studies have shown that oxygenated compounds and tss are important in food products. it seems that cultivars have a profound influence on these factors. the goal of the present study is to investigate on flavor components and juice quality parameters of two mandarin cultivars. in the last week of january 2012, at least 10 mature fruit were collected and their peel oil was extracted using cold-p...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...

________________________________________________________________________________ Abstract This study was performed to investigate the effects of different oils in the diets of laying quail on their performance, egg quality, serum lipids and fatty acid composition of egg yolk. One hundred and ninety two 12-wk old Japanese quail were allocated to eight groups with two replicates containing 12 qua...

Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...

Electrical energy is the paramount need in a nation’s development. To cater for large demand for electricity there is a need for reliable and proficient power system. For a power system to work reliably, the role of Transformers is critical. Health of the transformer mainly depends on its insulation. Among the different insulating material used in transformers, mineral oil is the most widely us...

Jatropha curcas has a variety of uses which are of great economic significance. Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to overcome the source limitation problem. In this study, conventional, ultrasound assisted and microwave pretreatment solid liquid extraction of Jatropha seed were studied in terms of amount and quality of the extracted oil. The ...

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...
