FDA's factored food vocabulary for food product description

The Food and Drug Administration's Factored Food Vocabulary (FFV) uses standardized language to describe characteristics of food products that are important for food safety and nutritional quality. Each food product is described by a set of descriptors from the following factors: product type; food source; part of plant or animal; physical state, shape, or form; degree of preparation; cooking method; treatment applied; preservation method; packing medium; container or wrapping; food contact surface; and user group. The purpose of the vocabulary is to facilitate retrieval of food composition, food consumption, food contamination, and other food-related data relative to these factors. The major advantages of this system are flexibility with specificity, enhanced searchability with economy, and ease of change and updating.
