摘　　要：为了确定人工发酵蜂粮的发酵方式,对固态发酵和液态发酵的蜂粮的乳酸菌活菌数、感官评分、总糖、总蛋白以及氨基酸含量进行测定。结果发现,液态发酵的蜂粮中的乳酸菌活菌数多于固态发酵,且其营养成分也优于固态发酵。固态发酵的蜂粮的乳酸菌活菌数最大值为1.65×10^7CFU/g,感官评分为4.02分,总糖含量为45.9%,总蛋白含量为23.9%,总氨基酸含量为1.52 g/100 g。液态发酵蜂粮的活菌数达到2.12×10^7CFU/g,感官评分为4.44分,总糖含量为46.8%,总蛋白含量为24.3%,总氨基酸含量为1.54 g/100 g,尤其天冬氨酸、苏氨酸、谷氨酸、异亮氨酸、亮氨酸、苯丙氨酸含量较高。结果表明,蜂粮液态发酵方式优于固态发酵,可以用液态发酵进行蜂粮的大规模生产。In order to explore the artificial bee bread fermentation way, the viable count of lactic acid bacteria, sensory score, total sugar, total protein and total amino acid content of bee bread by solid-state and liquid-state fermentation were determined. The results showed that the viable count of lactic acid bacteria in the bee bread with liquid-state fermentation were more than that in the bee bread with solid-state fermentation. The maximum number of viable bacteria in the solid-fermented bee bread was 1.65×10^7 CFU/g, the sensory score was 4.02, the total sugar content was 45.9%, the total protein content was 23.9%, and the total amino acid content was 1.52 g/100 g. The viable count of lactic acid bacteria of bee bread with liquid-state fermentation reached 2.12×10^7 CFU/g, the sensory score was 4.44, the total sugar content was 46.8%, the total protein content was 24.3%, and the content of total amino acids was 1.54 g/100 g, especially aspartic acid, threonine, glutamate, isoleucine, leucine and phenylalanine were high. The results showed that the bee bread with liquid-state fermentation was superior to that of solid-state fermentation, which could be used for large-scale production of bee bread.
