AOAC 2018.05 Protein Digestibility Analysis in Dietary Supplements
The AOAC International Method 2018.05 is a standardized procedure used to assess the protein digestibility of dietary supplements, providing critical insights into ingredient quality and nutritional efficacy. This method evaluates how effectively proteins are broken down by digestive enzymes, which is essential for ensuring that dietary supplements provide optimal nutrition.
The analysis involves subjecting the supplement samples to simulated gastrointestinal conditions, including acid and enzymatic digestion, followed by quantification of undigested protein residues through colorimetric assays. Understanding digestibility helps manufacturers in formulating products that are easily absorbed by consumers, thereby enhancing product efficacy.
For quality managers and compliance officers, ensuring compliance with this method is crucial for maintaining the integrity of their products. R&D engineers can leverage these test results to refine formulations, while procurement teams can use them to verify supplier claims and ensure consistent ingredient quality.
The process begins with accurate sample preparation, which involves grinding the supplements into a fine powder using a laboratory mill or colloid mill, depending on the type of supplement. The sample is then suspended in an appropriate buffer solution containing digestive enzymes such as pepsin and trypsin to simulate gastric and pancreatic digestion.
After incubation under controlled conditions, the mixture undergoes filtration and colorimetric analysis using a spectrophotometer. This step quantifies undigested protein residues, which are indicative of the supplement's digestibility. The results provide a percentage value representing the proportion of ingested protein that is effectively digested.
Proper interpretation of these data allows for informed decisions on ingredient sourcing and formulation adjustments to meet regulatory requirements and consumer expectations. Compliance officers can use this information to ensure their products meet national standards like those set by the FDA or EU authorities, ensuring safe and efficacious dietary supplements.
