In this thesis, effects of common factors in yeast extract production with autolysis on yield and total amount of amino acid nitrogen in supernatant, degradation of RNA and saccharides during autolysis were studied, in which fresh baker\'s yeast was used as material. Extraction of 5\'-phosphodiesterase from barley rootlets was also studied. The optimum technology conditions of yeast extract production was determined by comprehensive considering results of above-mentioned study.

本论文以新鲜面包酵母为原料，研究了自溶法生产酵母抽提物过程中的影响因素对得率、上清液氨基氮总量、自溶过程中RNA降解及糖类物质降解的影响，同时还对麦芽根中5'-磷酸二酯酶的提取进行了研究，综合以上研究结果优化了酵母抽提物生产的工艺条件；此外，从酵母自溶残渣中提取了酵母细胞壁多糖，并对该多糖的乳化性及酯化修饰进行了研究，取得了下述主要研究结果。1。
