This document discusses oxygen scavenging technologies used to prevent oxidation and extend the shelf life of packaged foods. It describes various oxygen scavenging methods including ascorbic acid oxidation, catechol oxidation, enzymatic oxidation, and iron powder oxidation. Factors that affect the choice of oxygen scavenger are discussed, as well as conditions required for oxygen scavengers to be effective. Examples of oxygen scavenging technologies applied to sachets, films, bottle closures, and labels are provided. The economic benefits of using oxygen scavenging packaging include increased shelf life, reduced distribution losses, and decreased costs.

Problem-should not react with atmospheric oxygen before use. Solution: By 1. Illumination 2. Catalysis 3. Reagents Examples: 1. OS1000 2. Zero2 3. Oxyguard LABELS It is iron-based oxygen scavenging label having printable surface and it is acceptable for food contact. It will remain in adhesion to food package. It is resistant to fat and moisture. Examples: Freshmax- Multisorb Technology BOTTLE CLOSURES Removal of oxygen from bottle by crowns, cans, plastic and metal closures. It is based on ascorbic acid oxidation. Examples: Darex Oxygen Scavenging Technology
