A liver lobule microtissue biosensor, newly developed using 3D bio-printing, is detailed in this paper for the rapid assessment of aflatoxin B1 (AFB1). HepG2 cells, methylacylated hyaluronic acid (HAMA) hydrogel, and carbon nanotubes are the components utilized in the fabrication of liver lobule models. High-throughput and standardized preparation via 3D bio-printing is employed to simulate organ morphology and to induce functional organization. After the application of electrochemical rapid detection, a 3D bio-printed liver lobule microtissue was immobilized on a screen-printed electrode for the purpose of mycotoxin detection via differential pulse voltammetry (DPV). The DPV response's magnitude is directly proportional to the AFB1 concentration, varying from 0.01 to 35 g/mL. Concentrations from 0.01 to 15 grams per milliliter are linearly detectable, and the calculated lowest limit of detection is 0.0039 grams per milliliter. This research, consequently, crafts a novel mycotoxin detection technique, capitalizing on the steadfast and reproducible nature of 3D printing technology. This technology shows broad promise for assessing and identifying foodborne hazards.

A key aim of this investigation was to assess the role of Levilactobacillus brevis in shaping the fermentation pace and flavor attributes of radish paocai. Radish paocai produced via inoculated fermentation, using Levilactobacillus brevis PL6-1 as a starter, demonstrated a considerably more rapid conversion of sugar to acid compared to spontaneous fermentation, thus accelerating the fermentation duration. The IF's texture, encompassing hardness, chewiness, and springiness, surpassed that of the SF, and the IF paocai exhibited a higher L-value in its colorimetric profile. As a starter culture, L. brevis PL6-1 can potentially increase the ultimate concentrations of the metabolites mannitol (543 mg/g), lactic acid (54344 mg/100 g), and acetic acid (8779 mg/100 g). Fifteen volatile organic compounds, or VOCs, were recognized as key odor-active components in radish paocai, with eight distinct VOCs flagged as potential markers. Utilizing L. brevis PL6-1 can lead to improved levels of 18-cineole, 1-hexanol, hexanoic acid, 2-methoxy-4-vinylphenol, and eugenol, resulting in a radish paocai that possesses a delightful floral, sweet, and sour aroma, and mitigating the objectionable odors associated with garlic, onion, and compounds like erucin, diallyl disulfide, and allyl trisulfide. Sensory analysis results for IF paocai indicated superior attributes across appearance, flavor, mouthfeel, and overall consumer acceptance when compared to the SF group. In conclusion, L. brevis PL6-1 has the potential to act as a beneficial starter culture, improving the flavor and sensory perception in radish paocai fermentation.

The monocotyledon Smilax brasiliensis Sprengel, a plant of the Smilacaceae family, hails from the Brazilian Cerrado and is popularly recognized as salsaparrilha or japecanga. The stems' ethanol extract (EE) and hexane (HEXF), dichloromethane (DCMF), ethyl acetate (ACF), and hydroethanol (HEF) fractions were isolated in this study. The determination of chemical composition, quantification of phenolic compounds and flavonoids, and evaluation of antioxidant potential and cytotoxic effect on Artemia salina were undertaken. Employing gas chromatography-mass spectrometry (GC-MS), fatty acid esters, hydrocarbons, and phytosterols were identified within the HEXF sample. Using liquid chromatography coupled with diode array detection and mass spectrometry (LC-DAD-MS), the samples of EE, DCMF, ACF, and HEF were characterized. Significant findings included the presence of glycosylated flavonoids, such as rutin, 3-O-galactopyranosyl quercetin, 3-O-glucopyranosyl quercetin, O-deoxyhexosyl-hexosyl quercetin, O-deoxyhexosyl-hexosyl kaempferol, O-deoxyhexosyl-hexosyl O-methyl quercetin, and additional compounds, along with non-glycosylated quercetin, phenylpropanoids including 3-O-E-caffeoyl quinic acid, 5-O-E-caffeoyl quinic acid, O-caffeoyl shikimic acid, and others, neolignan, steroidal saponin (dioscin), and N-feruloyltyramine. Across the samples of EE, DCMF, and ACF, phenolic compound totals were exceptionally high (11299, 17571, and 52402 g of GAE/mg, respectively), while ACF and DCMF also showed high concentrations of flavonoids (5008 and 3149 g of QE/mg, respectively). The antioxidant potential of the EE, DCMF, ACF, and HEF was remarkably high, as demonstrated by DPPH (IC50 171 – 3283 g/mL) and FRAP (IC50 063 – 671 g/mL) assays. A noteworthy 60% cytotoxic action on *A. salina* was recorded for DCMF, possessing an LC50 of 85617 g/mL. Through this study, further insight into S. brasiliensis phytochemicals is gained, as these compounds are newly identified from the stem tissues of this species. Stems of S. brasiliensis were shown to harbor a wealth of polyphenol compounds, presenting a considerable antioxidant potential without causing any toxicity. Subsequently, the fractions and extracts from *S. brasiliensis* stems are potentially useful as food supplements or natural antioxidants in the culinary realm.

The response of pathogenic bacteria to other external stressors can be contingent on low temperatures. A low-temperature investigation into the tolerance of L. monocytogenes and E. coli O157H7 to acidic electrolyzed water (AEW) was the focus of this study. The AEW treatment inflicted damage upon the pathogenic bacteria's cell membranes, resulting in protein leakage and subsequent DNA damage. Pathogenic bacteria cultivated at 37°C (in pure culture) demonstrated more cellular damage compared to L. monocytogenes and E. coli O157H7 cells cultured at reduced temperatures, which exhibited lower damage and a higher survival rate upon exposure to AEW. In summary, bacteria cultivated at 4°C or 10°C were less sensitive to AEW treatment compared to those grown at the 37°C temperature. Experimental treatment of inoculated salmon with AEW, specifically targeting the pathogenic bacteria, verified the observed phenomenon. RNA-seq, a transcriptomic sequencing approach, was used to discover the underlying mechanisms enabling L. monocytogenes to tolerate AEW exposure at low temperatures. Transcriptomic analysis revealed the involvement of cold shock protein expression, DNA-templated transcription regulation, ribosome pathway activity, phosphotransferase system (PTS) function, bacterial chemotaxis mechanisms, SOS response activation, and DNA repair processes in Listeria monocytogenes' resistance to AEW. We proposed that modulating the expression of cold shock protein CspD, either directly or through the modulation of Crp/Fnr family transcriptional regulators or the enhancement of cAMP levels by regulating PTS pathways, may reduce the resistance of L. monocytogenes cultivated at 4°C to AEW. Our research investigates and strives to resolve the problem of decreased bacteriostatic activity prevalent in cold storage environments.
