The Complete Handbook of Snack Foods

Chapter 1: Understanding Snack Foods

Snack foods are a distinct product category defined by three characteristics: they are shelf-stable, ready-to-eat (or require minimal preparation), and designed to be consumed between meals in smaller portions than a full meal.

The category spans an enormous range of products. A bag of roasted almonds, a package of cheese crackers, beef jerky, a granola bar, freeze-dried fruit, and kettle-cooked potato chips all qualify as snack foods.

Understanding why this category exists, how it is manufactured and moved, and what pressures shape sourcing and pricing decisions is the foundation for every topic in this handbook.

Manufacturers could produce snack foods in centralized facilities, ship them long distances, and store them in retail environments without the cost and complexity of cold-chain logistics. Third, portion size and price point created a consumer behavior
