All data are reported as means of relative percentage of total fatty acids (n = 3); CTR: control cheese; TRT: experimental cheese; T0: time 0; T30: 30 days of ripening; (Z) zinc treatment, (T) time and (Z × T) time and zinc interaction. RMSE: root mean square error. SFA = Saturated Fatty Acids; MUFA = Monounsaturated Fatty Acids; PUFA = Polyunsaturated Fatty Acids; CLA = Conjugated Linoleic Acids; Δ = Desaturation Index. ΔC14 = C14:1/(C14:1 + C14:0); ΔC16:1 = C16:1/(C16:1/C16); ΔC18:1 = C18:1/(C18:1 + C18:0); ΔCLA = CLA/(CLA + C18:1, t11); ΔCLA = (CLA/(C18:1, t11 + CLA)] × 100; AI = (C12:0 + 4 × C14:0 + C16:0)/(MUFA + PUFA(n3, n6); TI = (C14:0 + C16:0 + C18:0)/(0.5 × MUFA) + (0.5 × PUFAn6) + (3 × PUFAn3) + (n3/n6).
