Grain protein films plasticized with glycerol were prepared from corn zein (CZ), wheat gluten (WG), and a 2.3:1 mixture of wheat gluten and soy protein isolate (WG/SPI). Moisture adsorption curves of the three types of protein films at 25° C and within an approximate water activity range of 0.11 to 0.84 were obtained using a static gravimetric method. The Smith, Oswin, Halsey, and Guggenheim-An...

Outbreaks of salmonellosis and recalls of low-moisture foods including extruded products highlight the need for the food and feed industries to validate their extrusion processes to ensure the destruction of pathogenic microorganisms. Response surface methodology was employed to study the effect of moisture and temperature on inactivation by extrusion of Enterococcus faecium NRRL B-2354 in a c...

The relationship of albumen height (AH) to the compositions of yolks and embryos in hatching eggs from a young (30 wk of age) broiler breeder flock was evaluated during incubation. On Day 2 of incubation, egg weight, yolk weight, and yolk moisture, lipid, and fatty acid contents were determined in eggs from broiler breeders previously identified as laying eggs of either low or high AH. In addit...

background: increase in aquatic production is dependent on raw materials, quality of diet, feed manufacture technology and optimum feed formulation. objectives: the aim of this study was investigation and quality control feed of fft, gft1 and gft2 of rainbow trout in farm and fish feed factory producers in chaharmahal and bakhtiari province. methods: in this study samples of fft, gft1 and gft2 ...

The cactus prickly pears rich in micronutrients, has recently generated a great deal of consumer interest, therefore, this paper was designed to study its physical and chemical compositions such as: moisture, sugar content, total fibres, protein, ash, pH, acidity, minerals contents and total phenolics contents of nine prickly pear juices. Polyphenols are antioxidants who contribute to the nutri...

In recent years, the intermediate-moisture foods (IMF), such as nutrition and energy bars, are a rapidly growing segment of the global food market. However, due to moisture-induced protein aggregation, commercial high protein nutrition bars generally become harder over time, thus losing product acceptability. In this study, the objectives were to investigate the moisture-induced protein aggrega...

introduction: at least 60% of the estimated 300,000 metric tons of tuna that are processed in iran areby-products which arebeingwasted and converted to non-human products as fish meal or fertilizers. therefore, a major challenge facing the tuna canning industry is to find the new processes to utilize tuna processing by-products (mainly dark muscle) into valuable foods. the characteristics of tu...

a study was performed to study the effect of drought stress on protein changes of five wheat genotypes. wheat genotypes were planted in early november, growing season of 2008-2009. the experiment was carried out in a factotial design with three replications. two drought stress levels (irrigated and non irrigated) and five genotype of wheat (f103-l-1-12//pony/opata, f1.158/fdl//blo/3/sh14414/cro...

In this study the nutritional values of three woody leafy vegetables commonly consumed in the south eastern Nigeria were investigated. Fresh edible leaves of Heinsia crinata, Lasienthera africana and Pterocarpus mildbraedii were collected from the wild stands. Proximate analyses were carried out to evaluate their nutritional values vis-à-vis moisture, ash, fibre, protein, lipid, carbohydrate an...
