This study aimed to evaluate the optimal nitrogen source for the production of antioxidant exopolysaccharides (EPSs) by KW8 using cassava pulp carbon source. Various nitrogen sources were initially screened, and yeast extract was identified as the most effective. Further optimization was conducted using Response Surface Methodology (RSM) with a Central Composite Design (CCD) to assess the influence of key parameters, including pH, inoculum size, carbon-to-nitrogen (C/N) ratio, and agitation speed on EPS production.

Northeastern Thai ethnic foods are celebrated for their health benefits yet remain largely underexplored. This study assessed the antioxidant and cytotoxic properties of two ready-to-eat pastes-Jaew Hon (JH) and Gang Om (GO)-produced using laboratory (LAB) and industrial original equipment manufacturer (OEM) methods. Evaluations were conducted using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), total phenolic content (TPC), and total flavonoid content (TFC) assays alongside the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cytotoxicity.
