The sensory quality of mushroom samples, previously defrosted at 2e4C for 12 h, was evaluated directly after
freezing and after 8 months of frozen storage. The analysis of sensory parameters, conducted on a 5-point scale, was additionally supported by a quantitative descriptive analysis of colour (QDA) (ISO 13299, 2003). Mushroom quality was scored on a 5e1 scale (5¼excellent, 4¼very good, 3¼good, 2¼bad,1 ¼very bad) by a panel of five judges fulfilling the requirements for sensory sensitivity in Polish standardPN-ISO 3972 (1998). The lowest acceptable score for any characteristic assessed by the sensory panel was set at 3.0. Samples were evaluated in terms of: visual appearance, cell fluid leakage, colour, texture, taste and aroma. The coefficient of total sensory quality was calculated from weighted average indicator coefficients. The final value was obtained mathematically by dividing the total score obtained for the examined product (points relating to every indicator multiplied by their coefficients) by the sum of coefficients.
