Food preservatives are commonly used to guarantee the safety and quality of food. Naturally-derived preservatives are preferred by the consumers as chemical preservatives are associated with adverse side effects. The application of naringenin as a food preservative is restricted due to its high volatility, albeit known for its good efficacy in inhibiting microbial growth on food. Thus, this study aimed to synthesis and characterise naringenin-grafted PVA (Na/PVA) nanoparticles as potential meat preservative. The nano-size of naringenin was characterised by transmission electron microscopy. Finally, the antibacterial efficiency of Na/PVA nanoparticles substance was evaluated on disc diffusion assay, broth microdilution assay and using fresh beef as food model. The naringenin nanoparticles appeared in globule and smooth structure, with an average size of less than 200 nm. In total, 11.08% of naringenin nanoparticles was successfully encapsulated into PVA nanoparticles. Based on Fourier transform infrared spectra, naringenin was successfully encapsulated into PVA nanoparticles. The release of naringenin from Na/PVA nanoparticles was slow and gradual, with an initial burst release effect observed. The property was ideal for application in food model. It gained a plateau at 48 h. The Na/PVA nanoparticles depicted its antibacterial efficiency on all the test foodborne bacteria, except E. coli. It was represented by the presence of inhibition zones, which were ranged from 10 mm to 14 mm. The activity was concentration-dependent, and a higher concentration of nanoparticles was needed to kill the test bacteria. The meat coated with Na/PVA nanoparticles displayed a 100% reduction in bacterial load, where no bacterial growth was detected at the sample throughout the incubation period. The coating of nanoparticles also improved the organoleptic property of fresh beef, by maintain the meat colour. The developed nanoparticles can be potentially used nano-preservative to maintain the microbiological quality of fresh beef.

“…Therefore, the presence of these compounds may contribute to the hypoglycemic effects demonstrated in the present study. Many compounds may be responsible for the antioxidant and anti-inflammatory activities of Baccharis gender, such as polyphenolics like phenolic acids, coumarins, and flavonoids (Figueiredo-Rinhel et al 2017;Bonin et al 2020). The results of this study suggest that the anti-inflammatory activity of B. dracunculifolia methanolic extract may be responsible for its hypoglycemic effect, which may be histologically observed by the absence of cellular necrosis and inter acinar fibroplasia, characterizing a healing process of tissue that favors the integrity of the organs.…”

“…B. dracunculifolia is a medicinal plant popularly utilized because of its anti-inflammatory, antiulcers properties and also because of its effects against hepatic diseases. From this plant, green propolis is obtained, which is a highly efficient product against microorganisms, and much valorized in the international market (Dallaqua and Damasceno 2011;Guimarães et al 2012;Bonin et al 2020). B. dracunculifolia antioxidant activities were studied by Hocayen (2016), who performed extractions with different solvents (ethanol, methanol, and acetone).…”

Background: Oxidative stress and the mild inflammatory process present in diabetes play a critical role in the pathogenesis of the disease and its comorbidities. This understanding has opened new avenues and targets for developing improved treatments since the risk factors associated with diabetes may be reduced through non-pharmacological interventions. In this sense, plant extracts could be efficient in preventing or assisting these pathological conditions treatment. Methods: Diabetes mellitus was induced in 24 rats, which were allocated in 4 groups: Control (CT), Control+Baccharis (CT-B), Diabetes (DB), and Diabetes+Baccharis (DB-B). For 28 days, the animals of CT-B and DB-B groups were treated, via gavage, with B. dracunculifolia extract at 50 mg.kg-1. Results: The DB group presented higher values than the DB-B group on parameters such as creatinine (26.42%), urea (31.42%), and triglycerides (60.80%). Creatinine and triglycerides values of DB-B group (0.39±0.01 e 75.0±8.4, receptively) were equivalent to the values of CT group (0.32±0.01 e 71.7±5.4) and of CT-B group (0.39±0.01, and 58.8±4.5). The treatment with B. dracunculifolia improved the levels of fasting glucose and response of glucose tolerance (32%), insulin (52,17%) and lipid peroxidation (liver 33.33%, kidney 38.77%) when compared to the DB group. Conclusions: The phenolic compounds and the anti-inflammatory activity of the extract of Baccharis dracunculifolia may be responsible for the hypoglycemic effect observed in the study.

This review presents a perspective on the research trends and solutions from recent years in the domain of antimicrobial packaging materials. The antibacterial, antifungal, and antioxidant activities can be induced by the main polymer used for packaging or by addition of various components from natural agents (bacteriocins, essential oils, natural extracts, etc.) to synthetic agents, both organic and inorganic (Ag, ZnO, TiO2 nanoparticles, synthetic antibiotics etc.). The general trend for the packaging evolution is from the inert and polluting plastic waste to the antimicrobial active, biodegradable or edible, biopolymer film packaging. Like in many domains this transition is an evolution rather than a revolution, and changes are coming in small steps. Changing the public perception and industry focus on the antimicrobial packaging solutions will enhance the shelf life and provide healthier food, thus diminishing the waste of agricultural resources, but will also reduce the plastic pollution generated by humankind as most new polymers used for packaging are from renewable sources and are biodegradable. Polysaccharides (like chitosan, cellulose and derivatives, starch etc.), lipids and proteins (from vegetal or animal origin), and some other specific biopolymers (like polylactic acid or polyvinyl alcohol) have been used as single component or in blends to obtain antimicrobial packaging materials. Where the package’s antimicrobial and antioxidant activities need a larger spectrum or a boost, certain active substances are embedded, encapsulated, coated, grafted into or onto the polymeric film. This review tries to cover the latest updates on the antimicrobial packaging, edible or not, using as support traditional and new polymers, with emphasis on natural compounds.
