OBJECTIVE To determine the effect of pH, and exposure time over the inactivation of aflatoxin B1 (AFB1) during the tortilla making process as well as the degradative molecules generated. MATERIALS AND METHODS Inactivation of AFB1 in maize-dough with alkaline pH and in alkaline methanolic solutions was determined by HPLC. Kinetics of time exposure of AFB1 in methanolic solution and the degrada...

The link between the intake of dietary fiber (DF) and health benefits has prompted the interest in fiberenriched foods such as fiber-enriched baked goods. A distinction is established between insoluble DF and soluble DF. Insoluble and soluble forms of DF have different compositions resulting in different of nutritional, physiological and technological properties. In this work, the effect of ins...

ABSTRACT: In this research, yeast-salt method was used to make flat bread dough. The yeast used for this process was Saccharomyces cerevisiae (PTCC-Code 5080), that was employed at the concentrations of 0.06% and 0.12% (w/w based on wheat flour). In order to carry out this research, a completely randomized design with three replications was used. Means were compared through Duncan's multiple ra...

A new approach to the forming control using a forming process model of rheological food dough is presented. Manipulative operations of rheological objects can be found in many industrial fields such as food industry and medical product industry. For example, automatic operations of rheological objects such as food dough are eagerly required in food industry. Since food dough deforms during oper...

in present study, a sybr green based real time pcr assay was developed for specific detection and quantification of bacillus subtilis in dough used for bread making. new primer pairs were designed to amplify a 212 base pair fragment of the apre gene. specificity of these primer pairs was confirmed with conventional and real time pcr methods. standard curves constructed using the threshold cycle...

The effect of wheat flour extraction rates on flour composition, farinographic characteristics and the quality of sourdough naans was investigated. The results indicated that by increasing the extraction rate, the amount of protein, fiber, fat and ash increased, whereas moisture content decreased. Farinographic characteristic like water absorption and dough development time increased with an in...

The effect of the dosing vehicle (e.g., dough) on the ability of an in vitro gastrointestinal (IVG) method to predict relative bioavailable Pb associated with soil ingestion was evaluated. Bioaccessible Pb determined by the IVG method was compared with relative bioavailable Pb measured from dosing trials using juvenile swine for 18 contaminated soils ranging from 1270 to 14200 mg Pb kg(-1). Bio...

This paper is concerned with the parallel computation of incompressible viscoelastic rotating flows. Such flows arise in many industrial settings being particularly important in the food industries, for materials such as dough. Here, the material is driven by one or two stirrers, rotating about the centre of a cylindrical vessel, fixed to a lid. The stirrers may be positioned in eccentric arran...

The rheological properties of wheat dough directly influence the texture and appearance of bakery products, and the effect of wheat proteins on flour dough properties is a question attracting considerable interest. We present results that complement this ongoing theoretical scrutiny by empirically relating intrinsic grain properties to end-use flour characteristics. More specifically, we presen...

Wheat storage proteins of twelve winter wheat cultivars grown at the experimental field of the Agricultural Institute Osijek in 2009 were studied for their contribution to the baking quality. Composition of high molecular weight glutenin subunits (HMW-GS) was analyzed by SDS-PAGE method, while the proportions of endosperm storage proteins were determined by RP-HPLC method. Regarding the proport...
