The precise analysis of particles in powders, emulsions, and suspensions is crucial in the food, beverage, and nutraceutical industries, not only for the design and quality of products but also for consumer health. Similarly, analyzing the release of particles from packaging materials is essential to ensure safety and maintain the integrity of the product. The Classizer™ ONE stands out as an indispensable asset in these activities, providing accurate, added value, and reliable data that is vital for the development of high-quality food and beverage products and for safeguarding public health. Its advanced SPES/SPES² technologies and ease of use make it a fundamental tool for industry professionals committed to excellence in product design and quality assurance.

Example of application: mayonnaise
Mayonnaise is a thick, cold, and creamy sauce made with an emulsion of oil, egg yolk, and either vinegar or lemon juice as an acid. 

REAL MAYO. An effective refractive index of about 1.48 is measured in agreement with the expected values.

Example of application: probiotics analysis
Probiotics are live helpful microorganisms that are intended to have health benefits when consumed. They can be found in yogurt and other fermented foods, dietary supplements, and beauty products. Results here presented are of a probiotic product mabe by a liquid mix of bacillus clausii and microcrystalline cellulose employed for the management intestinal bacterial flora. The product is advertised to contain 4 billion of live lactic ferments per vial (5mL vial, corresponding thus to an expected numerical concentration of 8E8 probiotic/mL). It is known to also contain a population of micronized cellulose. Two separate clouds are observed and correspond to two population of particles in the sample. The EOS Classizer™ software easily classifies and analyzes the two clouds providing information on the optical properties, size and numerical concentration of each population.

Example of application: particles release from food containers
A growing body of literature is raising concerns about the spread of nano- and microplastics and the hazards they pose to the environment and on human health. Classizer ONE is a key added-value solution for studying the release of sub-micrometric plastics in water by polypropylene containers certified for alimentary use is described. The results here reported show evidence of negligible release when the temperature of the water is kept below the manufacturer’s specifications, whereas a rampant increase occurs beyond these conditions, irrespective of the thermal history of the sample. Particles with a diameter distribution that spans one order of magnitude are observed, ranging from ≈200 nm to 2 µm, and their refractive index and shape is characterized with light scattering measurements.
