🔍 Clinical, Sensory & Functional Diagnosis
Fentes précoces (slits) ou cavernes gazeuses dans les pâtes devant rester fermées, bombement des films sous-vide et texture parfois filante
🧬 Biochemical, Enzymatic & Genetic Mechanism
Co-métabolisme rapide du citrate (citrate lyase) et fermentation hétérolactique libérant du CO2, du diacétyle, de l'acétoïne et des exopolysaccharides
🌡️ Physicochemical Parameters & Target Matrices
Égouttage, début d'affinage et conservation sous film (2 à 30 jours) • Psychrotolérance (croissance dès 4-6 °C), dérive de proportion dans les levains mésophiles ou contamination sauvage, disponibilité en citrate et lactose
🛡️ Cellar Protocol, Prophylaxis & Biocontrol
Contrôle de l'équilibre souches acidifiantes / souches aromatiques du levain, maîtrise de la température d'égouttage et d'affinage (inférieure à 10 °C)
