The effects of microcapsulated docosahexaenoic acid powder (hereinafter DHA powder) on some viscoelastic properties of wheat flour dough and loaf volume were studied. The addition of DHA powder in the range of 0.1 to 0.3% caused a significant increase in the loaf volume of bread after baking. Dough containing 0.2 or 0.3% DHA powder had greater modulus of elasticity, viscosity coefficient and re...

there is some evidence on the effects of organic acids on the functional properties of native starches. however, there is little information on such effects on modified starches. the main objective of this study was to determine the effects of l-ascorbic acid (150 mg kg-1, as the permitted level in bakery products) on functional properties of cross-linked wheat starch. once the starch was treat...

Rice milling plays a key factor in determining rice quality and value. Therefore accurate quality assessments are critical to the rice industry. This study was undertaken to assess the effect of exposing rice to elevated temperatures during milling, on cooked rice texture and rice flour pasting properties. Two long (Cybonnett and Francis) and one medium (Jupiter) rice (oryzae sativa L.) cultiva...

Rice is staple food of Pakistani inhabitants and is a source of foreign exchange earnings. It is an immense source of starch. Rice starch is digested so quickly than any other high starchy food and this aspect make it distinctive among other cereals. The cooking and eating value is determined by the amylose content and gelatinization temperature. The cooking and eating characteristics of rice i...

The objective of this study was to determine the effects on quality of incorporating raspberry and cranberry pomaces into American-style muffins prepared under various baking conditions. The different baking conditions did not affect the texture or microstructure of the control muffins. The enhanced samples baked at 140 °C for 30 min were characterized by a harder texture than the control muffi...

Cryofixation, freeze-etch techniques were used to study the structure of cake batters made from a lean cake formulation before heating and after heating to temperatures up to l00-l02 °C. Batters were prepared without added emulsifiers and with saturated and unsaturated monoglycerides replacing 5 and l 0% of the oil. Unsaturated monoglyceri des were more effective than saturated monoglycerides i...

Starch is the major component of cereal grains and starchy foods, and changes in its biophysical and biochemical properties (e.g., amylose, amylopectin, pasting, gelatinization, viscosity) will have a direct effect on its end use properties (e.g., bread, malt, polymers). The use of rapid and non-destructive methods to study and monitor starch properties, such as gelatinization, retrogradation, ...

The impact of wheat (WT) flour replacement up to 45% (weight basis) by incorporation of ternary blends of teff (T), green pea (GP) and buckwheat (BW) flours on the thermal profiles of quaternary blended dough matrices have been investigated by simulating baking, cooling, and storage in differential scanning calorimeter (DSC) pans. Endothermal transitions related to suitable patterns for low and...

The effect of gelatinization of dietary starch (wheat, corn and potato) on the distribution of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase along the small intestine of rats was studied in villus and crypt cell populations isolated by graduated scraping. Gelatinized starch preferentially stimulated jejunal reductase activity in both villus and crypt cells and consequently retained ...
