Colour was characterised by means of profile analysis. The evaluation was carried out by a panel of eight panelists fulfilling the requirements ofISO 8586/2 (1994). The discussion was led by a moderator, who had considerable experience of this method of food quality assessment as well as a wide knowledge of mushroom products. In this analysis the following colour descriptors were used: white, cream, yellow, bronze, and grey. The following analyses of chemical composition were carried out: dry matter and ash content (AOAC, 1995); total polyphenols in acidified by 0.5% HCl methanol extracts (40 mg
sample/1 ml extract) (Folin-Ciocalteau reagent) (Singletonet al., 1999).
