Flavonols, anthocyanins, and radical-scavenging activity of two Portuguese onion cultivars (Branca da Póvoa, white; and Vermelha da Póvoa, red) were evaluated simulating domestic freezing conditions (...
We evaluated the effect of three different cooking methods on antioxidant content and radical scavenging activity of sweet corn. Both fresh and frozen sweet corn kernels were boiled, microwaved, and s...
Radical-Scavenging Activities of Fish and Fishery Products     radical-scavenging activity  fish  fishery product       font style='font-size:12px;'> 2009/7/7
A total of 45 Japanese and Bangladeshi water fish and fishery products were investigated for radical-scavenging activity using a 1,1-diphenyl-2-picrylhydrazyl-HPLC method. Among the 35 Japanese fish a...
Water extracts and 50% ethanol extracts of 14 samples of sufu (fermented tofu) produced in various regions of China were prepared, and their DPPH (α,α-Diphenyl-β-pricryl-hydrazyl) radical-scavenging a...
To evaluate fish as free radical scavengers in the human diet, we examined the radical-scavenging activity of some marine fish tissue commonly consumed in Japan, using the 1,1-diphenyl-2-picrylhydrazy...
The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and polyphenol content of 25 dried fruits were evaluated and compared with fresh fruits. The contribution of ascorbic acid to this ...
The radical-scavenging activity of vegetables was measured using the 1,1-diphenyl-2-picrylhydrazyl-HPLC method, and the effect of cooking on this activity was determined. The content of ascorbic acid ...
The radical scavenging activity of the Japanese late-fermented black tea, Toyama Kurocha, was investigated. The activity was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, and its radi...
After the operation of boiling soybean [Glycine max (L.) Merr.], 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activities of soybean cultivars with different seed coat colors of yellow, green, red-b...
The influence of polyphenol oxidase and ascorbate oxidase on radical-scavenging activity and contents of total phenol, chlorogenic acid, and ascorbic acid in vegetables during the cooking process were...
We investigated the 1,1-diphenyl-2-picrylhydrazyl (DPPH)-radical-scavenging activity and antimutagenicity of alcoholic fermented beverages produced from cooked or raw purple-fleshed sweet potato (Ipom...
Free Radical Scavenging Activities of γ-Oryzanol Constituents     DPPH radicals  scavenging activity  γ-oryzanol       font style='font-size:12px;'> 2009/6/10
γ-Oryzanol extracted from brown rice as a free radical scavenger was separated into four constituents, which were identified as cycloartenyl ferulate, 24-methylenecycroartanyl ferulate, β-sitosteryl f...
A rapid and sensitive method for evaluation of the radical-scavenging activity, which uses 2,2′-azobis (2-amidinopropane) dihydrochloride (AAPH) as a radical generator in combination with a luminol ch...
We prepared fermented lemon peel (FLP) with high antioxidative activity by fermentation of the lemon peel (LP) with Aspergillus saitoi. The antioxidative activity of LP and FLP was examined by the rad...
Orange-fleshed sweet potato (OR-SP) cultivars rich in β-carotene are considered to exhibit higher antioxidant capacity than yellow-fleshed sweet potato (YE-SP) cultivars, consumed commonly in Japan. H...
