Information from the abstract
This study aimed to illustrate the effects of plant-based yogurts made from bio-fermentative green rice milk yogurt (GRMY), enhanced with Wolffia globosa powder (WGP) and infused with Thai green tea. Different formulations (F1 to F4) were analyzed to assess the impact of varying weight ratios of WGP, ranging from 0% to 15%. The goal was to improve nutritional values and bioactive components. The F4 formulation of plant-based yogurt demonstrated enhanced nutritional values, including higher levels of dietary fiber, starch, protein, and fat contents, which were 42.45, 26.55, 22.48, and 2.29% DW, respectively. It was increased by bioactive compounds such as total phenolic content (52.99 mg GAE/g), total flavonoid content (60.45 mg QUE/g), and β-carotene (1.81 mg/g). Additionally, the F4 formulation exhibited the highest antioxidants in terms of DPPH activity (5.48 mg TROE/g), ABTS activity (424.15 mg TROE/g), and FRAP reducing capacity (106.35 mg TROE/g) and antidiabetic activity of α–glucosidase inhibition in IC50 at 1.41 mg/mL. The yogurts were evaluated through metabolomic network analysis as a complex bioactive food system, wherein fermentation-derived metabolites synergistically interact with tea polyphenols, amino acids, phytosterols, and carotenoids. The prevailing metabolic profiles indicate an increase in antioxidant capacity, a reduction in inflammatory burden, enhanced glucose metabolism, alterations in gut microbiota, cardiovascular protection, and neuroprotective potential. These findings suggest that the product represents a promising plant-based functional food, offering numerous health benefits. This assertion is supported by a diverse metabolite network identified through UPLC–MS/MS metabolomic research.
