“…Nanocellulose is inert with respect to these functions, but is an excellent support for substances that may play an active or intelligent role in the food packaging system. Combinations of nanocellulose with different active agents have been reported, as for examples: flavonoid silymarin (SMN) [ 86 ], ferulic acid and derivatives [ 97 ], tannins [ 98 ], titanium dioxide (TiO 2 ) [ 99 ], silver [ 100 ], lactoferrin [ 101 ], and sorbic acid [ 102 ].…”

“…Arabinoxylans-based nanocomposite films containing 50% nanofibrillated cellulose, prepared by solvent casting, were functionalized with ferulic acid and feruloylated arabinoxylo-oligosaccharides, showing antioxidant activity up to 90% in the 2,2-diphenyl-1-picrylhydrazyl hydrate assay. The films also showed bactericidal effects, with 3–log CFU mL −1 reduction against Staphylococcus aureus , bacteriostatic activity against Escherichia coli and antifungal activity towards the polymorphic fungus Candida albicans with 1.1–log CFU mL −1 reduction [ 97 ].…”

The food industry is increasingly demanding advanced and eco-friendly sustainable packaging materials with improved physical, mechanical and barrier properties. The currently used materials are synthetic and non-degradable, therefore raising environmental concerns. Consequently, research efforts have been made in recent years towards the development of bio-based sustainable packaging materials. In this review, the potential of nanocelluloses as nanofillers or as coatings for the development of bio-based nanocomposites is discussed, namely: (i) the physico-chemical interaction of nanocellulose with the adjacent polymeric phase, (ii) the effect of nanocellulose modification/functionalization on the final properties of the composites, (iii) the production methods for such composites, and (iv) the effect of nanocellulose on the overall migration, toxicity, and the potential risk to human health. Lastly, the technology readiness level of nanocellulose and nanocellulose based composites for the market of food packaging is discussed.

Introduction. Brewery mash, or brewer’s spent grain (BSG), is a by-product of brewing industry. It is known to contain valuable biologically active substances. However, their extraction is complicated by the presence of various polymers. The research featured various physicochemical methods for obtaining valuable biological compounds from brewery waste. The new method modified complex non-starch polysaccharides, lignin, arabinoxylans, and other high-molecular compounds associated with phenolic compounds. The research objective was to solve the problem of recycling industrial by-products that accumulate in large quantities and require expensive processing or disposal. The paper introduces new technological approaches for deep processing of BSG as a source of secondary raw materials in order to obtain extracts fortified with polyphenolic compounds. Study objects and methods. The research featured BSG from malt subjected to treatment with ECA-activated water (catholyte with pH 9.6 ± 0.1), followed by enzymatic hydrolysis of cellulolytic enzyme preparations and extraction with a polar solvent of the resulting free polyphenolic substances. The experiments were based on standard methods for assessing the content of various biologically active substances. Results and discussion. A 70% water-ethanol solution proved to be optimal at the BSG:extractant ratio of 2:1, process temperature = 50 ± 2°C, and extraction time = 60 ± 5 min. Under the same conditions, 70 %vol. of beer distillate made it possible to extract phenolic acids, flavonoid rutin, irreplaceable and nonessential amino acids, and non-starch polysaccharide β-glucan from the BSG matrix. The BSG treatment with 1M NaOH solution delivered viscous hydrolysates fortified with flavonoids rutin and quercetin, which did not happen when acid hydrolysis was used. The combined use of ECA-treated water (catholyte with pH 9.6 ± 0.1) for 24 ± 0.05 h, combined with biocatalysis with the enzyme preparation Viskoflo MG for 2 ± 0.05 h, made it possible to obtain BSG extracts with a high content of phenolic acids and aldehydes, as well as flavonoid rutin. Conclusion. The study revealed the mechanism of hydrolytic decomposition of BSG non-starch polysaccharides, considering the compounds contained in the extracts. The BSG hydrolysates fortified with various phenolic compounds can be used in various food technologies, e.g., in fermented drinks.

“…Microcrystalline cellulose (MCC) and nanofibrillated cellulose (NFC) have also used been for similar purposes [ 44 , 45 ]. Nanocellulose-based films are usually combined with other biopolymers, as chitosan and PHA, or plasticizers (e.g., glycerol, sorbitol, methoxypolyethylene glycol (MPEG) [ 46 ]) to improve or modify their physicochemical properties and extend their application range [ 47 , 48 , 49 , 50 ]. These biocomposites have shown excellent mechanical and oxygen barrier properties; however, their performances rapidly decline in the presence of moisture [ 49 , 50 , 51 , 52 ].…”

This review aims to showcase the current use of graphene derivatives, graphene-based nanomaterials in particular, in biopolymer-based composites for food packaging applications. A brief introduction regarding the valuable attributes of available and emergent bioplastic materials is made so that their contributions to the packaging field can be understood. Furthermore, their drawbacks are also disclosed to highlight the benefits that graphene derivatives can bring to bio-based formulations, from physicochemical to mechanical, barrier, and functional properties as antioxidant activity or electrical conductivity. The reported improvements in biopolymer-based composites carried out by graphene derivatives in the last three years are discussed, pointing to their potential for innovative food packaging applications such as electrically conductive food packaging.
