The Difference Is Usually Usage, Not A Legal Definition
"Food flavoring" and "food flavor" often overlap in supplier conversations. A buyer may use one term in an initial request and the other in a later email. That does not automatically change the technical request.
Food flavoring tends to sound like a material that will be added to a finished product. Food flavor can sound broader: a sensory profile, a category, a food-grade flavor item, or a supplier's range. "Food flavors" is commonly used when buyers are exploring several profiles or application groups.
Country, industry, company, and individual purchasing habits all influence the wording. Treat the terms as wording preferences, then rely on the product brief for technical meaning.
