Nanotechnology plays a crucial role in food preservation, offering innovative solutions for monitoring and enabling the creation of packaging with unique functional properties. The nanomaterials used can extend shelf life foods, enhance safety, keep consumers informed about contamination or spoilage, repair damage, even release preservatives to prolong durability items. Therefore, this review aims provide an overview diverse applications nanotechnology packaging, highlighting its key...
Prickly pear consumption is increasing across the world due to its rich variety of nutrients and bioactive compounds. Yet, it a seasonal highly perishable fruit, application edible coatings emerges as an alternative extend shelf life. In this work, effects alginate, starch, chitosan, pectin on physicochemical, bioactive, microbiological, textural properties two prickly varieties (orange red), kept under refrigeration (5 ± 2 °C) were evaluated for 6 weeks. Coatings proved be helpful in...
The advances on the development of novel materials capable to enhance shelf life food products may contribute reduce current worldwide waste problem. Zinc oxide nanoparticles (ZnO NPs) are considered GRAS (Generally Recognized as Safe) by Food and Drug Administration (FDA) due their good antimicrobial properties suitable be applied active compounds in packaging. ZnO NPs were synthesized tested bionanocomposites through an eco-friendlier route using apple peel wastes. This work aimed develop...
Active packaging incorporated with natural extracts is a promising technology to extend shelf life of perishable food. Therefore, this study aimed produce bionanocomposite based on chitosan reinforced sodium montmorillonite (MMT) and ginger essential oil (GEO). In vitro activity was assessed through migration assay antimicrobial against foodborne bacteria. Phenolic compounds were diffused within 48 h contact, retained some their antioxidant activity. Films demonstrated both Gram-positive...
Novel bionanocomposite films of chitosan/montmorillonite (CS/MMT) activated with ginger essential oil (GEO) were produced and characterized in terms their physical morphological properties. The homogenization process led to a good interaction between the chitosan nanoparticles, however exfoliation was diminished when GEO incorporated. Film glass transition temperature did not statistically change incorporation either MMT or GEO, value slightly reduced, representing relaxation polymer chain...
Algae and seaweeds are used in cookery since the beginnings of human civilization, particularly several Asian cultures. Phenolic compounds secondary metabolites produced by aquatic terrestrial plants for their natural defense against external stimuli, which possess powerful antimicrobial antioxidant properties that can be very important food industry. The main objective this study was to develop a whey protein concentrate active coating, incorporated with Fucus vesiculosus extract order...
Traditional food packaging systems help reduce wastage, but they also produce environmental impacts when not properly disposed of. Bio-based polymers are a promising solution to overcome these impacts, have poor barrier and mechanical properties. This work evaluates two strategies improve properties in pectin films: the incorporation of cellulose nanocrystals (CNC) or sodium montmorillonite (MMT) nanoparticles, an additional layer chitosan (i.e., bilayer film). The bionanocomposites films...
