Putrescine and cadaverine are among the most common biogenic amines (BA) in foods, but it is advisable that their accumulation be avoided. Present knowledge about their toxicity is, however, limited; further research is needed if qualitative and quantitative risk assessments for foods are to be conducted. The present work describes a real-time analysis of the cytotoxicity of putrescine and cadaverine on intestinal cell cultures. Both BA were cytotoxic at concentrations found in BA-rich foods, although the cytotoxicity threshold for cadaverine was twice that of putrescine. Their mode of cytotoxic action was similar, with both BA causing cell necrosis; they did not induce apoptosis. The present results may help in establishing legal limits for both putrescine and cadaverine in food.

Microneedle (MN) sensors have great promise for food safety detection, but the rapid preparation of MNs for surface-enhanced Raman scattering (SERS) sensors with tunable and homogeneous nanoparticles remains a great challenge. To address this, a SERS sensor of gold nanoparticles@polydopamine@poly(methyl methacrylate) MN (AuNPs@PDA@PMMA-MN) was developed. The extended-Derjaguin-Landau-Verwey-Overbeek theory was applied to calculate the interaction energy between AuNPs and PDA.

Given the widespread industrial and domestic use of probiotic blends based on combinations of lactic acid bacteria (LAB) and yeasts to produce fermented foods or beverages that are supposed to provide health benefits, this study aimed to generate knowledge and concepts on biologically relevant activities, metabolism and metabolic interactions in yeast/LAB communities. For this, the postbiotic capabilities of three probiotic candidates, including two lactic acid bacteria (i.e.

Article Synopsis
- The World Health Organization aims to reduce salt intake by 30% by 2025, prompting this study to explore the effects of replacing 33% of NaCl with KCl and microencapsulated spices in a dry-cured meat sausage.
- The formulations tested (Control, F1, F2, F3) maintained microbial safety, showing no growth of harmful bacteria while lactic acid bacteria remained stable.
- Consumer preference indicated that F1, with the adjusted salt levels, was favored as the ideal saltiness for potential market launch, confirming that significant NaCl replacement can be done without compromising taste or safety.

The application of low-salt fish sauce is limited by its tendency to spoil easily and inadequate flavor generation. Herein, a salt-tolerant Tetragenococcus halophilus 2MH-3 strain with strong abilities of enzyme production and biogenic amine degradation was utilized as a starter for the production of low-salt fish sauce. Bacterial community analysis revealed discrepancies in microbiota between low-salt fish sauces fermented with (Th group) or without 2MH-3 (LF group).
