Considering the possibility of the harmful side effects of synthetic antioxidants, it is necessary to substitute the synthetic antioxidants by the natural ones, the antioxidants that have been consumed by man for years. The mango seeds were washed and air dried and the kernels were removed manually from the seeds. Mango seed kernel oil was extracted by hexane using soxhlet extraction apparatus....

Based on evidence from rodent models, it was hypothesized that furan fatty acids found in corn would inhibit reproduction in the laying hen. An isomeric mixture of furan fatty acids [9, (12)-oxy-10,13-dihydroxystearic acid and 10, (13)-oxy-9,12-dihydroxystearic acid] was administered for a period of 3 wk via the diet (1 and 3 ppm) at levels greater than those in corn to 20-wk-old pullets. There...

Some poultry processing operations remove harmful microbes from the carcass of broiler chickens during processing, but other processing operations can cause further contamination. Although commercial poultry processors use chemical sanitizers to reduce microbial contamination during processing, poultry is still recognized as a major cause of human foodborne diseases. Some naturally occurring fa...

It has been reported that dietary polyunsaturated fats (PUFA) increase liver injury in response to ethanol feeding. We tested the hypothesis that diets rich in linoleic acid (18:2n-6) would affect acute liver injury after acetaminophen injection and that protein restriction might exacerbate the liver injury. We examined effects of feeding diets with either 15% (wt/wt) corn oil or 14% beef tallo...

Consumers are more and more interested in the health aspects of their food. Therefore, it is essential for poultry meat production to be aware of factors affecting poultry meat quality. Furthermore, changes in consumption features and the increasing interest of consumers in value for money products have to be considered. Nutrients in poultry meat may be divided into classes with positive (impro...

Fats and oils are chemically diverse group of compounds, which have the highest energy density among all macro nutrients. Besides having high caloric values, they are major sources of essential fatty acids (Ω-3 and Ω-6), fat soluble vitamins (A, D, E and K) and lecithin. Moreover, supplementation of fats and oils to poultry rations increases the metabolizable energy of the total ration, the cal...

The chemical composition variations of the Indian mackerel (Rastrelliger kanagurta) from Karachi coast were investigated seasonally over the period of one year (2004-2005).  Moisture, crude protein, fat and ash contents varied from 70.11-74.41%, 16.02- 20.09%, 3.0-12%, and 0.89-1.35% respectively. The seasonal data indicated that the main fatty acids of the total lipid were C16:0, C16:1, C18:0,...

ABSTRACT: Olives belong to the family of olea europaea L. is a popular fruit tree. The fruit and the oil extracted from it is consumed worldwide particularly in the Mediterranean regions. In this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. This work is concerned with the best harvesting point when oleic acid ...

enzymatic acidolysis of canola oil through caprylic and capric acids was investigated for making structured lipids. lipozyme tl im, an sn-1,3 specific thermomyce slanuginosa lipase, was utilized as the biocatalyst in the batch reactor. reaction conditions were designed according to taguchi’s method considering fatty acid to oil ratio, at three levels (1:1, 2:1, 3:1) , enzyme load (4, 8 and, 12%...
