    Recent Developments Shaping the Future of Antimicrobial Edible Food Packaging: a Review
    (Wiley, 2024) Yemenicioglu, Ahmet
    This article aimed at reviewing recent developments shaping the future of antimicrobial edible food packaging. The main issues discussed in the article are (i) factors (e.g. waste valorisation, sustainability, health and environmental concerns, religious concerns, etc.) causing emerging of alternative hydrocolloids extracted from farming/processing wastes of plants, animals, fungi, insects, snails, etc. as antimicrobial edible packaging material; (ii) emerging methods of manufacturing antimicrobial packaging (e.g. extruded and co-extruded antimicrobial casings, antimicrobial electrospun mats, and electrosprayed films, coatings and particles); (iii) emerging concepts in using natural antimicrobials in edible packaging such as using narrow- or broad-spectrum antimicrobials, synergetic mixtures, and controlled release strategies based on nanoencapsulation (e.g. Pickering emulsions, nanoemulsions, inclusion complexes, solid lipid nanoparticles and nanostructured lipid carriers). This review helps discovering the future of active edible packaging that is expected to play a central role in improving food safety and quality, human health and environmentally friendly practices.

    Incorporation of Organic Acids Turns Classically Brittle Zein Films Into Flexible Antimicrobial Packaging Materials
    (Wiley, 2021) Sözbilen, Gözde Seval; Çavdaroğlu, Elif; Yemenicioğlu, Ahmet
    This study aimed to turn classically brittle zein films into flexible antimicrobial ones by the use of lactic (LA), malic (MA) and tartaric acids (TA). The most effective plasticizer was LA (400% elongation at break [EB] at 4%), while MA (189% EB at 4.5%) and TA (68% EB at 5%) showed moderate and limited plasticizing effects, respectively. The LA- and MA-loaded films maintained their flexibility during 30-day storage at 4 degrees C or 25 degrees C. Fourier transform infrared (FTIR) analysis suggested that the plasticization of LA and MA could be related to secondary structural changes in zein such as increased alpha-helix and random coils (mainly by MA) and spaced/modified intermolecular (only by LA) and intramolecular (mainly by MA) beta-sheets. Atomic force and scanning electron microscopy showed that LA and MA gave more homogenous and smoother films than TA. Films with LA showed the highest water vapour permeability followed by those of control, MA- and TA-loaded films. Films with 3%-4% LA or MA formed clear zones on Listeria innocua and Klebsiella pneumonia, but only films with LA formed clear zones on Escherichia coli. All OA-loaded films gave unclear zones on Staphylococcus aureus in disc-diffusion tests, but this bacterium was inactivated rapidly in antimicrobial tests based on surface inoculation tests. LA is the best OA to develop flexible antimicrobial films from zein, an industrial by-product that films could not have been utilized as a widespread packaging material due to their brittleness.
