incorporation of functional foods and nutraceuticals such as carotenoids which suffer from poor water solubility and low bioavailability into nano-sized delivery systems can improve their solubility, stability and oral bioavailability. the aim of this study was to prepare β-carotene nanodispersion and investigate the effects of preparation parameters by means of response surface methodology usi...

The effect of the process parameters involved in production bigels was investigated through study structural, mechanical and rheological properties. Four level (24) Central Composite Rotational Design (CCRD) configuration applied order to organogelator concentration, hydrocolloid organogel:hydrogel ratio shear mixing. Gellan gum high oleic sunflower oil with glycerol monostearate were used prod...

The use of immobilized lipase from Candida antarctica (Novozym 435) to catalyze ferulic acid of esterification was investigated in this study. The synthesis product was analyzed using HPLC. The results revealed that the major product was 2-ethylhexyl ferulate. Response surface methodology and 3-level-3-factor central composite rotatable design were adopted to evaluate the effects of synthesis v...

The extruded AZ61A magnesium alloy plates of 6 mm thickness were butt welded using friction stir welding (FSW) process. The corrosion behavior of the welds was evaluated by conducting immersion test in NaCl solution at different pH value, immersion time and chloride ion concentrations. An empirical relationship was established incorporating pH value, immersion time and chloride ion concentratio...

Glazing is a process used to reduce undesirable drying or dehydration of fish during frozen or cold storage. To evaluate the effect of the time/ temperature binomial of the cryogenic frozen tunnel in the amount of glazing watera Central Composite Rotatable Design was used, with application of the Response Surface Methodology. The results reveal that the time/ temperature obtained for pink cusk-...

This paper presents a systematic approach to develop the mathematical model for predicting the ultimate tensile strength, yield strength, and percentage of elongation of AA6351 aluminum alloy which is widely used in automotive, aircraft and defense Industries by incorporating (FSW) friction stir welding process parameter such as tool rotational speed, welding speed, and axial force. FSW has bee...

The seed coat of the legume lupin which is rich in insoluble dietary fibre a major by-product human food applications. Extrusion cooking has been demonstrated to increase desirable soluble Australian sweet coat. In this study, processing condition twin-screw extrusion was optimised using central composite rotatable design from 44.17 g/kg up 113.69 dry basis. high levels polyphenols were retaine...
