The white mutant strain of Auricularia fuscosuccinea was processed through high-pressure steaming and used as an ingredient for the formuation of a dairy beverage. Optimization of the formulation for improved beverage stablity and sensory quality was carried out using single factor and orthogonal array design methods. The results indicated that after high-pressure cooking, the hardness, elasticity, cohesiveness and gumminess of the white Auricularia fuscosuccinea were decreased, and the chewiness was increased. The optimum formulation was found to consist of 40.0% white Auricularia fuscosuccinea juice, 0.1% citric acid, 4.0% soft sugar, 4.0% milk powder and 0.1% compound stabilizer. The formulated beveage had the best sensory quality and a pure flavor, and was verystable and highly nutritious.
