Apply deep knowledge of milk composition and how processing impacts chemistry, physical properties, and functional performance of milk and its components. Partner with Product Development and Operations on formulation/processing choices for fluid dairy products, including shakes and other forms (sensory, taste, texture, stability, shelf‑life). Define plans and execute and interpret analytical testing results tied to processing and shelf‑life. Establish and improve SOPs, troubleshooting playbooks, and process data reviews.
