Weighted regression coefficients of cluster 2 for freshness parameters of Nile tilapia (Oreochromis niloticus) fillets stored at 4 ± 1 °C for 8 days by partial least square regression (PLSR). X axis = freshness parameters; Y axis = consumer purchase rejection (CPR). a*—redness; LOX—lipid oxidation; POX—protein oxidation; TR—torrymeter readings; TAMC—total aerobic mesophilic count; TAPC—total aerobic psychrotrophic count.
