【Abstract】 The optimum formula for the preparation of flavoured yoghurt from the submerged culture filtrate of Ganoderma lucidum as the major material was studied. The mixed fermenting agent was prepared, and the technological conditions for the processing of Ganoderma lucidum yoghurt were investigated and the nutrients in the yoghurt analyzed. Fresh milk and the submerged culture filtrate of Ganoderma lucidum were mixed at a ratio of 60 : 40, then 5% ～ 7% sugar, 0.2% PGA, 0.1% CMC-Na and 5% ～ 7% mixed fermenting agent were added. The mixture was fermented at 40 ～ 42℃ for 6 ～ 7 hours to give a new-type fermented yoghurt characterized by the high content of essential amino acids, fine mouth-feel and top quality.更多还原
