Food Business Trends
What the exam tests
Food Business Trends tests how market, consumer, and channel forces shape product decisions. Expect data interpretation: share, growth, elasticity, margins, and category dynamics.
Core rules
- Market sizing: value versus volume; CAGR = (ending/beginning)^(1/n) - 1; share = brand sales ÷ category sales.
- Price elasticity: % change in quantity ÷ % change in price; elastic > 1, inelastic < 1. Promotion lifts volume but can erode margin.
- Channels: retail, foodservice, e-commerce, club, dollar, and private label; each has different margin, velocity, and packaging needs.
- Trends: health and wellness, clean label, plant-based, convenience, premiumization, value-seeking, sustainability, and personalization.
- Category management uses penetration, repeat rate, and basket affinity; private label grows in inflation.
- Gross margin = (price - COGS) ÷ price; contribution margin accounts for variable costs.
Worked example
A brand sells 2 million units in a 20 million-unit category: share = 10%. It cuts price 10% and volume rises 15%, so elasticity = 15 ÷ -10 = -1.5, which is elastic. Revenue rises 3.5%, but if COGS per unit is unchanged, gross profit may fall because each unit earns less. The decision must weigh margin dollars, not just volume growth. That is the business reasoning the exam rewards.
Traps
Confusing value and volume growth. Treating a niche trend as mainstream without penetration data. Ignoring private-label substitution. Assuming correlation in scanner data proves causation. Forgetting that foodservice and retail margins differ.
