question 20: Flesh changing colour when cut and exposed to air
Some compounds contained in mushrooms react to the oxygen of the air and induce a colour change of the flesh as soon as it is exposed to air. To highlight this property, we just have to cut the mushroom into two pieces, look for a potential colour change of the flesh immediately when it is cut, and check again after a few minutes upon exposure to air.
if we don't see any colour change at all, we must also indicate it in this section. Make sure that you let a few minutes go by before checking the colour again and answering this section of the questionnaire.
