Increased concentration were also reported in winter squash (Cucurbita maxima), stored at 20 °C (Arvayo-Ortiz et al., 1994) and in sweet pepper stored for 21 days at 7.5 °C and for 3 days at 20 °C (Selahle et al., 2015). By contrast, tomato fruit stored for 21 days in the dark at 12–14 °C showed no change in fruit flesh β-carotene concentration (Liu et al., 2009).
