Palm oil is one of the major fats and oils produced and traded in the world today. It forms an important ingredient in the diet of many people in West Africa. The quality of palm oil is mostly determined by the fatty acid, moisture and impurity content, and bleachability. This study examined the quality of palm oil produced at cottage industry level in Ghana with a view to improve its quality t...

BACKGROUND Effects of palm olein (POL) on calcium and fat metabolic balance and gastrointestinal (GI) tolerance have been clinically evaluated but its use in combination with palm kernel oil (PKO), and canola oil has not been similarly assessed in infants. METHODS Calcium and fat balance and GI tolerance were evaluated in 33 healthy term infants (age = 68-159 d) in a randomized, double-blinde...

Agricultural expansion is one of the major drivers of tropical biodiversity loss worldwide (Foley et al., 2005; Green et al., 2005). Oil palm cultivation is among the main culprits, owing to its huge increase in cultivation in recent years (Food and Agriculture Organisation of the United Nations [FAO], 2011) and its centre of production being within the most biodiverse regions and habitats on t...

Fatty acids esters were produced from two Nigerian lauric oils, palm kernel oil and coconut oil, by transesterification of the oils with different alcohols using PS30 lipase as a catalyst. In the conversion of palm kernel oil to alkyl esters (biodiesel), ethanol gave the highest conversion of 72%, t-butanol 62%, 1-butanol 42%, n-propanol 42% and iso-propanol 24%, while only 15% methyl ester was...

An environmental friendly palm-grease has already been formulated from modified RBDPO (Refined Bleach Deodorized Palm Oil) as base oil and lithium soap as thickener. Such palm-grease is dedicated for general application and or equipment working in areas where biodegradability is required such as in agriculture, forestry and coastal marine, recreation areas. The grease was manufactured via 4 ste...

In this study, a novel continuous reactor has been developed to produce high quality methyl esters (biodiesel) from palm oil. A microporous TiO2/Al2O3 membrane was packed with potassium hydroxide catalyst supported on palm shell activated carbon. The central composite design (CCD) of response surface methodology (RSM) was employed to investigate the effects of reaction temperature, catalyst amo...

The influence of fatty acid composition and tocopherol on cholesterol oxidation in fish, flax, sunflower, and palm oil to which cholesterol was added were examined during storage and heating. The contents of cholesterol oxides in all oils increased (p < 0.05) during storage and heating. Total cholesterol oxides in fish oil were higher (p < 0.05) than that in vegetable oils. Addition of R-tocoph...

The availability of about 18 million hectares of grassland in Pará State, Brazil, and the possibility of increasing the livestock density display a good perspective for the oil palm expansion in pasture land. A life cycle assessment is performed for a prospective palm-based biorefinery to view two regional and one global environmental impact and the consequences of the land-use change in terms ...

Blending helps extend the range of application of oils and fats. This is because most natural oils and fats have limited applications in their original form. Natural oils and fats may need to be modified to suit a particular product formulation. Blending is the simplest method used to modify oils and fats. From the palm fruits, a wide range of products can be derived including palm oil, palm ol...

The aim of the study was to determine an influence of diet additives in a form of protected palm oil, protected fish oil or unprotected fish oil with glycerol in Polish Holstein-Friesian cows on milk fatty acid composition, metabolism, milk yield and milk composition. Milk production, milk fat, and milk protein did not differ statistically between the groups. A significant increase (P<0.01) in ...
