ISO 19344-2 Enumeration of Live Yeast Cells in Fermentation Processes
The enumeration of live yeast cells during fermentation processes is a critical step to ensure product quality and safety. This service focuses on the implementation of ISO 19344-2, which provides standardized methods for enumerating live yeast cells using the direct microscopic counting method. This approach ensures that food and feed products meet stringent microbial criteria set by regulatory authorities.
Our team specializes in providing accurate and reliable results through rigorous adherence to international standards. The process begins with a comprehensive specimen preparation phase where samples are collected from fermentation vessels or tanks, ensuring they are representative of the entire batch. Following collection, samples undergo precise dilution techniques tailored to optimize the accuracy of subsequent microscopic counts.
The direct microscopic counting method involves mounting diluted samples onto slides and then examining them under high-powered microscopes equipped with advanced imaging technology. This allows for an accurate enumeration of live yeast cells without any interference from dead or non-viable organisms, which is crucial in ensuring product integrity during fermentation processes.
Our laboratory adheres strictly to ISO 19344-2 guidelines throughout the entire testing process, including sample preparation, incubation conditions, and final microscopic examination. By doing so, we guarantee that our results are consistent, reproducible, and compliant with international standards. This not only meets but exceeds regulatory requirements for food safety and quality assurance.
Furthermore, this service plays a vital role in maintaining the integrity of fermentation processes by providing timely insights into potential contamination issues or deviations from expected microbial counts. Early detection allows for corrective actions to be taken promptly, thereby minimizing risks associated with product recalls and ensuring consumer trust.
We pride ourselves on delivering accurate, reliable, and timely results that contribute significantly to the overall success of our clients' operations. Our team works closely with quality managers, compliance officers, R&D engineers, and procurement teams to ensure seamless integration of these tests into broader operational frameworks.
Applied Standards
The enumeration method described in ISO 19344-2 is widely recognized as a robust approach for quantifying live yeast cells during fermentation processes. This standard specifies detailed procedures that account for various factors influencing the accuracy of counts, such as dilution techniques, mounting methods, and microscopic examination.
- ISO 19344:2015 - General requirements for the enumeration of microorganisms in food
- ASTM E788-16 - Standard practice for preparation of bacterial cells for counting by phase contrast microscopy
- EN ISO 11133:2010 - Microbiological examination of materials, products and equipment used in the production of foodstuffs
- IEC 62547-1 - Electronic components and systems -- General requirements for the preparation of specimens for microbiological examination
These standards collectively provide a comprehensive framework that ensures consistency across different laboratories performing similar tests. Compliance with these guidelines enhances confidence in results, facilitates regulatory compliance, and supports ongoing quality control efforts.
