Investigation of the antioxidant activity of Crimean polyphenol concentrates done by bio-luminescence method
To analyze the biological activity of polyphenol concentrates, the study used bio-luminescence method based on measurement of luminescence of the test bacteria. The study analyzed samples of grape food concentrates: “Enoant”, “grape polyphenols extract” (GPE) and “Fenokor”. For the bio-luminescence study, test bacteria Photobacterium leiognathi Sh1 were used. Series of experiments included quantitative bio-testing of acute and chronic toxicity of samples on the glow of test bacteria. The in vitro model showed that all polyphenol concentrates dose-dependently inhibited the luminescence of test bacteria, which correlates with the antioxidant activity of wine materials and attests to their biological efficiency.
