Avg score: 0% Most missed: “MAP and CAP are the same packaging techniques.”
Topics include: Food active packaging, intelligent packaging systems, modified and controlled packaging techniques. Active food packaging is a concept that aims to extend a product's shelf life. Some examples of active food packaging include: Antimicrobial packaging: Reduces, inhibits, or delays the growth of pathogenic microorganisms in packaged food and packaging materials. Oxygen scavengers: Absorb oxygen to remove it from the packaging and extend the shelf life of food products. CO2 emitters: Actively produce and release carbon dioxide within the package to inhibit spoilage and... Show more
