Spoilage Organisms: Early Detection for Stable Product Quality

Mold growth causing food spoilage — a source of quality loss and reduced shelf life.

Spoilage microorganisms are among the most important factors affecting food quality and shelf life. Their early detection helps identify potential quality defects such as off-flavours, gas formation, turbidity, texture changes and pH shifts before products reach the end of their intended shelf life.

We support food manufacturers and processors with the reliable detection, identification and assessment of spoilage organisms across a wide range of food categories, including dairy products, beverages, meat products and plant-based foods. Accreditation to DIN EN ISO/IEC 17025 provides the basis for scientifically robust results supporting shelf-life validation, process verification and quality assurance.
