Observations of background residues in animal fats

Chemistry of archaeological animal fats.

Animal fats are preserved at archaeological sites in association with unglazed pottery, human and animal remains, and other deposits or hoards. High-temperature gas chromatography (HT-GC) and combined HT-GC/mass spectrometry (HT-GC/MS) has confirmed the presence of animal fats in lipid extracts of artifacts. Degradation products and pathways have been discerned through the analyses of archaeolo...

Acid 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...

Review: Use of Animal Fats in Aquaculture Feeds

Formulated aquaculture feeds are among the most expensive animal feeds on the market. These feeds are often high in lipids, the bulk of which is generally provided by fish oil. Because of its high cost and potential long-term supply problems, it is now widely acknowledged that fish oil should be used more sparingly in aquafeeds. Rendered animal fats are economical lipid sources that have been u...
