Environmental and final product testing alone will NOT ensure food quality or food safety. Spoilage or pathogenic contaminants can be introduced into the plant with raw milk (e.g., psychrotolerant spore formers) or the production process (e.g., gram-negative bacteria, psychrotrophs, pathogens). It is critical that sampling and testing for spoilage and pathogenic contaminants be fast and simple to ensure ongoing quality.

Microbial or pathogenic contamination can become established at any point in the process from the environment, biofilms, or cracks or pinholes in stainless steel. Critical control points (CCP) can validate and verify that sanitation and hygiene protocols meet specifications across the process. Without regularly collected and accurate inline data to identify trends, you cannot identify whether microbial counts develop over time and proactively adjust when necessary.

Improve offloading efficiency and safety by taking samples from the ground with the QualiTru side port. Help ensure you have a fair payment sample. Accurate and representative samples reflect the entire volume or load and eliminate issues with stratification.

Fair payment starts with confidence in the sample collection process. Representative sampling reflects the entire volume or load, which eliminates issues with stratification. The QualiTru system helps ensure accuracy from start to finish.

Inline contamination from raw products, biofilms, cracks in equipment or poor sanitation procedures can impact Quality bonus payment. Aseptic sampling on silos, milking robots and other equipment can highlight variations in your process sanitation and potential contamination.

String sampling for components at the pen level, rather than individual cow testing, can save time and reduce testing costs.

Some farmers use string sampling for somatic cells at the pen level, rather than individual cow or bulk tank testing to check for mastitis.

Wort is susceptible to contamination during knockout leading to off flavors. An aseptic sample allows you to accurately identify an issue before fermentation.

Water quality entering the plant or reused may have different standards; with an aseptic sample you can be confident that your quality meets specifications.

Beer, juice, and other liquid products are susceptible to off flavors due to chemical or microbiological contamination. Aseptic sampling helps ensure consistency in product quality.

Without accurate yeast cell counts you risk over or under pitching into the wort. Under pitching can result in off flavors and over pitching can adversely affect the health of the next generation of yeast. To get an accurate cell count, you must have an accurate sample.

Without accurate sampling, you cannot reliably tell when fermentation is complete. Ending fermentation early can result in off flavors in the finished product.

Contamination can enter your process from biofilms cracks, pinholes and the environment. Aseptic sampling allows you to identify issues early and maintain consistent product quality.

Improve offloading efficiency by taking the Appendix N sample from the ground with the QualiTru Adjustable Tanker Port.

Taking a sample from the top of the truck can be dangerous for employee safety. A sample from the side of the truck can prevent falls as well as prevent contamination from entering the truck.

Contamination can enter your process from biofilms, cracks, pinholes and the environment. Aseptic sampling allows you to identify issues early and maintain consistent product quality. Use QualiTru’s single use TruStream collection bags and TruDraw Sterile Single Sampler collection containers for aseptic sample collection from research and experimental development (R&D) through Good Manufacturing Practices (GMP).

Water quality entering the plant or reused may have different standards. An aseptic sample helps ensure confidence that your quality meets specifications.

What Our Customers Say…

Having an aseptic sampling process, our team can be confident that our test results are accurate to our product. We rely on QualiTru sampling ports throughout our process to gain better control of product quality on the front end. Not only do we have better control, but we save money from our previous style of sampling valve when we release the product before collecting.

Finished product sampling provides a global overview of the production but is of very limited interest for root cause analysis in case of deviation. This is where inline sampling is needed, to track the deviation at its source. As one needs to be intrusive in an often closed process, it is paramount to perform aseptic sampling: protecting both the factory sample for further analysis and the production process.

QualiTru Sampling Systems products gave us an internal confidence in verifying that our filtering system meets our aseptic targets. Plus, it satisfied our local government agencies with our processing parameters. We can see a benefit to expanding the use of QualiTru septa to many more areas within our plant for use in a wider range of temperatures for ease of use and complete plant standardization.
