The effects of moisture, amount of transition metal, and thermal processing on oxygen scavenging capability were also investigated. Our results showed that ?-tocopherol and transition metal had 6.72 cc O2\/g oxygen scavenging capacity and 0.11 cc O2 \/g?day oxygen scavenging rate. Nanoencapsulation technology was adopted for the possible oxygen scavenging activation system. ?-tocopherol-loaded poly ?-caprolactone (PCL) nanoparticles were prepared by O\/W emulsion solvent evaporation with ultrasonication. The effect of PCL concentration, solvent in oil phase, and ultrasonication time on encapsulation efficiency (%), particle mean size, and loading (%) were investigated. Overall, 5% PCL in methylene chloride (DCM) as solvent in oil phase with 3 min ultrasonication time showed the best encapsulation formulation and this formulation was selected for the further research. ?-tocopherol-loaded nanoparticle and transition metal in scavenging mixture was evaluated as a heat activated oxygen scavenger.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51929694896416,"sku":"NEW3639243412","price":96.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/miakarts.com\/products\/oxygen-scavenging-nanoparticle-tocopherol-and-transition-metal-in-scavenging-mixture-3639243412","provider":"Miakarts Books","version":"1.0","type":"link"}
