This study enables to predict the quality of fresh mushrooms stored under isothermal conditions, using mixed models. The temperature dependence of these qualities further gives an insight to choose proper time–temperature management during storage. Storage under low temperature would delay the biological decay process and would extend the shelf life of the product. All the sensory characteristics were more influenced by individual consumer preference than the variation arise due to inherent biological variation. Quality is basically the perception of consumer mind. The sensory data analysis gave an insight to quantise the sensory characteristics instead of following a qualitative approach. These mathematical models can be useful in predicting the shelf life of fresh mushrooms under a temperature range of 3.5–15 °C, which is mostly used during distribution chain and storage of mushrooms, both at farm and retail outlets
