Active food packaging system with antioxidant properties based on green tea extract

Researchers from the University of Zaragoza in Spain have developed a formula including green tea extract (GTE) as an active food packaging material. This formula was moulded to obtain an independent component/device with antioxidant properties that could be easily coupled to industrial degassing valves for food packaging in special cases.
The results showed that the antioxidant capacity (scavenging of free radicals) of the new GTE-formula was 40% higher than the non-active system (blank). This antioxidant activity increased in parallel with the GTE concentration. An article about the research is published in Food Additives & Contaminants: Part A.
