Easy & Efficient Amino Acid Sample Prep followed by Accurate Detection - a look at Wet and Dry Pet Food

Amino Acid Analysis is required in many applications related to foods, dietary supplements and animal feeds and is a fundamental tool for monitoring product QC and compliance with nutritional labeling.

AOAC International has recently published a standardized method (AOAC Official Method 2018.06) for the analysis of total amino acids in infant formulas and adult nutritionals by UHPLC-UV. For some samples, to obtain a full amino acid profile, the samples must first be hydrolyzed. Due to the varied properties of amino acids and diversity of sample matrices, hydrolysis, separation and detection represents an analytical challenge. Learn more about effective hydrolysis, separation and detection of amino acids in dietary supplements, plant-based meats, and pet food during a 3-part webinar series with CEM and Waters.
