antioxidant interactions of green tea and rosemary extracts combination

The Antibacterial and Antioxidant Effect of Grape Seed and Green Tea Extracts on Durability of Tilapia

Background: The current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of Tilapia packed inpolyethylene bags, which were kept in cool temperature of 4 ± 1 °C. Methods: Prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (...

effects of green tea, echinacea and rosemary extracts on shelf life of broiler thigh meat

the effect of green tea, echinacea purpurea, rosemary extracts on dilation of oxidation and rancidity development in broiler thigh meat was studied. therefore, fresh thighs were dipped in 0.1%  alcoholic aqueous extract during 15 min and kept frozen (-20°c) until 6 months. sampling was carried out at 1, 30, 60, 90, 120,150 and 180 days of aging at -20°c. a parallel experiment with ascorbic acid...

Supercritical fractionation of rosemary extracts to improve antioxidant activity

A comparative study of the antioxidant scavenging activity of green tea, black tea and coffee extracts: a kinetic approach.

The antioxidant activities of three beverages, coffee, black tea and green tea, along with their major components, were investigated in terms of their reaction with the stable radical 2,2'-diphenyl-2-picrylhydrazyl (DPPH). We used a kinetic approach in parallel with quantification methods based on a fixed end-point to determine the scavenging efficiency of compounds abundant in these beverages ...

Antioxidant activity of black tea vs. green tea.

Dear Editor: A recent article by Leung et al. (1) reported that drinking black tea has benefits equal to those of drinking green tea in terms of their antioxidant capacities because theaflavins present in black tea possess at least the same antioxidant potency as catechins present in green tea. As reported in related studies (2–4), it is clear that a group of theaflavins (TF) in black tea, spec...

Potent Anti-Adipogenic Effect of Green Tea and Green Tea Extracts in Chicken

This study was conducted to examine the effect of green tea on body, adipose tissue, and liver weights and adipose tissue weight to body weight ratio and the adipogenic differentiation and expression of adipogenic transcripts in chicken (Gallus gallus) preadipocytes. In experiment one, chicks were weighed and randomly assigned to a control diet (CTRL) and green tea treatment (GT 1%, w/w) for 38...
