[Response] Thanks for your comments. We have revised it in the Manuscript. The BP-ANN had achieved excellent predictive performance (R2 > 0.9) for the TPC, TGP, THP, AV, PV conventional indexes during frying process. The R2 higher than 0.9 in the model indicated excellent classification performance as well as prediction ability (Cavanna, Righetti, Elliott, & Suman, 2018).
