Sustainable active packaging: cellulose-based vs LDPE films for extending jujube shelf life

Purpose The purpose of this study is to investigate the influence of temperature and active modified atmosphere packaging (AMAP) on the shelf life and quality retention of Umran jujube using cellulose-based biodegradable (CB) and low-density polyethylene (LDPE) films. Design/methodology/approach A comprehensive evaluation of jujube fruits’ physical properties was conducted. The mechanical, barrier, thermal, optical and biodegradability characteristics of CB and LDPE films were assessed. The experimental setup included five packaging conditions and five temperature levels, along with ambient storage as a control. Physico-chemical attributes such as antioxidant activity, ascorbic acid content, firmness, titratable acidity, total phenols, total soluble solids, gas composition, decay loss, sensory attributes and physiological weight loss were analyzed. Findings Jujube fruits stored at 9°C under AMAP conditions using both CB and LDPE films with an oxygen absorber exhibited an extended shelf life of up to 25 days while maintaining superior quality (p < 0.05). CB films demonstrated competitive mechanical strength, thermal stability and biodegradability, making them a viable alternative to conventional plastic packaging. Originality/value This study provides novel insights into the application of CB films in AMAP systems for jujube storage. The findings of this study support the use of CB films as a sustainable packaging alternative, addressing the need for environmentally friendly solutions while ensuring optimal fruit quality and shelf-life extension.
