摘要:

为有效控制产品的品质,从自然发酵的梅香鱼中分离筛选适合作为发酵剂的菌株,并研究不同菌种之间的配比对发酵产品品质的影响。结果表明,筛选出的嗜盐四联球菌(Tetragenococcus halophilus)、木糖葡萄球菌(Staphylococcus xylosus)及腐生葡萄球菌(Staphylococcus saprophyticus)符合发酵要求。与单菌株发酵及未接菌的对照组相比,3 株菌制得的混合发酵剂(比例为1∶1∶1)制备的发酵鱼感官上总体可接受程度最优,其咀嚼性和弹性也最高,并且组胺和挥发性盐基氮(total volatile basic nitrogen,TVB-N)的产生得到了有效抑制。该研究可为实现定向接种、人工控制以及规模化工业生产提供参考。

Abstract:

Bacterial strains from naturally fermented Meixiang fish, a traditional Chinese fish product, were isolated and
screened for their suitability to produce Meixiang fish as starter culture. Meanwhile, the influence of three selected strains
inoculated singly or in combination (1:1:1) on the quality of fermented fish. The results showed that Tetragenococcus
halophilus, Staphylococcus xylosus and Staphylococcus saprophyticus, all of which can meet the requirements for fish
fermentation, were separated from the naturally fermented fish. Compared to those fermented and not fermented with each
of the three strains, the fermented fish produced with their combination had the highest overall sensory acceptability and the
best chewiness and elasticity, and inhibited the generation of histamine and total volatile basic nitrogen (TVB-N). This study
can provide reference for targeted inoculation, manual control and large-scale industrial production of Meixiang fish.

Key words: Meixiang fish, fermentation, selection, quality
