In the dietary supplement and ingredient industry, protecting consumer health and meeting regulatory expectations are nonnegotiable. One critical aspect of quality control is residual solvent testing. Residual solvents, volatile chemicals used during manufacturing, can remain in products if not properly removed.
When evaluating fiber testing approaches, it’s important to review how results differ across sample matrices tested by both the new and previous methods. More laboratories are implementing the Rapid Integrated Dietary Fiber Methods - AOAC Official Methods 2017.16 and 2022.01. The AOAC 2017.16 method measures the insoluble fiber fraction (IDF) and soluble fiber fraction that precipitates in 78% ethanol (SDFP) together, and separately measures the soluble dietary fiber not precipitated in 78% ethanol (SDFS) by HPLC.
Postbiotics, defined as non-viable microbial cells, their components, or metabolites that confer health benefits to the host, represent a rapidly expanding frontier in microbiome research and functional ingredient development. Watch this webinar for a comprehensive look at the rapidly evolving field of postbiotics, combining cutting-edge science, global regulatory insights, and practical testing methodologies. Originally Aired on December 11, 2025.
In this blog, Dan Brouman traces MAHA’s path since December 2024, when the MAHA Caucus launched in Congress. Brouman also discusses MAHA’s future and its effects on food policy.
Selecting the right microbiological testing method isn’t just about speed or cost. It’s about risk management, product integrity, and regulatory compliance. Click to read about the strengths and limitations of different methodologies essential to avoid false negatives, regulatory citations, or costly recalls.
