🔍 Clinical, Sensory & Functional Diagnosis
Lait et lactosérum filants en cuve, caillé mou mal égoutté, pellicule glaireuse incolore sur les fromages frais et rancissement précoce
🧬 Biochemical, Enzymatic & Genetic Mechanism
Synthèse de lipopolysaccharides et d'émulsanes capsulaires (bioémulsifiants de type alasan) et sécrétion de lipases/estérases thermostables
🌡️ Physicochemical Parameters & Target Matrices
Stockage du lait cru au froid, travail en cuve et conservation (0 à 10 jours) • Psychrotrophie (multiplication active à 4 °C), contamination par l'eau et les surfaces humides de laiterie, pH supérieur à 5.4
🛡️ Cellar Protocol, Prophylaxis & Biocontrol
Réduction du temps de garde du lait cru réfrigéré, traitement de l'eau de rinçage des cuves et acidification lactique franche
