Contrôle de l’aptitude à la transformation du lait cru au niveau de la laiterie « le littoral » Mostaganem

Abstract

The suitability of milk for processing is a problem for the milk producer and the processor. The producer will have to provide the processor with milk that will meet his expectations and the processor will have to have criteria for rapid judgment of the functional properties. The amount of the derivatives produced from a known quantity of milk is also of great economic importance for the dairy industry. In this study it is called to test the repeatability in the time of the milk processing aptitude tests (tests used on individual milks (of potential breeders) received at the Giplait-Esahel dairy, try to explain these aptitude tests with simple criteria of milk composition; stable elements and variable elements on the process ability of the milk received (repeatability spread over 4 weeks). Based on the results obtained and the evaluation of the marketability of the raw material; we will define the dairy recommendations and technological recommendations to implement by indicating the levers of control of industrial applications necessary to obtain safe and stable dairy products. The study found that technologically, our milk samples collected from farmers and from collectors is considered hygienically from a hygienic point of view as highly polluted and may jeopardize the smooth processing of milk processing operations. , especially during thermal treatments with a risk of clogging - coagulation of milk on heat exchangers and physical and biological standardization equipment requiring substantive work ranging from improved breeding practices, animal health, hygiene, good milking, picking and collection practices to control the quality and safety of our milk and dairy products.
