Weedy Amaranthus species frequently cause economically significant reductions in crop yields. Accurate identification of Amaranthus species is important for efficient weed control, but Amaranthus species can interbreed, which might cause difficulty when identifying hybrid-derived specimens. To determine which of several economically important weedy Amaranthus species are most genetically simila...

A diet with low glycemic index (GI) has a preventive potential against the development of type 2 diabetes and cardiovascular disease. Moreover, low GI foods reduce hunger and result in a lower energy intake which finally leads to positive weight management. We investigate the GI of cereals containing amaranth, measured the postprandial subjective satiety and analyzed the glucose release in a ga...

The mechanism of interaction between food dye amaranth and human serum albumin (HSA) in physiological buffer (pH 7.4) was investigated by fluorescence, UV-vis absorption, circular dichroism (CD), and Fourier transform infrared (FT-IR) spectroscopy. Results obtained from analysis of fluorescence spectra indicated that amaranth had a strong ability to quench the intrinsic fluorescence of HSA thro...

Polyporus sp. S133 decolorized the Amaranth in 72 h (30 mg L(-1)) under static and shaking conditions. Liquid medium containing glucose has shown the highest decolorization of Amaranth by Polyporus sp. S133. When the effect of increasing inoculum concentration on decolorization of Amaranth was studied, maximum decolorization was observed with 15 % inoculum concentration. Significant increase in...

The nutritional value of raw and autoclaved grain amaranth, its milling fractions (perisperm and bran), fat-free flour, and of popped amaranth was evaluated for growing chickens. The control diet, which was composed primarily of corn and soybean meal, contained 3.06 kcal apparent ME (AME)/g and 23.6% CP. Test diets contained about the same AME and CP levels, and the following levels of the test...

This study reports the new functional property of amaranth grain against diet-induced endothelial dysfunction in rabbits. Twenty-seven New Zealand rabbits were fed either a standard diet (SD/G1) or a hypercholesterolemic diet (Hichol) for 28 days. On day 29, the Hichol group was subdivided into four groups and begun receiving the following diets for 21 days: G2: SD + amaranth, G3: Hichol + amar...

Amaranth ( sp.) is a C plant adapted to poor soils and regions with limited rainfall and high temperatures. The plant is characterized by a yield of up to 85 t/ha, CP concentration of up to 28.5% of DM, and DM digestibility of 59 to 79%, which may vary depending on the species and variety. The potential of this plant as a forage source for ruminants has not been completely considered. This stud...

Both spiny and edible amaranths (Amaranthus spinosus and A. tricolor) are exotic annuals in China that produce numerous small seeds every year. Spiny amaranth has become a successful invader and a troublesome weed in Xishuangbanna, but edible amaranth has not, although it is widely grown as a vegetable there. As seed germination is one of the most important life-stages contributing to the abili...

The kinetics of the oxidative decolorization of amaranth with KBrO3 acidified by H2SO4 was followed up by monitoring the decrease of the absorbance of amaranth at max = 520 nm. The reaction was carried out under pseudo-first-order conditions. The concentration of BrO3 was ca 300 greater than that of amaranth. The rate of reaction increased with increasing concentration of H2SO4 and BrO3, while...
