The objective of this work was to study the effect of different dietary fibers on rheological properties of yoghurts fortified with these fibers [1,2,3]. Commercial fibers from apple and inulin were used. The effect of addition of dietary fibers in yoghurt [4,5] was investigated by a rotational viscometer, Brookfield viscometer (Brookfield Engineering Inc., Model RV-DV I Prime) with RV spindles. The Brookfield viscometer DV I Prime with disk spindles represents an easy and cheap method for rheological characterization of non-Newtonian fluids, in this case of yoghurt. Syneresis and pH did not show any difference, while only apple fiber yoghurt showed colour differences compared to control.

“…Taking into account that diesel fuel is a mixture of hydrocarbons, and biodiesel is a mixture of esters, diesel fuel+biodiesel mixtures can be considered as pseudo-binary mixtures [14]. When applying these equations to diesel fuel+biodiesel blends, volume fractions were used instead of molar fractions, to express blend composition.…”

For now, biodiesel is the commonly accepted biofuel as a substitute for diesel fuel in internal combustion engines. Diesel fuel blends with up to 20% biodiesel can be used in diesel engines without any modification. A lot of studies regarding diesel fuel+biodiesel blends properties are presented in the literature. Some of the important properties of diesel fuel+biodiesel blends can be evaluated from other blends properties. For example, density and viscosity of biodiesel blends can be predicted based on blend refractive index. More than that, refractive index can be used as a reliable physical property to predict transesterification reaction progress. As a result, the refractive index of diesel fuel+biodiesel blends is important in order to characterize these blends or to monitor the evolution of transesterification process of vegetable oils or animal fats. The refractive index of diesel fuel+biodiesel blends can be experimentally determined or evaluated based on refractive indices of diesel fuel and biodiesel. The aim of this study was to estimate the accuracy of refractive index of diesel fuel +biodiesel blends calculation, using models initially proposed to evaluate the refractive index of a binary liquid mixture. It was shown that the refractive index of diesel fuel+biodiesel blends can be accurately predicted from refractive indices of the components of the blend. Wiener, Heller and Edward equations can be recommended to predict with a great accuracy the refractive index of diesel fuel+biodiesel blends.

“…A standard spindle was immersed into the sample; the temperature and speed of the viscometer were set at 40 o C and 30 rev/min respectively. The viscometer was switched on and allowed to rotate for 20 minutes, and then the value of viscosity was taken on the displayed screen [12].…”

The search for alternative and renewable fuels has increased globally in recent times owing to the increasing pressure to reduce greenhouse gas. In this work, biodiesel was produced from soya bean oil via transesterification with methanol in the presence of catalyst (sodium hydroxide). The biodiesel was purified adopting the wet purification method. The clean biodiesel was characterised by determining some physico-chemical parameters such as density, flash point, viscosity, free fatty acid (FFA), cloud point, pour point, saponification value and cetane number. The results obtained show that most of the parameters tested fell within the standard ranges as specified by the ASTM. D6751 and EN 14214. The transesterification of soya bean oil has significantly reduced the viscosity, acid value and flash point of the oil by 66.4%, 71.6% and 55.7% respectively. The cetane number was however on the higher range of the standard values; this is an indication that the biodiesel has a good fuel ignition property. It is therefore ascertained that the biodiesel from soya bean oil is a viable alternative to petroleum diesel, since all the quality parameters are within the standard values.
