Statistical analysisData were analysed using the Generalized Linear Model (GLM)procedure of statistical software (XLSTAT 2011, v5.01, Addinsoft,Barcelona, Spain). The data was analysed using the linear mixed modeland included nitrate reduction and storage time as fixed effects, andreplicates as random effect. The interaction between fixed effects wastested, and it was not significant and was excluded from the model. Thereplication was not significant (P > .10) for any of the traits. Whensignificant effect of the treatment group was detected (P < .05), leastsquares means (LSM) were compared using Tukey test. Principal component analysis (PCA) was done to evaluate the relationships amongsausage formulation (nitrate reduction), storage time and differentparameters (pH, water activity, TBARS, protein and fat content, nitrateresidual, colour, microbiota and volatile compounds).to the higher value of hardness. Thus, the addition of CPC at 1.5% and2.5% caused the change in textural parameters of resulted sausage,especially hardness, due to the formation of CPC-meat protein matrix.
