Résumé

Mushrooms from the genus Pleurotus are tasty and rich in proteins, fibres, carbohydrates, vitamins and minerals. With about 90% of moisture, fresh mushrooms are very perishable, cooling being a good option for their preservation. In this work, the cooling of fresh mushrooms was investigated, with a focus on the cooling rate and homogeneity, as well as on mushroom weight loss during vacuum application. For each 3-4°C of temperature decrease, the weight loss was close to 1% of sample mass, due to the evaporation of product free water. Spraying with distilled water prior to cooling compensated the effective weight loss during vacuum application. Vacuum cooling is a simple and effective operation that demands moderate investments for small-scale operations, which is the case in most production units.
