The pattern of genetic differentiation among experimental populations of the flour beetle Tribolium castaneum suggested the hypothesis that relative fitness of three genotypes at the PGM-1 locus (or other linked loci) depends directly on diet. This hypothesis was tested by measuring several fitness components (developmental time, survival, fecundity, rate of egg cannibalism) on groups of indivi...

The influences of different variables on the viscosity and gel formation of the konjac flour produced from Amorphophallus oncophyllus have been studied. At the concentration studied, the 1.5% konjac flour yielded a viscous solution than that of 0.5% konjac flour. The viscosity of konjac flour solution were unaffected by pH (pH 2 to pH 8), salt concentration (0-10% w/v), and high acid (pH 3.5) /...

Pretreatment of lignocellulosic biomass by N-methylmorpholine-N-oxide (NMMO), a solvent used in the textile industry to dissolve cellulose for production of regenerated cellulose fibers, was observed to enhance significantly enzymatic saccharification and fermentation. The enhancement was speculated to have been caused by reduced cellulose crystallinity after dissolution and precipitation proce...

This study presents influence of millet flour blend on physical, functional, nutritional, cooking and organoleptic characteristics of noodles prepared from composite flour of millet flour blend, whole wheat flour and soy flour. Fiber and amylose/ amylopectin ratio increased significantly (p<0.05) with increase in level of millet flour blend incorporation. Cooking time of developed noodles from ...

The physicochemical and sensory properties of peanut spreads fortified with soy flour were studied. Peanut spreads were replaced by whole soybean flour and soy nut flour at 0, 5, 15, 20 and 30% (w/w). All samples were analyzed for fat, protein, sugar, moisture content, adhesiveness, cohesiveness, hardness and sensory characteristics. Replacing peanut spread with soy flour had significant effect...

The fortified of soft wheat flour with cowpea flour in bread making was investigated. The Soft wheat flour (SWF) was substituted by cowpea flour at levels of 5, 15 and 20%. The protein content of composite breads ranged from 6.1 – 9.9%. Significant difference was observed in moisture, protein and crude fibre contents of control (wheat bread) and composite bread at 5% addition of cowpea. Water a...

Trichogramma brassicae (Bezdenko) is the most important species of Trichogramma parasitoids in Iran. The cotton bollworm, Helicoverpa armigera (Hubner) is a polyphagous insect pest that attacks many crops including cotton, maize, soybean, tomato, etc. The bollworm egg is a suitable target for many Trichogramma species. Factitious hosts such as eggs of the flour moth, Anagasta kuehniella (Zeller...

_________________________________________________________________ ABSTRACT Brown flour was developed by incorporating different proportions of wheat bran i.e. 0, 5, 10, 15 and 20% into the residual flour (milling by-product of pizza flour). Each treatment of brown flour, wheat bran and whole wheat flour was subjected for proximate composition and iron content. The highest iron content was obser...

This paper reports on the experimental determination of the thermal conductivities of some selected powdered food stuffs and their mixtures. The foodstuffs considered are: guinea corn flour, rice flour, maize flour, beans flour, cassava flour and yam flour. One to one mixtures of these foodstuffs were made in equal ratios to give mixtures of rice and beans flour, cassava and guinea corn flour a...
