Lysates of protoplasts from the endosperm of developing grains of wheat (Triticum aestivum) were fractionated on density gradients of Nycodenz to give amyloplasts. Enzyme distribution on the gradients suggested that: (i) starch synthase and ADP-glucose pyrophosphorylase are confined to the amyloplasts; (ii) pyrophosphate: fructose-6-phosphate 1-phosphotransferase and UDP-glucose pyrophosphoryla...

The endosperm of hexaploid wheat (Triticum aestivum [L.]) was shown to contain a high molecular weight starch synthase (SS) analogous to the product of the maize du1 gene, starch synthase III (SSIII; DU1). cDNA and genomic DNA sequences encoding wheat SSIII were isolated and characterized. The wheat SSIII cDNA is 5,346 bp long and contains an open reading frame that encodes a 1,628-amino acid p...

Yellow field pea (Pisum sativum L.) fractions that were mainly protein (50%), fibre (90%) or starch (85%) were obtained from a commercial pea mill and mixed with wheat kernels or wheat flour. Based on the mortality and the number of offspring produced, protein-rich pea flour was more toxic than fibre, which was more toxic than starch. For the protein-rich pea flour mixed with wheat kernels, the...

DESCRIPTION Zopiclone is a fine white or slightly cream crystalline powder with a melting point of 176-178°C. It is practically insoluble in acetone, soluble in dimethyl formamide and 0.1N hydrochloric acid and freely soluble in chloroform and dichloromethane. Imovane tablets contain 7.5 mg of the active ingredient zopiclone. The tablets also contain lactose, calcium hydrogen phosphate, wheat s...

Cereal Chem. 80(3):316–322 Reflectance spectra (400 to 1700 nm) of single wheat kernels collected using the Single Kernel Characterization System (SKCS) 4170 were analyzed for wheat grain hardness using partial least squares (PLS) regression. The wavelengths (650 to 700, 1100, 1200, 1380, 1450, and 1670 nm) that contributed most to the ability of the model to predict hardness were related to pr...

Physico-chemical properties of dietary fibres might be involved in metabolic control, particularly of the postprandial blood glucose response. The aim of the present study was to look at the effects of the content of soluble fibres and of the particle size of solid fibres on in vitro and in vivo starch hydrolysis and on the subsequent glucose absorption as well as the triacylglycerolaemia. Two ...

This study was aimed to find the formulation of composite flours from rice, cassava, and soybean flours, potato starch, and hydrocolloids, and also to find the egg replacer formulation from whey and soybean protein isolate. The composite flours and egg replacer then were used as wheat flour and egg alternatives in cake production, and some physicochemical and functional properties of the treate...

Some physicochemical and rheological properties of jackfruit seed flour and starch, isolated from the flour were investigated. The flour had good capacities for water absorption (205%) and oil absorption (93%). Substitution of wheat flour with the seed flour, at the level of 5, 10 and 20% markedly reduced the gluten strength of the mixed dough. The Brabender amylogram (6% concentration, db) of ...

The effect of recrystallization temperature on the lamellar structure of RSIII samples was studied using XRD and SAXS. The polymorph type could be manipulated in a controlled manner, independently of the plant source. In RSIII from corn starch and from high-amylose corn starch, retrogradation at a low temperature led to the formation of polymorph B with lamellas arranged in long-range periodici...

A variety of feedstocks are used to produce ethanol and DDGS around the world. Grains, such as corn, wheat, and barley vary in starch content (Table 1), and those with the greatest amount of starch (e.g. corn) are used to a greater extent because they provide the greatest ethanol yield. Since the nutrient composition of grains used to produce ethanol varies, the nutrient composition of the resu...
