Abstract

Stored or packaged mushrooms have a very high metabolic activity, consuming O₂, producing O₂ and water as a result of their respiratory metabolism. A closed system methodology was employed to measure the O₂, O₂ respiration rate (RR) and the transpiration rate (TR) of mushrooms. The effect of storage temperature and the change of RR and TR during storage time were studied. After careful examination of the data of RR & TR on the mushrooms during storage, a linear model (for the O₂ and O₂ RR) and a Weibull model (for the TR of O₂ and O₂) were proposed to describe the primary model. Both RR & TR were dependent on the temperature of storage. The O₂ and O ₂ RR were found to have a significant linear increase with storage time. This pointed to the need to adjust storage conditions for these dynamic changes. The variability of the RR was also dependent on temperature indicating that the use of low storage temperatures is more beneficial in terms of having a homogeneous product than to slow the metabolic activity. An optimal temperature for minimise weight losses by transpiration was found at 6.4°C.
