Total Plate Count (TPC) / Aerobic Plate Count (APC)

 

Quantifying microbial load to define product freshness and operational excellence.

Total Plate Count (TPC) measures the overall microbial population capable of growing under aerobic conditions. At Weshin Inspection Tech , we follow international protocols (e.g., ISO, FDA BAM, AOAC) to provide accurate enumeration of total viable organisms, helping you establish a baseline for product quality and shelf-life stability.
 

The Importance of TPC Monitoring

 

As a general indicator of hygiene, TPC is fundamental to quality assurance and safety management:

  • Freshness Indicator: High TPC levels often correlate with product degradation, making it a primary metric for shelf-life studies and expiration dating.

  • Sanitation Verification: Regular TPC testing reveals the effectiveness of cleaning and disinfection protocols across your production lines.

  • Regulatory Compliance: Adhering to the specific microbial limits set by health authorities for food, beverages, cosmetics, and pharmaceuticals.

  • Process Integrity: Identifying spikes in microbial load to pinpoint potential contamination sources in raw materials or packaging stages.
     

Our Analytical Capabilities

 

Weshin Inspection Tech utilizes standardized microbiological techniques tailored to your product matrix:

  • Pour Plate Method: The gold standard for quantitative enumeration, ensuring uniform colony distribution and high reproducibility.
