Sažetak
Agaricus bisporus, known as white button mushroom or champignon, is the most cultivated mushroom. Its good nutritional characteristics due to the low fat, high protein and carbohydrate content, among which dietary fibers are predominant, make this mushroom almost ideal dietary foodstuff. In addition, it contains a great deal of antioxidative substances as well as polysaccharides, such as beta-glucan, which has been reported for its immunomodulatory activity. Waste champignon biomass, containing mainly lower parts of champignon stalks, is a secondary product which is gained during the harvesting stage. Although this material is edible, there is not a suitable market for its distribution in Croatia. In order to explore the possibilities of using the waste biomass, its antioxidative potential was analysed using three different methods. Compared to fresh table A. bisporus intended for Croatian market, a lower antioxidant properties may be noticed in the waste biomass. It was probably caused by degradative changes which have occurred during the storage, or by an uneven distribution of the antioxidative compounds between the various parts of the mushrooms since the waste material mainly consisted of stalks and not of whole fruiting bodies. Portions of total phenols and flavonoids important for antioxidative properties were also analysed. FT-IR analysis was used to characterise the presence of compounds that cause antioxidative activity. The obtained results showed that the waste biomass of A. bisporus could be used as a source of antioxidants.
