Differentiation of lard, chicken fat, beef fat and mutton fat by GCMS and EA-IRMS techniques.
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...
متن کاملDifferentiation of animal fats from different origins: use of polymorphic features detected by Raman spectroscopy.
Food safety requires the development of reliable techniques that ensure the origin of animal fats. In the present work, we try to verify the efficacy of using the polymorphic features of fats for discriminating animal-fat origins. We use Raman spectroscopy to collect the structural information of fat crystals. It is shown that a single Raman band at 1417 cm(-1) successfully differentiates pork ...
متن کاملPRODUCTION AND CHARACTERIZATION OF MONOCLONAL ANTIBODIES TO CLOSTRIDIUM PERFRINGENS ENTEROTOXIN DERIVED FROM DIFFERENT ANIMAL SPECIES
The enterotoxins (ETs) of Clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. The ETs from alpaca, pig, and calf isolates were chromatographed on Sephadex G-lOO. Monoclonal antibodies (MAbs) against ETs derived from alpaca, pig, and calf C. perfringens isolates were produced. The MAbs were used...
متن کاملAcid and Base Catalyzed Transesterification of Animal Fats to Biodiesel
The present study has been focused on the acid and base transesterification of animal fats (dairy cow and beef) to produce biodiesel by varying process parameters such as catalyst amount, catalyst nature, reaction time and temperature. The maximum biodiesel yield after acid catalysis was 94.1 ± 2.43 and 98.4 ± 2.3 percent for dairy cow and beef t...
متن کاملCharacterization of Salmonellae isolated from different animal and human sources by PCR and resistance trends
Salmonella is one of the most important zoonotic pathogens with many virulence factors playing a major role in its pathogenesis. The aims of this study were to detect spvA, int2 and invC virulence genes of different Salmonella serotypes isolated from various clinical animal and human sources, and to investigate antibiotic resistance patterns among these serotypes. Using a PCR assay, a total of ...
