Plantain flour noodles with wheat gluten and phosphate: technological properties and in vitro gut microbiota effects
Adding wheat gluten (≥17.5%) and compound phosphate improves the technological quality of plantain noodles and raises resistant starch content, with prebiotic effects observed only in an in vitro fermentation model.

What the study showed
The optimized formula increased bound water and disulfide bond formation, reducing breakage and cooking loss. In vitro digestibility for both protein and starch was reduced, with resistant components reaching 47.74% of total. In vitro fermentation indicated proliferation of short-chain fatty acid-producing bacteria and elevated propionate and butyrate levels.
How it was done
Product development study with formula optimization; assessment of textural properties, in vitro digestibility, and in vitro fermentation using human fecal microbiota.
Risk of bias
All microbiota and digestibility data are exclusively in vitro, with no human or animal validation. The abstract does not report the size or source of the fecal inoculum or fermentation duration.
What this study does NOT prove
The study does not prove that consuming these noodles benefits the gut microbiota or metabolic health in humans.
In clinical practice
No clinical recommendation is supported by this study. In vitro data cannot be extrapolated to human gut health outcomes.
Limitations
All microbiota and digestibility data are exclusively in vitro, with no human or animal validation. The abstract does not report the size or source of the fecal inoculum or fermentation duration.
