Important features identified by partial least squares-discriminant analysis (PLS-DA) for sterile meat and meat inoculated with: (a) P. fragi (monoculture) and (b) Ln. mesenteroides (monoculture) stored at 4 and 10 °C. The color scale on the right represents the scaled abundance of each variable, with red color boxes indicating high abundance and green color boxes indicating low abundance.
