Antioxidants play an important role in food preservation by inhibiting oxidation processes and contributing to health promotion rendered many dietary supplements, nutraceuticals functional ingredients. Antioxidant activity can be monitored a variety of assays with different mechanisms, including hydrogen atom transfer (HAT), single electron (ET), reducing power, metal chelation, among others. Understanding the principle advantages limitations measurement is for proper selection method(s)...
Fresh and sun-dried dates of three native varieties from Oman, namely, Fard, Khasab, Khalas, were examined for their antioxidant activity total contents anthocyanins, carotenoids, phenolics, as well free bound phenolic acids. All results are expressed mean value ± standard deviation (n = 3) on a fresh weight basis. date found to be good source antioxidants (11687−20604 μmol Trolox equiv/g), anthocyanins (0.24−1.52 mg cyanidin 3-glucoside equiv/100 g), carotenoids (1.31−3.03 mg/100 phenolics...
The effect of chitosan with different molecular weights as coatings for shelf-life extension fresh fillets Atlantic cod (Gadus morhua) and herring (Clupea harengus) was evaluated over a 12-day storage at refrigerated temperature (4 ± 1 °C). Three preparations from snow crab (Chinoecetes opilio) processing wastes, differing in viscosities weights, were prepared; their apparent (360, 57, 14 cP) depended on the deacetylation time (4, 10, 20 h, respectively) chitin precursor. Upon coating...
Soluble and insoluble-bound phenolic extracts of several varieties millet (kodo, finger, foxtail, proso, pearl, little millets) whole grains were evaluated for their contents antioxidative efficacy using trolox equivalent antioxidant capacity (TEAC), reducing power (RP), β-carotene−linoleate model system as well ferrous chelating activity. In addition, ferulic p-coumaric acids present in soluble bound fractions millets, determined high-performance liquid chromatography (HPLC) HPLC−mass...
Phenolic compounds from soft and hard wheat their milling fractions were extracted into distilled deionized water, in vitro antioxidant activities evaluated. Wheat samples used as such (nontreated) or subjected to pH adjustment (treated) order simulate gastrointestinal conditions. The total phenolic content (TPC) was determined using Folin−Ciocalteu's procedure. activity (TAA) Trolox equivalent capacity assay expressed equivalents. of extracts also evaluated the β-carotene bleaching assay,...
Gelatin extracted from Alaska pollack skin was hydrolyzed with serial digestions in the order of Alcalase, Pronase E, and collagenase using a three-step recycling membrane reactor. The fraction second step, which composed peptides ranging 1.5 to 4.5 kDa showed high antioxidative activity. Two different showing strong activity were isolated hydrolysate consecutive chromatographic methods including gel filtration on Sephadex G-25 column, ion-exchange chromatography SP-Sephadex C-25...
Four different colored carrots, orange, purple with orange core, yellow, and white, were examined for their content of phenolics, antioxidant vitamins, sugars as well volatiles sensory responses. A total 35 identified in all 27 positively. White carrot contained the highest volatiles, followed by purple, yellow. In total, 11, 16, 10, 9 phenolic compounds determined first time white respectively. Of these, chlorogenic acid was most predominant compound varieties. Differences (p < 0.05)...
