In this study, vanillin (Van) crosslinked gelatin–polyvinyl alcohol (Gel−PVA) aerogels were prepared by vacuum freeze-drying method. The effects of different addition levels of Van on FTIR spectra, microstructures and physicochemical properties including water stability, mechanical properties, thermal stability and thermal insulation properties of aerogels were characterized, and antimicrobial activity of aerogels were validated. The results showed that Van exerted its crosslinking function through Schiff base bonding with Gel and hydrogen bonding with Gel and PVA. Although Van addition caused a slight decline in the thermal insulation performance and the obvious increase in pore diameter of aerogels, moderate Van crosslinking contributed to water stability, mechanical properties and thermal stability of aerogels. Besides, Van crosslinked Gel−PVA aerogel could effectively inhibit the growth of <em>E. coli</em> and <em>B. cinerea</em>. This suggests that the aerogel has promising applications in antimicrobial food packaging.</p></div>","PeriodicalId":12409,"journal":{"name":"Food Bioscience","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excess ROS can be eliminated, and its detrimental repercussions avoided by combining endogenous and exogenous antioxidants. A plant-based diet and dietary supplements are a major source of exogenous antioxidants; however, fungi, bacteria, lichens, insects, and algae (macroalgae and microalgae) are also deemed as potential sources for exogenous antioxidants. For example, algal biomass and extracts can be directly consumed or their purified metabolites can be used as antioxidants. Furthermore, some exogenous antioxidant molecules can be synthesized only by algae but not by other organisms. Antioxidant molecules derived from algae, include a variety of polysaccharides, pigments (carotenoids, phycobiliproteins etc), mycosporins-like amino acids, phytosterols, phenolic compounds (phenolic acids, bromophenols, phlorotannins, flavonoids etc), fatty acids, and alkaloids. They exhibit potent antioxidant activities confirmed by <em>in vitro</em> scavenging assays (DPPH, ABTS, hydroxyl, superoxide, hydrogen peroxide and nitric oxide radicals) and/or by reducing or chelating metal ions. In addition, algal-derived antioxidants have also been tested in <em>in vivo</em> models and have demonstrated high antioxidant activities achieved by upregulation of antioxidant enzymes (catalase, superoxide dismutase and glutathione peroxidase) and inhibition of lipid peroxidation.

Crude GP extracts (composed of stalks or a skin and seeds mixture–from red and white grape varieties) obtained using a modified solid-liquid extraction (water, ethanol, and acetone solvents) were evaluated for their antioxidant capacity (ABTS and DPPH assays), as well as the richness of phenolic compounds (total phenolic content-TPC, total flavonoid content-TFC, and HPLC-DAD assays). The GP extracts with the most favorable results were incorporated in a chitosan-alginate hydrogel (cross-linked with glutaraldehyde and calcium chloride), characterized (swelling, degradation, and release properties), and tested for its bioactivity (antioxidant and antimicrobial potential). TPC and TFC were higher in red GP extracts, as confirmed by the HPLC analysis, indicating a greater diversity of compounds in these extracts. Ethanolic white GP extracts (from skin-seeds mixture) showed the highest extraction yield and antioxidant activity. Their incorporation into the chitosan-alginate hydrogel improved its swelling and antimicrobial properties (total cytoplasmic membranes disruption and culturability reduction).

The biochemical profile of the extract was screened using high performance liquid chromatography -mass spectrometry (HPLC-MS) analysis. The total phenolic and flavonoid content was examined using the Folin-Ciocalteu assay and the aluminium trichloride assay, respectively. The antioxidant activity was evaluated through several tests, including 2,2-Diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), cupric reducing antioxidant capacity (CUPRAC), ferric reducing antioxidant power (FRAP), phosphomolybdenum (PBD), and metal chelating activity (MCA).
