Abstract
The interrelationships of the chemical constituents in 551 human milk samples were analysed statistically. Correlation coefficients and regression equations of 19 pairs between 16 constitu-ents were calculated.
Significant positive correlations were found between total nitrogen compounds content andtitratable acidity, between total nitrogen compounds content and ash content, between totalnitrogen compounds content and phosphorus content, between protein content and titratableacidity, between protein content and nonprotein nitrogen compounds content, between proteincontent and ash content, between protein content and phosphorus content and between caseincontent and phosphorus content. Significant negative correlations were found between pHvalue and titratable acidity, between fat content and specific gravity, between fat contentand solids-not-fat content, between total nitrogen compounds content and pH value, betweenprotein content and pH value, between casein content and serum protein content and betweenash content and pH value.
