“…[81] Cerisuelo et al (2014) coated EVOH29 nanocomposites containing 2 wt% bentonite on PP and PET, but found that this did not significantly improve the barrier properties as opposed to the PP and PET samples coated with regular EVOH29. [82] Sadeghi and Shahedi (2016) developed an EVOH/ chitosan polymer mixture film containing nano-ZnO. The incorporation led to a decrease in both P O 2 and P H 2 O when the ZnO content was increased by filling pores in the film matrix and the creation of a tortuous path.…”

The gas barrier properties of ethylene vinyl alcohol copolymer (EVOH) against oxygen, carbon dioxide and water vapor have been widely investigated in relation to different material characteristics, environmental conditions and new processing technologies. Recently, EVOH is gaining more attention as a barrier material against other gases and organic substances such as aromas, flavors, fuels, chemicals (e.g., BTEX), and as a functional barrier, e.g., to avoid mineral oil migration. This review contains an update on permeability data of EVOH emphasizing its potential as a barrier material for new and versatile applications in food and pharmaceutical packaging, agriculture, construction, automotive, etc.

“…The low concentration of O 2 has no impact on mycotoxin formation in raw materials, while high levels of CO 2 do not guarantee elimination of spoilage. According to other studies, the use of EVOH film possesses protective properties against water vapor and gas permeability [29][30][31]. The asparaguses respiration changes during the first 2 days of storage, which were determined as a crucial factor affecting raw material shelf-life.…”

Application of MAP and ethylene–vinyl alcohol copolymer (EVOH) to extend the shelf-life of green and white asparagus (Asparagus officinalis L.) spears

In this study, ethylene vinyl alcohol copolymer (EVOH) and polypropylene/polyethylene (PP/PE) films combined with MAP packaging were developed to enhance the shelf-life of green and white asparagus spears. The scope of the research included measurements of weight loss, pH, acidity, color, texture, and sensory analysis as indicators of green and white asparagus spear quality for up to 17 days of storage at 2 and 10 °C. The application of modified atmosphere packaging combined with EVOH-based packaging material and refrigeration at 2 °C promoted a reduction in asparagus weight loss, preventing changes in color and texture as well as sensory quality, thereby extending the shelf-life of the asparagus. According to the obtained results, it was possible to maintain good quality of green and white asparagus for up to 17 and 10 days, respectively, when packed in MAP using EVOH-based packaging stored at 2 °C. Asparagus stored in packaging with PP/PE film showed lower quality during storage at 2 and 10 °C. These results suggest that EVOH films are potential candidates for advanced packaging materials for the asparagus packaging application.

“…Film thickness was measured with a C112-B Mitutoyo micrometer with a precision of 1 µm. Oxygen permeability at 90% RH was determined with an Oxtran 2/21 ML (Mocon, Minneapolis) with the procedure reported elsewhere (Cerisuelo, Gavara, & Hernandez-Munoz, 2014), using a 20 mm 2 test area.…”

The aim of this work was the industrial development of an antifungal film containing garlic extract and bread aroma to be applied as active packaging for preservative-free sliced pan loaf. The material consisted of LDPE coated with ethylene vinyl alcohol copolymer. First the coating formulation was optimized to be suitable for flexographic equipment. A 1 µm coating of EVOH containing the agents was applied onto the LDPE film. Garlic extract release provides the antimicrobial capacity while bread aroma masks the inappropriate garlic aroma. The optimized formulation contained 8% of garlic extract and 8% of bread aroma. Bags were prepared and used to pack sliced pan loaves. Mould development was delayed from 6 to 12 days by use of the active bag. Sensory and textural characterization of the food also revealed that the bread maintained its characteristics, and sensory panellists considered the product acceptable and with good purchase intention.
