Effects of replacing fish oil with linseed oil or corn oil on growth, fatty acid metabolism and immune responses of juvenile cobia Rachycentron canadumChen, Wei-chih 19 July 2006 (has links)
The effects of partial or total replacement of fish oil with linseed oil or corn oil or both in diets of cobia were valuated. Basal diet was isonitrogenous and isoenergetic and contained 15% crude lipid. Results of the 8-wk feeding trial show that fish fed diet containing only fish oil grew significant better than fish fed other replacement diets (replacement level 33-100%). Fish fed diet containing only plant oil grew the least and had the lowest liver weight, condition factor and body lipid concentration. Oil replacement did not significantly change liver mRNA gene expression of fatty acid desaturase and elongase. As levels of replacement increased, tissue PUFA increased while HUFA decreased. Fish fed all fish oil diet had the highest respiratory burst activities of head kidney phagocytes. Serum of the fish fed the all vegetable oil diets had the lowest lysozyme activities. Fish fed all linseed oil diet had the highest SOD activities. Serum alternative complement pathway activity, aspartate transaminase and alanine transaminase activity did not vary among treatments. The results show that cobia juveniles had relatively high need for fish oil in their diets, and the ability to synthesized HUFA from PUFA was limited. Partial or total replacement (33-100%) of fish oil with linseed oil or corn oil or both were detrimental to fish growth and immune responses.

The utilization of corn germ oilmeal protein by the rat.Oranyeli, Christopher Obiora. January 1964 (has links)
Missing pg.124. / One of the major health problems confronting the emerging nations of the world today is how to obtain a cheap source of high quality protein. Milk, eggs and other proteins of animal origin are the more expensive items of the diet everywhere, and more so in the tropics because of the environmental limitations set on livestock productivity in these countries. Nature has, on the other hand, equipped these countries with highly diversified, nutritionally unexplored protein sources of vegetable origin. [...]

Characterization and Combustion Performance of Corn Oil-Based Biofuel BlendsSavant, Gautam Sandesh 2012 May 1900 (has links)
In recent years, the development and use of biofuels have received considerable attention due to the high demand for environmentally acceptable (green) fuels. Most of the recent studies have looked at the processes of converting vegetable oils into biodiesel. It is well known vegetable oil to biodiesel conversion involves many processes including transesterification, which makes biodiesel costly and time-consuming to produce. In this study, the effects of blending high-viscosity fresh and used corn oils with low-viscosity diesel and jet fuel mixed with butanol and ethanol were studied. Several corn oil-based blends were formulated and characterized to understand the effect of composition on viscosity, fuel stability and energy content. The formulated corn oil blends were combusted in a 30 kW modified combustion chamber to determine the corresponding NOx and CO emission levels, along with CO₂ levels. Used corn oil was made by simply heating fresh corn oil for a fixed period of time (about 44 hours), and was characterized by quantifying its total polar material (TPM), iodine value, free fatty acid content, and peroxide value. The combustion experiments were conducted at a constant heat output of 68,620 kJ/hr (19 kW), to observe and study the effects of equivalence ratio, swirl number, and fuel composition on emissions. Used corn oil blends exhibited better combustion performance than fresh corn oil blends, due in part to the higher unsaturation levels in fresh corn oil. NOx emissions for used corn oil increased with swirl number. Among all the blends, the one with the higher amount of diesel (lower amount of corn oil) showed higher NOx emissions. The blend with fresh corn oil showed decreasing NOx with increasing equivalence ratio at swirl number 1.4. All blends showed generally decreasing CO trends at both swirl numbers at very lean conditions. The diesel fuel component as well as the alcohols in the blends were also important in the production of pollutants. Compared to the diesel-based blends mixed with used corn oil, butanol, and ethanol, the jet fuel-based blends showed higher NOx levels and lower CO levels at both swirl numbers.

Production of biodiesel from corn oil and ethanol by homogeneous alkali catalyzed transesterification / Tillverkning av biodiesel frånj majsolja och etanol genom homogen baskatalyserad transesterifieringMendez, Atahualpa January 2011 (has links)
This report gives a general overview on biodiesel production, its motivations, characteristics and recent developments, mainly focused in the Brazilian case. The Brazilian National Program for Production and Use of Biodiesel (PNPB) launched 2003 created a demand of biodiesel and stimulated the biodiesel production. Biodiesel is being produced from soybean oil, followed by animal fats and cottonseed oil, with palm and castor bean oil contributing in small portions. The biodiesel expansion has impacts on environmental and social issues such as deforestation from soya expansion and a decrease of employment levels due to the high degree of mechanization of the soya harvest. Experimental work was developed, using corn oil, ethanol and NaOH as a catalyst. Experiments were made varying significant parameters to find the optimum reaction temperature, reaction time, catalyst amount and molar ratio between ethanol and corn oil. Besides that, another experiment aimed to describe the yield behavior as a function of the reaction time. The produced biodiesel has been characterized by measurements of density, refraction index and viscosity. The amount of 0.4 wt % NaOH, based on the weight of raw oil, was enough to catalyze the reaction of transesterification effectively. A higher amount of alcohol in excess provides a higher yield at mild temperature conditions. But the higher amount of alcohol used, the higher the amount of alcohol in excess presented in the biodiesel phase which has to be eliminated. An increase of the temperature from 40˚C to 50˚C does not increase the yield in a considerable way. Thus due to the energy saving it is not recommended to increase the temperature to 50˚C. Regarding the evaluation of the conversion as function of time, a high conversion is obtained after 90 min. An extension of the reaction time from 90 to 150min had no significant effect.
