Oxygen scavenging polymer coating prepared by hydrophobic modification of glucose oxidase

摘要: Trace oxygen in packaged foods, beverages, and pharmaceuticals can promote a range of oxidative degradation reactions support microbial growth, ultimately impacting product quality shelf-life. Oxygen scavenging active packaging systems have therefore been explored to control headspace content. Herein, we report on hydrophobic ion pairing method render glucose oxidase hydrophobic, thus soluble organic solvents. Hydrophobic modified was blended with ethylene vinyl acetate cast the interior glass vials demonstrate potential as commercially translatable coating for enzyme immobilization. The resulting polymer coatings were topographically uniform presented 0.553 μg/cm2 at interface. effectively reduced by 2% closed-vial system filled 50 vol% citrate buffer, pH 3.5. Less than 25% protein migrated from over an 8-week leaching study, no detectable leached first 4 weeks. enabled facile, high-throughput immobilization technique without use complicated, time-consuming surface modification chemistries reagents. Such controlling goods, retaining stability oxygen-sensitive components such colors, flavors, nutrients.
