Chicken fat, a source of unsaturated fatty acid, is obtained from cooked poultry by-products. A fat molecule consists of a glycerol and three fatty acids. This work aimed to introduce a novel chemical-biochemical process technology for full exploitation of chicken fat building blocks, that is, conversion of fatty acids to fatty acid calcium salts (FACSs) and utilization of glycerol for cultivation of microalgae (Dunaliella salina). FACSs are fed to cows as rumen-protected fat.Response surface methodology was used for optimization of calcium salt production in pilot scale reactor. A pilot-scale helical photobioreactor was used for cultivation of D. salina. The results pointed out that from each 1,000 g of chicken fat, approximately 840 g of FACS and approximately 39 g of D. salina powder can be obtained. The proposed process technology is a potentially economic alternative for current commercial FACS production processes where glycerol in their waste is not exploited.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
