    Use of Encapsulated Pomegranate Seed Oil in Novel Coarse and Nanosized Materials for Improving the Storage Life of Strawberry
    (Elsevier Sci Ltd, 2024) Hassanein, Wael S.; Meral, Raciye; Ceylan, Zafer; Ahmed, Marwa M.; Yilmaz, Mustafa Tahsin
    Different-sized pomegranate seed oil-based emulsions (coarse (CsP) and nanoemulsions (NsP): 1246 and 325 nm) were successfully prepared. Strawberries treated with NsP and CsP showed a significant decrease (p < 0.05) in yeast-mold counts (TMY) by 1.80 log CFU g(-1), and mesophilic aerobic bacteria counts (TMAB) decreased (p < 0.05) by 0.91 log CFU g(-1), respectively. CsP- and NsP-treated strawberries had a TPC of 74.45 and 82.35 mg GAE kg(-1), respectively, while control samples had a TPC of 44.24 mg GAE kg(-1). The strawberries treated with NsP exhibited the highest antioxidant capacity with 179.44 mol TEAC g(-1). After treatment with a coarse emulsion, severity levels of A. niger and B. cinerea were 60 and 73 % while the nanoemulsion treatment significantly reduced severity levels to 55.3 and 56 %. The coarse and nanoemulsions may have potential use within the food industry owing to their antioxidant and antifungal properties as well as their ability to enhance strawberry quality and function.
