  • a h is the shoulder time (see Materials and Methods for description). When no shoulder time is observed, there is no h, and the model is reduced by this parameter.

  • b yend is the ending aysmptote (see Materials and Methods for description). When no final asymptote is observed, there is no yend, and the model is reduced by this parameter.

  • c Maximum decay rate estimated by the Baranyi-Roberts model converted to log-linear decay rate day−1.

  • d Decay rate calculated by Chick's law by linear regression; only the linear portions of decay curves were utilized.
