“…The addition of plasticizers to proteins can lead to changes in their three-dimensional structure, where plasticizers enter between protein molecular chains and join proteins through physical interactions and chemical reactions, resulting in increased ductility, flexibility, and elasticity and decreased mechanical properties, cohesion, and stiffness (Ananey-Obiri et al, 2018). Currently, plasticizers, such as those made from soy protein isolate (Zhu et al, 2023), corn protein (Baloyi et al, 2023), milk protein (Stefano et al, 2023), and whey protein isolate (Mariana et al, 2022), have been used in protein-based packaging films, and good results have been obtained. Water is the most used best-performing plasticizer in the preparation of protein films.…”

Biopolymer packaging materials are an emerging trend in food packaging due to their degradability, nontoxicity, low cost, and low environmental stress; moreover, some properties of biopolymer packaging are better than those of traditional packaging. Proteins are a type of natural biopolymer packaging film matrix, and enhancing the packaging properties of proteins has been a focus of research. Preparing protein‐active packaging films by adding natural active substances with antimicrobial and antioxidant properties and nanoparticles to protein‐based films to provide more significant antimicrobial, antioxidant, and UV‐blocking effects is essential in food packaging and demonstrates the potential of using proteins in active food packaging applications. In recent years, the origin of natural actives, their mechanism of action, and their release from active packaging films have attracted much attention. In this review, we provide a comprehensive overview of protein film matrices for active packaging, natural antimicrobial agents, and natural antioxidants and discuss the potential of such active films in the packaging field. The sources of natural antimicrobial active substances and natural antioxidant active substances in packaging materials, their mechanisms of action, and their effects after being used to modify protein active films are summarized. The biorelease functions of protein active films with antimicrobial and antioxidant effects and their applications for various types of food are highlighted to understand the current effects of protein active films in food packaging.

Nanomaterials, due to their unique structural and functional features, are widely investigated for potential applications in a wide range of industrial sectors. In this context, protein-based nanoparticles, given proteins’ abundance, non-toxicity, and stability, offer a promising and sustainable methodology for encapsulation and protection, and can be used in engineered nanocarriers that are capable of releasing active compounds on demand. Zein is a plant-based protein extracted from corn, and it is biocompatible, biodegradable, and amphiphilic. Several approaches and technologies are currently involved in zein-based nanoparticle preparation, such as antisolvent precipitation, spray drying, supercritical processes, coacervation, and emulsion procedures. Thanks to their peculiar characteristics, zein-based nanoparticles are widely used as nanocarriers of active compounds in targeted application fields such as drug delivery, bioimaging, or soft tissue engineering, as reported by others. The main goal of this review is to investigate the use of zein-based nanocarriers for different advanced applications including food/food packaging, cosmetics, and agriculture, which are attracting researchers’ efforts, and to exploit the future potential development of zein NPs in the field of cultural heritage, which is still relatively unexplored. Moreover, the presented overview focuses on several preparation methods (i.e., antisolvent processes, spry drying), correlating the different analyzed methodologies to NPs’ structural and functional properties and their capability to act as carriers of bioactive compounds, both to preserve their activity and to tune their release in specific working conditions.

Microwave intermittent drying was carried out on newly harvested corn kernels to study the effects of different microwave intermittent powers (900 W, 1800 W, 2700 W, and 3600 W) on the structural and functional properties of zein in corn kernels. The results showed that microwave drying could increase the thermal stability of zein in corn kernels. The solubility, emulsification activity index, and surface hydrophobicity increased under 1800 W drying power, which was due to the unfolding of the molecular structure caused by the increase in the content of irregular structure and the decrease in the value of particle size. At a drying power of 2700 W, there was a significant increase in grain size values and β-sheet structure. This proves that at this time, the corn proteins in the kernels were subjected to the thermal effect generated by the higher microwave power, which simultaneously caused cross-linking and aggregation within the proteins to form molecular aggregates. The solubility, surface hydrophobicity, and other functional properties were reduced, while the emulsification stability was enhanced by the aggregates. The results of the study can provide a reference for the in-depth study of intermittent corn microwave drying on a wide range of applications of zein in corn kernels.
