plant extracts are rich sources of natural antioxidant and antibacterial compounds. in recent decades, the need for using natural antioxidants in foods, pharmaceuticals and cosmetics has promopted extensive scientific research. the purpose of this study was to investigation of effect of different percentages of rosemary extract (0, 1, 2.5 and 5%) on the quality, chemical and microbial of the pr...

Reduction or elimination of chemically synthesized additives from foods is a current demand in food industry. A new approach to prevent the proliferation of microorganisms or protect food from oxidation is the use of essential oils or plant extracts as natural additives in foods. We have studied antimicrobial activity of rosemary extracts (Rosmarinus officinalis L.) against different species of...

The effects of rosemary extract, chitosan and carnosine, added individually or in combination, on colour, lipid stability and sensory attributes of beef patties were investigated. All samples were stored for up to 15 days at 4 ± 1 oC. Surface colour (Hunter L*, a* and b* values), and lipid oxidation (2-thiobarbituric acid reactive substances) were measured on days 0, 1, 3, 6, 9, 12 and 15 of st...

The use of extracts of rosemary and other spices to combat oxidative rancidity is generating increased interest with consumer concerns over the use of synthetic antioxidants. Spice extracts are of interest because they have the advantage of being labeled as spices or natural flavors. The objective of this study was to evaluate the rancidity inhibition and color stability properties of various a...

background: the rosemary extract (re) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. in this study, we postulated which doses of re have a more effect on the hippocampus of middle-aged rats.   methods : in this experimental study, thirty-two middle-aged male wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of re (containing 40% carnosic ac...

BACKGROUND The aim of the study was to determine the effect of pasteurisation and sterilization of model systems of minced chicken meat in the presence of low or high-oxidised pork lard, soy and sunflower oil, as well as casein hydrolysate and rosemary extract, on losses of thiamine in model systems. METHODS In the samples, the thiamine content was analysed periodically by thiochromium method...

This paper explores the potential of Bourdieu's approach to capital as a way of understanding class dynamics in contemporary capitalism. Recent rethinking of class analysis has sought to move beyond what Rosemary Crompton (1998) calls the 'employment aggregate approach', one which involves categorizing people into class groups according to whether they have certain attributes (e.g. occupations)...
