Table 1 Effect of heat treatment and preservative use on Hp, M-SAA3 and CRP values in bovine milk

Protein	Treatment	Significant difference P	Regression equation in the form of y = c + mx^a	Correlation coefficient R^2/P
Hp	Heat n = 59	0.066	Heated Hp = 13.05 + 0.76 x unheated Hp	0.85/P < 0.001
SAA	Heat n = 44	0.000	Heated SAA = 38.6 + 0.28 unheated SAA	0.925/ P < 0.001
CRP	Heat n = 53	0.007	Heated CRP = −57.69 + 0.61 unheated CRP	0.932/P < 0.001
Hp	Potassium dichromate n = 35	0.080	Treated Hp = −270 + 1.04 non treated Hp	0.982/P < 0.001
SAA	Potassium dichromate n = 18	0.363	Treated SAA = −0.30 + 0.99 non treated SAA	0.642/P < 0.05
CRP	Potassium dichromate n = 20	0.003	Treated CRP = 5.41 + 1.47 non treated	0.913/P < 0.001
Hp	Bronopol n = 54	0.155	Treated Hp = 52.4 + 0.95 non treated Hp	0.882/ P < 0.001
SAA	Bronopol n = 21	0.088	Treated SAA = 1.10 + 0.0005 non treated	0.262/P > 0.05
CRP	Bronopol n = 21	0.028	Treated CRP = 2.15 + 0.96 non treated	0.765/P < 0.001
