To enhance the protease production and decrease cost, corn flour and soy peptone were screened as cheap raw materials for the production of extracellular proteases by Bacillus strains. Their compositions in the medium suitable for enzyme production of Bacillus sp. B001 were optimized using statistical experiment designs. Under the optimized conditions, the protease production of Bacillus sp. B0...

nowadays, people tend to consume functional foods for the treatment and prevention of diseases. production growth of functional foods obliged scientists to research about production, distribution and preservation conditions of these products. use of probiotic microorganisms in soy-based products may have advantages of both probiotics and soy on the human health. the probiotic soy-based ice-crea...

In this study, the effects of grape seed flour on the physical-chemical properties, microbiological and sensory properties of Turkish dry fermented sausage, sucuk, was investigated. After the sausages produced with beef, beef fat, sheep tail fat and spices, they were ripened for 14 d. Then they were vacuum-packaged and stored for 80 d at 4℃. The effects of grape seed flour (GSF; 0%, 0.75%, 1.5%...

A new approach was applied with the aim at producing plant protein hydrolysates less heterogeneous and less contaminated with nonpeptide substances than are the presently available digests. A significant reduction of nonprotein contaminants was achieved by extraction of the plant material, soy flour or wheat flour, with acetone prior to isolation of the protein. Enzymes of nonanimal origin, pap...

Saccharomyces cerevisiae S1, which is a locally isolated and improved strain showed viability at 40, 45 and 50°C and produced ethanol at 40, 43 and 45°C. When the cells were given heat shock at 45°C for 30min and grown at 40°C, 100% viability was observed for 60h, and addition of 200gL(-1) ethanol has led to complete cell death at 30h. Heat shock given at 45°C (for 30min) has improved the toler...

BACKGROUND African locust bean tree is an important food tree for both human and livestock such as husks and pods. It plays a very vital role in the rural areas. The aim of this study was to evaluate some physicochemical, mineral characteristics and functional properties of flour and starch extract produced from Parkia biglobosa seeds, using different methods. MATERIALS AND METHODS Three diff...

introduction using vegetable oils and animal fats in poultry diets have beneficial effects for poultry production. they often have higher biological value than expected, increasing dietary metabolizable energy, which usually results in higher growth rates and better feed efficiency. sterol-regulatory element binding proteins (srebps) play a key role in transcriptional regulation of cholesterol ...

The aim of this research was to study the effect of fortified pan bread with Lupine flour (5, 10 and 15 %) on the chemical, rheological and nutritional properties. Lupine flour showed higher levels of crude protein, ash, crude fat and fiber than the wheat flour. Conversely, wheat flour showed higher contents in carbohydrates. Rheological studies of dough showed clear differences between wheat f...

Dry heat was used to inactivate Salmonella newington, Salmonella typhimurium, Salmonella anatum, Salmonella kentucky, Salmonella cubana, Salmonella seftenberg, Salmonella thompson, and Salmonella tennessee in corn flour at 10 and 15% moisture. The flour was spray inoculated at 10(5) Salmonella cells per g and then stored at 49 degrees C (120 degrees F); viable Salmonella cells were counted on T...

The effects of soaking and roasting on the physicochemical and pasting properties of soybean flour were evaluated. Soybean seeds were soaked overnight in tap water for 0-72 h, hand dehulled, dried, and part of the sample was roasted. Roasted and unroasted soy beans were milled into flour and analyzed. The results showed that the total carbohydrates (22.8-27.9 g/100 g), the ash content (3.5-3.6 ...
