Refined poultry fat comprising less than about 300 ppm of minerals and metals, wherein the refined poultry fat is resistant to bacterial growth when challenged with a bacterial species. The refined poultry fat is prepared from rendered poultry fat by a process comprising introducing moisture into the rendered poultry fat product to form a hydrated poultry fat product; (b) agitating and heating the hydrated poultry fat product such that droplets of water are dispersed throughout and coalesce with water-soluble impurities and/or particulate impurities in the hydrated poultry fat product to form a plurality of water-laden particles; and (c) removing the plurality of water-laden particles. The refined poultry fat can be used as an ingredient in the animal food industry, or can be used in the renewable energy industry.
A refined poultry fat product prepared from a rendered poultry fat product, the refined poultry fat product having a moisture content of less than 1% wherein the moisture consists of water, a mineral and metal content of less than 300 ppm, and a free fatty acid content of less than about 6%, wherein when the refined poultry fat product is incubated with Salmonella and bacterial growth is monitored by plate optical density at 590 nm using a multiwell plate reader over a period of about 18 hours the optical density is less than 0.2 indicating essentially no bacterial growth.
A refined poultry fat product comprising less than 300 ppm of minerals and metals, which is prepared from a rendered poultry fat product by a process in which water-soluble impurities and particulate impurities in the rendered poultry fat coalesce with particles of water to form water-laden particles, and the water laden-particles are removed to form the refined poultry fat product.
A refined poultry fat product prepared from a rendered poultry fat product, the refined poultry fat product having a moisture content of less than 1% wherein the moisture consists of water, and a free fatty acid content of less than about 3%, wherein when the refined poultry fat product is incubated with Salmonella and bacterial growth is monitored by plate optical density at 590 nm using a multiwell plate reader over a period of about 18 hours the optical density is less than 0.2 indicating essentially no bacterial growth.
