this study was carried out to evaluate the effects of red onion (allium cepa l.) juice and green tea (camellia sinenses) extract on lipid oxidation and sensory characteristics of refrigerated (4ºc) sturgeon fillets (acipenser persicus). fresh fillets were tumbled in 1%, 2.5%, and 5% (v/v) aqueous solutions of onion juice (oj) and tea extract (te), and then stored for up to 8 days at 4°c in a re...

The effects of two types of Welsh onion, green-leafy and white-sheath types, on hyperlipidemia in rats fed on diets high in fat and sucrose were studied. A significant lowering effect on cholesterol in the plasma and on total lipids, triacylglycerol, and cholesterol in the liver was observed in rats fed on the green, but not white, Welsh onion. These Welsh onions had no significant effect on th...

This study was designed to investigate the effects of dietary onion flesh or onion peel on lipid peroxides and DNA damage in aged rats. Sprague Dawley male rats (n=40, 16 mo old) were blocked into five groups and raised for 3 mo with either an onion-free control diet or onion diets (Allium cepa L., intermediate-day variety) containing either 5% (w/w) powdered dried onion flesh, 5% (w/w) powdere...

This study examined the anti-diabetic effect of onion (Allium cepa. Linn) in the streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal rats fed control diet or supplemented with onion powder (7% w/w) and diabetic rats fed control diet or supplemented with onion powder. Diabetes was induced by a single injection of STZ (60 mg/kg, ip) in citrate buffer. The...

The consumption of fruits and vegetables that have high polyphenol content has been previously associated with a reduced risk for cardiovascular disease. We investigated the effects of onion peel extract on plasma total antioxidant capacity, lipid peroxidation, and leukocyte DNA damage. This study was a randomized, double-blind, placebo-controlled, crossover trial. Healthy female subjects recei...

Addition of 0.5% onion was effective in reducing lipid oxidation in irradiated cooked ground beef after 7 day storage. Addition of garlic or onion greatly increased the amounts of sulfur volatiles from cooked ground beef. Irradiation and storage both changed the amounts and compositions of sulfur compounds in both garlic- and onion-added cooked ground beef significantly. Although, addition of g...

OBJECTIVE To describe an optical coherence tomographic finding of layered hyperreflective bands beneath the retinal pigment epithelium (RPE), the so-called onion sign believed to represent lipid within a vascularized pigment epithelial detachment. METHODS This retrospective observational case series involved reviewing clinical histories of patients with the onion sign. Imaging studies analyzed ...

The levels and roles of lipid mediators can be modified in response to nutritional stimuli. The aim of this study was to investigate shifts in oxylipin and sphingolipid profiles stimulated by a hypercholesterolemic (HC) diet along with the modulating effects of onion introduced as an antioxidant functional ingredient characterized in the diet (HCO). Oxylipin and sphingolipid profiles were deter...

Poultry products are comparatively rich in cholesterol. WHO report indicates incidence of coronary heart disease and high dietary cholesterol level to be positively correlated. In such a situation, decreasing the cholesterol content in poultry products would be appropriate. Onion and garlic are ascribed with therapeutic effects such as hypocholesterolemia, hypolipidemia and immunosuppressant ac...

Objective: This study aims to evaluate the effects of onion (Allium cepa L.) against hyperglycaemia and dyslipidemia and determine possible changes in these effects due to different heat treatments applied to onion. Materials and Methods: 32 male Wistar-albino rats were divided into 4 groups as follows: the groups C and DC were fed with standard rat diet;...
