Abstract

Respiration rate is an important factor related to rates of quality change of fresh produce. In this study, three chilli cultivars, 'Paprika' (Capsicum annuum), 'Jalapeno' (Capsicum annuum) and 'Habanero' (Capsicum chinense) sourced from a commercial grower in New Zealand were used to study the relationship between temperature and respiration rate. Fruit were stored at 0, 4, 8, 12, and 20ºC and respiration rate was measured as carbon dioxide (CO2) production at 7 day intervals until the end of storage. Respiration rate increased exponentially with increased storage temperature for all three cultivars although each cultivar was influenced differently by temperature. The highest respiration rates of 0.38, 1.03 and 2.74 mmol (CO2)kg-1h-1 for 'Jalapeno', 'Habanero' and 'Paprika' respectively were measured for fruit stored at 20ºC. Ethylene production was not detected for all three cultivars during storage. An Arrhenius based respiration model was developed to describe the dependence of respiration rate on temperature.
