Published: Feb. 12, 2022

Even though food by-products have many negative financial and environmental impacts, they contain a considerable quantity of precious bioactive compounds such as polyphenols. The recovery these from wastes could diminish their adverse effects in different aspects. For doing this, various nonthermal conventional methods are used. Since extraction may cause plenty problems, due to heat production extreme need for energy solvent, novel technologies microwave, ultrasound, cold plasma, pulsed electric field, pressurized liquid, ohmic heating technology been regarded alternatives assisting the process. This paper highlights competence mild polyphenols by-products, effect on polyphenol oxidase, application recovered industry.

Viburnum opulus Fruit Phenolic Compounds as Cytoprotective Agents Able to Decrease Free Fatty Acids and Glucose Uptake by Caco-2 Cells

Antioxidants, Journal Year: 2019, Volume and Issue: 8(8), P. 262 - 262

Published: Aug. 1, 2019

In recent years, there has been increasing interest in studying food-originated phytocompounds with beneficial influences for humans. Amongst the most active natural substances are polyphenols, which high content identified Viburnum opulus berry, and unused Western Europe. Due to its strong antioxidant activity we explored potential of V. as a preventive agent against diet-related chronic diseases, such obesity type 2 diabetes. Among causes these ailments is oxidative stress, well impaired glucose free fatty acids (FFA) uptake. Thus, purpose this study was determine biological phenolic extracts cytoprotective agents able decrease induced lower lipid accumulation attenuate FFA uptake by Caco-2 cells via GLUT2 CD36/FAT transporters. To source biologically compounds, obtained four compounds crude juice, phenolics isolated from juice two preparations different extraction fruit pomace. studied extracts, rich fraction revealed strongest glucose, droplets without affecting their viability (IC0 50 μg/mL). Observed attenuation followed gene expression, influence on PPARα levels. We suspect that were modulate cellular membrane dynamic, although hypothesis requires further, more detailed studies. Extracts chemo-preventive stress chemically tert-butylhydroperoxide (t-BOOH), DNA damage through induction repair after cell exposition methylnitronitrosoguanidine (MNNG) H2O2.

Published: Jan. 14, 2021

Exploring the chemical composition and biological activity of different fruit varieties is essential for valorization their health claims. The current study focuses on a detailed comparative analysis three early- two mid-ripening peach varieties: “Filina” (peach), “July Lady” “Laskava” “Gergana” (nectarine), “Ufo 4” (flat peach). They were characterized in terms nutrients such as carbohydrates (sugars dietary fibers), amino acid content, lipids well mineral fat-soluble vitamins, carotenoids, chlorophyll. Polyphenolic compounds related antioxidant also assessed. methanolic extract peel seems to be richer studied biologically active substances compared fleshy part fruit. Anthocyanins most abundant extracts (6624.8 ± 404.9 7133.6 388.8 µg cyanidin-3-glucoside/100 g fw, resp.). total phenol content samples varied from 34.11 0.54 157.97 0.67 mg gallic equivalents (GAE)/100 fw. possessed highest activity.
