Discover how Neotron ensures mozzarella meets top standards in microbiology, allergens, and nutritional analysis.
Mozzarella is one of Italy’s most iconic cheeses, celebrated worldwide for its delicate taste, creamy texture and versatility. Behind its simplicity lies a complex product that requires strict testing to guarantee safety, nutritional value and authenticity. We provide advanced chemical, microbiological, allergen and authenticity testing to support producers, protect consumers and preserve the reputation of Italian mozzarella.
The chemical analysis of mozzarella focuses on evaluating its safety, quality and authenticity through a detailed study of its composition.
Nutritional Composition
Standard nutritional analyses provide the foundation of mozzarella’s macro labelling and include:
- Moisture
- Fat content
- Protein
- Ash (total minerals)
- Carbohydrates (by calculation)
Additional advanced investigations can further define its nutritional profile:
- Fatty acids: Determined by GC techniques to study the balance between saturated, mono- and poly-unsaturated fats.
- Proteins and amino acids: Both total content and free amino acids are analyzed to assess protein breakdown during processing and storage.
- Furosine: A marker of the Maillard reaction, useful for assessing protein damage and nutritional quality linked to heat treatments.
- Minerals: ICP-OES techniques measure calcium, phosphorus, sodium and other essential minerals.
- Carbohydrates: Free sugars, primarily lactose, are tested via HPLC. For “low-lactose” claims, LC-MS allows the detection of trace sugar levels.
Other key quality parameters such as pH, salt content, lactic acid concentration and titratable acidity provide further insights into mozzarella’s flavor, texture and shelf life.
Microbiological Testing
As a fresh stretched-curd cheese, mozzarella is highly perishable and supports the growth of a wide range of microorganisms. Beneficial bacteria such as streptococci, lactobacilli, enterococci and yeasts contribute to flavor and texture, but monitoring is essential to prevent contamination.
Our microbiological testing ensures mozzarella remains safe and stable by checking for:
- Indicators of hygiene (e.g. Escherichia coli)
- Pathogenic bacteria (e.g. coagulase-positive staphylococci)
- Spoilage microorganisms, notably Pseudomonas fluorescens, a Gram-negative bacterium that causes flavor, odor, color and texture defects, including the blue streak phenomenon.
To guarantee product safety, we apply both traditional microbiological methods and molecular tools such as Sanger Sequencing of the 16S rRNA gene. This enables precise identification of microbial populations in both the product and the production environment.
Allergen Testing
Allergen management is a critical aspect of global food safety. Although milk is the primary allergen in mozzarella, cross-contamination risks exist when other allergenic ingredients are present in production facilities.
Our allergen testing services include:
- Screening for major allergens such as nuts, soy, celery, sesame, mustard and lupin.
- Gluten detection for celiac safety using ELISA techniques.
- Flexible testing platforms including ELISA, Real-Time PCR and Droplet Digital PCR, allowing us to tailor analyses to each client’s needs.
This comprehensive approach ensures that mozzarella is tested with the same rigor as multi-ingredient food products, reinforcing consumer confidence.
Authenticity and Food Fraud Prevention
Authenticity is especially vital for products with Protected Designation of Origin (PDO) status, such as Mozzarella di Bufala Campana DOP. Protecting these traditional products from fraud is essential for safeguarding both producers and consumers.
We apply Next Generation Sequencing (NGS) technologies to verify product authenticity. This powerful technique allows us to:
- Detect adulteration of raw materials, such as the presence of cow’s milk in 100% buffalo-labelled products.
- Confirm compliance with PDO standards.
- Provide high-resolution insights into DNA composition for traceability and fraud prevention.
From nutritional composition and microbial quality to allergen safety and authenticity verification, we provide a comprehensive suite of mozzarella testing services. By combining advanced analytical technologies with decades of expertise, we help the dairy industry maintain the highest standards of safety, quality and consumer trust.
