T H A T genetic mutations are prerequisite to evolution of the species is well recognized. The mechanism by which such mutations are segregated and recombined in bisexual species forms a large part of classical genetics. Less well known are the modifications, in unisexual species, of the same mechanisms to attain comparable ends. The segregation of genes in aberrant cases of diploid parthenogen...

In this work sensory characteristics of cookies with different amount of chestnut flour were determined by sensory and instrumental methods. The wheat flour for cookies was substituted with chestnut flour in three different levels (20, 40 and 60%) and the dough moisture was 22%. The control sample was with 100% of wheat flour. Sensory quality of the cookies was described using quantity descript...

INTRODUCTION This study was undertaken with the objectives of formulating composite bread by utilising finger millet flour and foxtail millet flour and further to evaluate these breads for sensory, nutritional qualities, and glycemic response. METHODS Two genotypes of finger millet VL-146 and PRM-601 and one local cultivar of foxtail millet were studied. The finger millet flour (FMF) and foxt...

Gluten-free pancakes were prepared using rice flour and rice flour replaced with various amounts, at 10, 20 and 40%, of sweet potato flour. Textural properties of the cooked pancakes, such as hardness and chewiness generally increased with time after cooking, whereas they decreased with increased sweet potato flour replacement. On the other hand, cohesiveness decreased with time, but increased ...

Food snack products were prepared by a combination of flour composition and ingredient recipes. A popular trend in replacing wheat flour with rice flour was proposed in the consumer food manufacturing industries for improvement in quality and nutritional value. The effect of variations in flour combination and sugar and fat replacers on the physical (texture and color) and chemical properties (...

The effects of replacing wheat flour with 0-15% debittered moringa seed (DBMS) flour on the dough rheology of wheat flour and physical, sensory and chemical properties of bread were studied. Incorporation of an increasing amount of DBMS from 0 to 15% decreased farinograph water absorption, dough stability, amylograph peak viscosity and overall quality of bread. The bread with 10% DBMS had a typ...

Zeng J., Gao H., Li G., Liang X. (2011): Extruded corn flour changed the functionality behaviour of blends. Czech J. Food Sci., 29: 520–527. Functionalities and relationships between raw and extruded maize flour blends were studied. The extruded flour had higher water absorption and water solubility indices, and had no differential scanning calorimetry endotherm. The parameters of RVA peak, bre...

Functional properties of cowpea flour from seeds micronised at two different surface temperatures (130 and 170 °C) were studied. Micronisation (130 and 170 °C) significantly (P 0.05) increased the water absorption capacity and least gelation concentration of the flour. The treatment significantly (P 0.05) reduced the water solubility and swelling indices, gel strength and foaming capacity of th...

in laboratory experiments the toxicity of acetone was investigated against four species of stored-product insects. in empty-space trials, estimates of the lethal concentrations of acetone (lc, 72-h exposure) for 50% mortality against adults of the lesser grain borer, rhizopertha dominica (f.), red flour beetle, tribolium castaneum (herbst), rice weevil, si-tophilus oryzae (l.) and eggs of the a...
