Roasted and non roasted full fat or partially defatted flaxseed flours (Linum Usitatissimum) were evaluated for their proximate composition, mineral profile and functional properties. Significant increase in the crude protein, crude fiber, ash and mineral contents in the partially defatted flaxseed flours (both roasted and non-roasted) was observed. Partial defattening improved the foam capacit...

Roasted stem tea has a characteristic flavour, which is obtained by roasting tea stems, by-product of green tea production. The difference between roasted stem and leaf tea derived from the same tea plants were investigated using GC–MS. Pyrazine compounds exhibited a roasted odour and high flavour dilution (FD) factors, as determined via aroma extract dilution analysis (AEDA). Roasted stem tea ...

The effect of a traditional Ethiopian lupin processing method on the chemical composition of lupin seed samples was studied. Two sampling districts, namely Mecha and Sekela, representing the mid- and high-altitude areas of north-western Ethiopia, respectively, were randomly selected. Different types of traditionally processed and marketed lupin seed samples (raw, roasted, and finished) were col...

Oleang, a Thai coffee drink, contained roasted robusta coffee and several roasted grains and seeds. In this research the typical ingredients of oleang that were robusta coffee, corn, soybean, rice, sesame and brown sugar, were roasted and studied for their volatile compounds. Coffee, corn, sesame, and brown sugar were roasted at 220°C for 20 min and soybean and rice were roasted at 240°C for 20...

Two antioxidative compounds were isolated from the oil of sesame seeds roasted at 230°C for 15 min and identified as sesaminols (isomers) by MS and NMR analysis. Although sesaminols are present in refined unroasted sesame seed oil, we have demonstrated their presence also in the oil from the roasted sesame seed without refining for the first time. Furthermore, the amounts of sesaminols in sesam...

Effect of flaxseeds supplementation on serum lipid profile of selected hypercholesteremic patients was studied. Flaxseeds were processed (roasted) and analysed for its nutritional and fatty acid profile and incorporated into chapattis (15gms) and evaluated organoleptically. Administration of roasted Flaxseed powder of 15 gm for 4 weeks produces significant (P<0.001) reduction of serum total cho...

The antioxidant activity of roasted coffee residues was evaluated. Extraction with four solvents (water, methanol, ethanol, and n-hexane) showed that water extracts of roasted coffee residues (WERCR) produced higher yields and gave better protection for lipid peroxidation. WERCR showed a remarkable protective effect on oxidative damage of protein. In addition, WERCR showed scavenging of free ra...

BACKGROUND Almonds contain considerable amounts of potential prebiotic components, and the roasting process may alter these components. The aim of this study was to compare the in vitro fermentation properties and in vivo prebiotic effect of raw and roasted almonds. RESULTS In vitro, predigested raw and roasted almonds promoted the growth of Lactobacillus acidophilus (La-14) and Bifidobacteri...

In vitro antioxidant activities and neuronal cell protective effects of ethanol extract from roasted coffee beans were investigated. Colombia arabica coffee (Coffea arabica) green beans were roasted to give medium (230°C, 10 min), city (230°C, 12 min) and french (230°C, 15 min) coffee beans. Total phenolics in raw green beans, medium, city and french-roasted beans were 8.81±0.05, 9.77±0.03, 9.9...
