The antimicrobial and antioxidant properties of garagurt: Traditional Cornelian cherry (Cornus mas) marmalade

Abstract

The traditional Cornelian cherry marmalade, named as 'Garagurt' , is usually consumed for nutritional purposes and health benefits. The objective of this study was to determine the antimicrobial and antioxidant activities of Cornelian cherry marmalade. Antioxidant activities of the sample as determined by ABTS, cupric ion-reducing antioxidant capacity (CUPRAC) and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assays were 8,428 ± 1,206 mg TE/100 g, 1,599 ± 41.4 mg TE/100 g and 773 ± 206 mg TE/100 g respectively. The antimicrobial activity of the sample was determined by the disc diffusion method in minimum inhibitory concentration (MIC) against Listeria monocytogenes, Bacillus cereus, Staphylococcus aureus, Escherichia coli, Escherichia coli O157:H7, Salmonella typhimurium, Pseudomonas fluorescens and Yersinia enterocolitica. The MIC value of garagurt (0.66 mg phenol compound/g) was ≥256 mg/mL for L. monocytogenes, S. aureus, Y. enterocolitica, E. coli and P. fluorescens when gentamicin (10 µg) was used as positive control. Total phenolic content (TPC), which provides antimicrobial and antioxidant activities, was determined as 195 ± 6.35 mg GAE/100 g in aqueous methanolic extract of garagurt. This product in different forms could be used for its antimicrobial effect to increase the shelf life of different foods.

An Investigation of the Interaction between Bovine Serum Albumin-Conjugated Silver Nanoparticles and the Hydrogel in Hydrogel Nanocomposites

“…Our results are consistent with Sarvaş et al findings. 57 Gentamicin is able to gain entrance into the Gram-positive cell by binding to the anionic sites on the Gram-positive cell wall via teichoic acids and phospholipids. 58 More detailed studies are needed to validate our findings in terms of silver nanoparticles’ improved potency toward Gram-positive bacteria and gentamicin’s improved potency toward Gram-negative bacteria.…”

Potential Application of Cornelian Cherry Extract on Broiler Chickens: Growth, Expression of Antioxidant Biomarker and Glucose Transport Genes, and Oxidative Stability of Frozen Meat

“…The antimicrobial properties of polyphenols are of primary significance and inhibit biofilm formation in the gut by suppressing harmful bacteria [ 63 ]. In vitro testing of the antimicrobial activity of cornelian cherry extract demonstrated its inhibitory effects against Staphylococcus aureus and Escherichia coli [ 64 ]. Caffeic acid, present in CCE, has been described as a potential inhibitor of the growth of E. coli and Clostridium [ 65 ].…”

Antimicrobial potential of kombucha against foodborne pathogens

“…Recently, in order to reduce the heavy burden of foodborne diseases, natural antiseptic strategies have been increasingly developed to control foodborne pathogens (Ghazy et al, 2021;Kim et al, 2021;Savas et al, 2020;Zhu et al, 2021). Kombucha is known as anacidic and sweet refreshing beverage obtained from fermented sugared tea (Cardoso et al, 2020) or other substrates such as grape juice (Ayed et al, 2017), soursop (Tan et al, 2020), yarrow (Vitas et al, 2018), coffee (Bueno et al, 2021), and milk (Kruk et al, 2021).…”
