Description
Summary:The objectives of this work were to evaluate the possibility of using coffee grounds for cultivating Pleurotus ostreatus mushrooms and determine the nutritional composition of Pleurotus ostreatus mushrooms produced on coffee grounds substrate. The results revealed a good fruiting of the fungus on coffee grounds and the biological effectiveness (weight of fresh mushroom) reached about 97% after 30 days. We determined the total protein content in vitamin C, the total polyphenols and the activity of Polyphenol oxidases (PPOs) enzyme on 32 samples of fresh Pleurotus ostreatus mushroom (cap and stem) and subjected to heat treatments (blanching, boiling and freezing). The protein content was ranged between the values of 16.9 and 25.1g/ 100g and the Vitamin C content within the range of values presented 64.32-564.95 mg/100g. The polyphenol content results varied significantly in the analyzed samples varying between 1.887 – 7.667 mg GAE / 100 g vegetable product. The determination of the polyphenol oxidase enzyme responsible for enzymatically blackening of the fungus presented values in the range 0.274- 0.610mg / 100g.
