Improving the quality characteristics of rice mash grass carp using different microbial inoculation strategies
2021
Abstract The effects of different microbial inoculation strategies on the quality of Chinese traditional rice mash grass carp were investigated. Individual inoculation (Pediococcus pentosaceus 220, Staphylococcus xylosus 135, Saccharomyces cerevisiae 22), and mixed triple inoculation of the above strains (Pediococcus-Staphylococcus-Saccharomyces, PSS) were employed, including an uninoculated control. It was found that the inoculated microbes proliferated differently, depending on the inoculation regime. The decreases of pH, hardness, and increases of TCA-soluble peptides were accelerated, while the accumulation of TVB-N and TBARS was reduced in all inoculated groups. A significantly higher level of total free amino acids was found in PSS-inoculated grass carp (P
