COA
COA (Certificate of Analysis) is a document that food processing companies use to verify the quality and safety of their products. Think of it as a report card that shows all the important tests done on food items. This document helps companies prove that their products meet safety standards and customer requirements. When someone mentions COA in their resume, they're usually talking about working with these quality check documents, either creating them, reviewing them, or using them to make sure products are safe to sell.
