despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

polycyclic aromatic hydrocarbons (pahs) are a class of complex substances that are produced during incomplete combustion of fossil fuels. pahs are known to be persistent pollutants which can remain in nature for years. in 1991 during the first persian gulf war south west part of iran was contaminated heavily. this study was undertaken to see if the pahs can be traceable in animal tissues many y...

Animal waste fats were explored as a fermentation substrate for the production of high-value unsaturated single cell oil (SCO) using oleaginous fungi, Mucor circinelloides and Mortierella alpina. Both strains showed good growth lipid accumulation when animal fat carbon source. The biomass concentration 16.7 ± 2.2 gDCW/L content 54.1%wt (of dry weight) obtained in shake flask experiments, surpas...

Results Decreased turnover of fat cells and their lipid contents is associated with insulin resistance, dyslipidemia and altered metabolic function of fat cells. Low fat cell turnover leads to adipose hypertrophy which is linked to insulin resistance in subcutaneous fat and to dyslipidemia in visceral fat. A transcription factor (EBF-1) regulates hyperplasia/hypertrophy in human adipose tissue ...

Detection of animal mixtures in meatballs by using Fourier Transform Infrared Spectroscopy (FTIR spectroscopy) has been studied. This research aims to study the different markers fat characters containing mixture chicken fat, lard and rat fat. Sample preparation used Soxhlet extraction with n-hexane solvent distillation from solvent. The temperature is 70°C volume 200 mL. Fat samples were prepa...

This study produced fish mortadella from Mechanically Separated Meat (MSM) of Nile tilapia added with animal fat. Three formulations were developed: M1 (MSM - 89 % and 5 pork fat), M2 84 10 fat) M3 79 15 fat). The elaborated products tested for technological, physical, physico-chemical, microbiological sensory parameters. results showed that the microbiologically stable a particular texture an ...

A study was conducted to differentiate lard, chicken fat, beef fat and mutton fat using Gas Chromatography Mass Spectrometry (GC-MS) and Elemental Analyzer-Isotope Ratio Mass Spectrometry (EA-IRMS). The comparison of overall fatty acid data showed that lard and chicken fat share common characteristics by having palmitic, oleic and linoleic acid as major fatty acids while beef and mutton fats sh...
