Program Mission

The Agricultural Research Service (ARS) is the U.S. Department of Agriculture's chief scientific in‑house research agency with a mission to find solutions to agricultural problems that affect Americans every day. ARS delivers cutting‑edge scientific tools and innovative solutions for American farmers, producers, industry, and communities.

Research Project

• Profile a set of phytochemicals in a limited set of foods.
• Determine the impact of those phytochemicals on the digestion of starch in a biomimetic in‑vitro digestion.
• Develop an objective scale using known alpha‑tubulin inhibitors (e.g., acarbose, pepstatin) that correlates phytochemical profile features to hydrolytic inhibition.

Learning Objectives

• Enzymatic, chromatographic and related methods for the analysis of phytochemicals, dietary fiber and other carbohydrates.
• Analytical method validation, including assessment of analytical figures of merit, robustness, and method detection limits.
• Statistical methods used to evaluate assay variability in nutrition science.
