🔍 Clinical, Sensory & Functional Diagnosis
Ponctuations et taches visqueuses jaune-orangé à brun-orangé en surface du fromage, accompagnées de notes oxydées et amères
🧬 Biochemical, Enzymatic & Genetic Mechanism
Synthèse intracellulaire de caroténoïdes hydroxylés (astaxanthine, adonixanthine, bêta-carotène) et activité estérase et aminopeptidasique
🌡️ Physicochemical Parameters & Target Matrices
Lavage du caillé, moulage et conservation réfrigérée (3 à 15 jours) • Contamination par les réseaux d'eau de laiterie (passage à travers certains filtres grâce à sa faible taille cellulaire), aérobiose stricte, pH supérieur à 5.3
🛡️ Cellar Protocol, Prophylaxis & Biocontrol
Entretien et remplacement régulier des membranes de microfiltration d'eau, désinfection UV/chlore des circuits et acidification lactique sous pH 5.2
