Pure and Co-Fermentation of Quinoa Seeds by Limosilactobacillus fermentum and Lacticaseibacillus rhamnosus: Bioactive Content, Antidiabetic and Antioxidant Activities

In this study, Limosilactobacillus fermentum PTCC 1638 and Lacticaseibacillus rhamnosus 1637 were used alone in combination to ferment quinoa seeds, the effect of fermentation (37 °C; 24 h) on pH, total phenols, tocopherols, vitamin C, antioxidant activity, enzymes inhibition (α-amylase α-glucosidase; antidiabetic effect) was investigated. The results showed that with increase time, bacterial population, increased, which greatest for co-culture L. compared pure culture each strain. Due tocopherol isomers (α, β, γ, δ), pH decreased, largest decrease related strains, followed by fermentum. study bacteria can have different effects physicochemical properties bioactive compounds seeds.
