Crisps

Crisps are savoury bagged snacks made from thinly sliced vegetables, classically potatoes, or from extruded cereal pellets, fried and flavoured; in some countries they are called chips. Frying dehydrates the slice to a brittle crunch while developing roasted flavour, and seasonings from salt and vinegar to complex spice blends are applied after frying. Process control targets slice thickness, frying temperature, and oil quality to manage texture, fat content, and acrylamide formation. Nitrogen-flushed packaging protects against oxidation and crushing through distribution.
