A feedlot trial was conducted to determine the effect of dietary vitamin A concentration and roasted soybean (SB) inclusion on carcass characteristics, adipose tissue cellularity, and muscle fatty acid composition. Angus-crossbred steers (n = 168; 295 +/- 1.8 kg) were allotted to 24 pens (7 steers each). Four treatments, in a 2 x 2 factorial arrangement, were investigated: no supplemental vitam...

Fermented pastes of soybeans and soybean-maize blends were evaluated to determine sensory properties driving consumer liking. Pastes composed of 100% soybeans, 90% soybeans and 10% maize, and 75% soybeans and 25% maize were naturally fermented (NFP), and lactic acid bacteria fermented (LFP). Lactic acid bacteria fermentation was achieved through backslopping using a fermented cereal gruel, thob...

The objective of this study was to compare the effects of soybean (SB) meal (SBM) with increased rumen undegradable protein as roasted SB (RSB), extruded SB (ESB) or their equal blend (RSB + ESB) on production performance, nutrient digestibility, N-utilization efficiency, and blood metabolites in mid-lactation dairy cows. Eight lactating Holstein cows (BW = 534 ± 52 and DIM = 104 ± 5; mean ± SD...

The objective of this experiment was to quantify the effects of unroasted or roasted ground-shelled corn (GSC), when fed with alfalfa ensiled in bag, bunker, or O2-limiting tower silos on ruminal digestion and microbial CP synthesis in lactating dairy cows. The roasted corn was heat-treated in a propane-fired roasting system. Alfalfa was harvested as second cutting from fields with regrowth of ...

A set of prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) of individual ingredients and diets used in the poultry feed industry was evaluated. The AMEn values of three energy ingredients (maize, sorghum and defatted maize germ meal), four protein ingredients (soybean meal, maize gluten meal 60% crude protein, integral micronized soy and roasted whole ...

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...

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...
