Partial replacement of fat and salt in liver pâté by addition of Agaricus bisporus and Pleurotus ostreatus flour

The effect of incorporation of 7.5% (hydrated 50/50 w/w) and 10% (hydrated 70/30 w/w) of Agaricus bisporus (Ab) and Pleurotus ostreatus (Po) flours as partial replacers of fat and salts (sodium chloride and phosphates) on physicochemical properties, microbiological and sensory properties of pâté was studied during cold storage. Mushroom flours increased moisture, dietary fibre and protein contents improving the nutritional value of pâtés. Mushroom flour influenced the colour parameters, especially Ab, and gave harder pâtés in 10% mushroom flour addition. Sensorially, the odour and taste of 7.5% of mushroom flour were considered acceptable, and its addition hydrated in a ratio 50/50 w/w should be the most suitable to improve the nutritional value of this product without significantly affecting the sensory properties. The addition of Ab and Po flours was a feasible strategy to replace fat and salts in pâté.
