发酵魔芋流质纤维饮料的研制

在纯魔芋培养基（ＫＤＡ）上接种６种菇类菌种，培养筛选出平菇菌为最佳发酵菌种。在５种发酵培养基上接种平菇菌进行摇瓶培养和深层发酵，获得最佳配方：１％魔芋粉＋２％玉米粉＋矿质元素。对其发酵液进行调配，获得发酵魔芋流质纤维饮料，流质纤维高达０．５％以上，无魔芋腥味，含较高的蛋白质、钙、铁、锌及菌体有益成分，香味自然，口味醇和，不易假冒。

DEVELOPMENT OF A FERMENTED KONJAC LIQUID FIBRE DRINK

Six mushroom species were inoculated on a KDA medium, and Pleurotus ostreatus was selected as the optimum mushroom species for konjac fermentation. Then Pleurotus ostreatus was inoculated on five different fermentation media for shaking flask culture and submersion culture, and an optimum formlation was obtained: 1% konjac powder 2% maize meal minerals. A fermented konjac liquid fibre drink was obtained which contained >0.5% liquid fibre and relatively high protein, iron, zinc and other healthy components, were free from the unpleasant smell characteristic of konjac and had natural aroma and mellow taste.
