Aptamer-based electrochemical sensor detection is a promising method for rapidly and sensitively detecting heavy metals. However, aptamer configurations are easily affected by the environment and their stability needs to be improved. In this study, an ultra-sensitive electrochemical sensor was successfully constructed based on aptamer/dopamine molecularly imprinted polymer composite material, to explore the simultaneous detection of Cd(II) and Hg(II). Graphdiyne nanomaterial was used to increase the load of aptamer on the electrode surface. The aptamer of Cd(II) and Hg(II) was captured by AuNPs on a modified electrode through Au-S bonds. Dopamine was used as a functional monomer for self-polymerization to form an imprinted layer, stabilizing the aptamer conformation and enhancing its environmental tolerance. Under optimal conditions, the limits of detection (LOD) for Cd(II) and Hg(II) were 7.6 and 6.0 ng/mL, respectively. Six days of good stability in the sensor response were attained.

To overcome these challenges, this study aimed to prepare nanoemulsions of eugenol and neem oil using ultrasonication techniques and evaluating their antimicrobial efficacy, highlighting their potential for sustainable food preservation. The antimicrobial efficacy of these nanoemulsions was evaluated against four foodborne bacteria and spoilage fungi using well diffusion method. Nanoemulsions, formulated with oil concentrations of 5%–20%, exhibited particle sizes ranging from 135 to 373 d.nm for neem oil and 410 to 587 d.nm for eugenol, with polydispersity indices indicating variable size distribution (0.27–0.88 for neem oil and 0.13–0.60 for eugenol). Stability tests confirmed overall stability, although some eugenol-based nanoemulsions exhibited minor precipitation due to turbidity. Both neem oil and eugenol nanoemulsions displayed significant antimicrobial activity, with eugenol being more effective even at lower concentrations. NNE-20 showed the largest inhibition zones against <i>Bacillus subtilis</i> (17.83 mm), <i>Escherichia coli</i> (14.83 mm), and <i>Enterobacter aerogenes</i> (14.16 mm), while NNE-15 was most effective against <i>Staphylococcus aureus</i> (14 mm). Eugenol nanoemulsions exhibited superior antibacterial activity, achieving inhibition zones of 18–23.5 mm with higher eugenol concentrations. For fungi, neem oil nanoemulsions inhibited <i>Colletotrichum gloeosporioides, Rhizopus stolonifer</i> and <i>Aspergillus niger</i> (15–20 mm), while eugenol nanoemulsions outperformed neem oil, showing zones of 24–26 mm (<i>Aspergillus niger</i>) and 20–24 mm (<i>Saccharomyces cerevisiae</i>).

By using cutting-edge and environmentally friendly technology, <i>A. heterophyllus</i> peel can be used as a bioresource (raw material) to obtain a variety of high-value biocompounds, in line with the circular bioeconomy philosophy.

The findings of phytochemical screenings reported the presence of various bioactive compounds, such as alkaloids, steroids, glycosides, and tannins. Notably, the peel exhibited inhibitory effects against several bacterial strains, including <i>Alcaligenes faecalis</i>, <i>Staphylococcus aureus</i>, and <i>Escherichia coli</i> in the antimicrobial analysis. Additionally, Fourier-transform infrared spectroscopy analysis identified the presence of alcohols and phenols, while X-ray diffraction data displayed characteristic diffraction peaks at 20°–25°.

Moreover, mixed rice-wheat dough mainly underwent elastic deformation, and the addition of rice flour interfered with the formation of gluten network structure. Part of the bound water in the mixed flour dough migrates to free water, which showed that the continuity and uniformity of gluten network structure become worse by competing with wheat gluten for water absorption. When the addition of rice flour was 20%, the dough had the greatest viscoelasticity, micro-structure tensile property and texture, when the addition amount exceeded 30%, the toughness of the dough reduced, which made dough difficult to process.

Subsequently, utilizing PLA/MCNC as the base material and kaempferol as the active ingredient, a preliminary exploration into its potential as an active packaging material was carried out. When the addition amount of kaempferol was 10%, the DPPH and ABTS free radical scavenging ability of the nanofiber film reached more than 90%, demonstrating its application potential as an active packaging material. These results offer a promising strategy for the effective dispersion of CNC within PLA matrices, thereby expanding the potential applications of PLA in the field of active packaging.</p>","PeriodicalId":100544,"journal":{"name":"Food Bioengineering","volume":"4 1","pages":"28-38"},"PeriodicalIF":0.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fbe2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
