Résumé:
Milk plays a major role in nutrition for all ages, thanks to its balanced composition of basic elements. Physical, chemical and microbiological analyses are carried out to detect any alterations or contamination by germs that make milk unfit for consumption. The aim of our work is to contribute to the physicochemical and microbiological quality assessment of several milk samples from collectors of different herds. The results are compared with JORA 1998 and 2016 and AFNOR standards .
The results of the physicochemical analyses, i.e. T°, titratable acidity, density and fat content of all samples, were normal and in compliance with J.O.R.A. standards, as was the ATB test, which was negative on all samples. Microbiological analysis showed high levels of AMF, faecal coliforms, staphylococci, yeasts and moulds, which do not comply with current standards. On the other hand, all samples were free of salmonella .
To guarantee milk of good sanitary quality, it is essential to study all these parameters, which enable us to check compliance with regulations and assess the quality of milk in Algeria. Among other things, it is important to ensure farm management, maintenance of premises, animal feed throughout the rearing and collection of milk.
