Experiments were conducted to develop low-fat soft dough biscuits using carbohydrate-based fat replacers (maltodextrin and guar gum). A central composite rotatable design was used to optimise the level of sugar 24-36%, composite fat (fat 10.5-24.5%, maltodextrin 10.4-24%, and guar gum 0.1-0.5%), ammonium bicarbonate 0.5-2.5%, and water 20-24% for production of low-fat biscuits. Diameter (P < 0....

Abstract This work aims to identify the best treatment condition for removal of chemical oxigen demand (COD) and increase biodegradability in an advanced oxidative process photocatalytic ozonation with titanium dioxide (TiO2), applied remediation leachate produced at municipal landfill Campo Mourao, Parana. The experiment was carried out using a chamber system based on corona effect. A statisti...

The effect of in vitro gastrointestinal digestion on the release microencapsulated phenolic compounds was evaluated through an optimized spray drying process. A stock extract oregano developed and a dryer following central composite rotatable design, controlling variables, inlet temperature (111.7-168.2°C), percentage wall material (5.8-34.1%). Optimum conditions for were decided based differen...

The cutting forces exerted by the cutting tool on the work piece during a machining action to be identified in order to control the tool wear and occurrence of vibration, thus to improve tool-life. Modeling of cutting force in milling is often needed in machining automation. The objective of this study is to predict the effects of cutting parameters on the variations of cutting forces during en...

Abstract—The composite flour blend consisting of corn, pearl millet, black gram and wheat bran in the ratio of 80:5:10:5 was taken to prepare the extruded product and their effect on physical properties of extrudate was studied. The extrusion process was conducted in laboratory by using twin screw extruder. The physical characteristics evaluated include lateral expansion, bulk density, water ab...

The demand for food production brings with it the increase of effluent generation, which represents a great problem slaughterhouses, since effluents contain higher organic load, requiring adequate treatment to decrease environmental impacts. This study examines an alternative solve this problem: application electrocoagulation in anaerobic slaughterhouse and packing plant effluents, as promising...

Optimization of process variables has become very vital in oil extraction processes to obtain maximum yield from oilseeds and nuts. This work focussed on the optimization sandbox seed by mechanical expression. Effects moisture content, roasting temperature, time, expression pressure time was studied using a 5×5 Central Composite Rotatable Design Response Surface Methodology experimental design....
