The main aim of this work was to evaluate the final colour of the fructification bodies of the mushroom Agaricus blazei submitted to ascorbic and citric acid treatment. The mushroom Agaricus blazei was cultivated in an appropriated substrate and storage in incubators. The mushroom was harvested containing closed pileus and after cleaning with running tap water, the fruiting bodies were sliced and half of each were submitted to acid treatment and half was the control (water immersion). The experimental treatment consisted of immersing half of each basiodiocarp in different concentrations of the commercial solution of ascorbic acid (0, 10, 20 and 30 mg/ml during 0, 2, 5, 10, 15 and 20 minutes). The other parts of fruiting bodies were also tested in the same concentrations of citric acid for 0, 10 and 15 minutes. All the treatments were done in 3 replicates. According to the Munsell colour scale it was not observed difference in the colour of the basidiocarps among the treatments used in this work.
