“…The use of plastic-based packaging materials in food packaging has raised concerns over human health due to the presence of carcinogenic ingredients in it and are posing a severe threat to land and oceans as well. In order to overcome these issues and to establish a sustainable world, United Nations Environment Program (UNEP) has framed Sustainable Development Goals (SDGs) as an agenda for 2030. − Packaging manufacturers and scientists across the globe are developing alternative sustainable and green materials for environmentally friendly packaging practices. − …”

Food scarcity and safety are the utmost considerable issues of the modern world and need to be addressed with environmentally benign approaches. Green and sustainable synthesis of polymyrcene from β-myrcene via emulsion polymerization and its applicability as an oxygen scavenging material have been studied. The synthesized polymer was activated by using ultraviolet (UV) light in order to trigger the oxygen scavenging mechanism. The synthesized polymer was characterized for its molecular weight by chromatography, thermal study, and structural changes by infrared spectroscopy. The z-average diameter of polymer particles is distributed in the range of 77.9–105.5 nm, which gives a better surface area for scavenging. The developed polymyrcene–photocatalytic system has exhibited an oxygen scavenging capacity of 1077 mL O2/g in 20 days at 25 °C. Similar values were obtained within 4 days when exposed to 45 °C. The reaction rate kinetics were analyzed by using collision theory, and the activation energy involved was estimated. The results proved that polymyrcene could be efficiently utilized as an oxygen absorber in active food packaging.

Brazil is the leading orange juice producer worldwide. Only about 50% of an orange is juice, so an enormous amount of waste is generated annually. In this context, studies involving alternatives for repurposing the remaining 50%, so it is not wasted or sent to landfill, are an issue of responsibility. In the present work, pectin is extracted to obtain a film‐forming solution (FFS). The extracted pectin is classified as high ester pectin since its degree of esterification (%DE) is higher than 50%. The FFS gives rise to transparent films with a low yellowing index. The addition of CaCl2 produces a crosslinked film with a 35% and 50% percentage increase in the contact angle and tensile strength, respectively. A FFS is proposed to be used without and with CaCl2 as edible packaging material. Herein, it is applied as an edible coating (EC), directly onto the peeled apple slices, or as an edible wrapping film. Both strategies aim to delay the browning of apples, evaluated by the browning index (BI). This result is important for the marketing of fresh‐cut fruits since the acceptance by consumers is strongly influenced by visual aspects.
