represents standard deviation of means for at least 20 apples.
Figure 6. The toughness and relative toughness of Golden Delicious apples during storage. a) and b) cool storage at 2°C and 96% relative humidity during 239 days. c) and d) forced ripening at 20 ± 1°C during 28 days. Error bars represents standard deviation of means for at least 20 apples.
Figure 7. Firmness properties of four apples varieties (Fuji, Granny Smith, Golden Delicious, Pink Lady) after a 210-day cool storage period. a) displacement; b); rupture force; c) firmness; d); toughness. Error bars represents standard deviation of means for 20 apples.
