Commodity Groups and Characteristics
Comparing major food groups by nutrients, storage, sensory properties, seasonality and theoretical use in meals.

Core concepts
Concept 1
The common commodity range includes cereals and starchy foods; fruit and vegetables; dairy; meat, fish and eggs; plant proteins; and fats and sugars.

Concept 3
Fresh, frozen, dried, canned and other processed forms can differ in convenience, cost, shelf life, sensory quality and nutrient profile.
Exam cue: Explain how storage or processing changes the commodity's suitability.
