Meat products contain both saturated and unsaturated fats. Although unsaturated fats are conventionally regarded as 'healthier' than saturated fats, [6] the United States Food and Drug Administration (FDA) recommendation stated that the amount of unsaturated fat consumed should not exceed 30% of one's daily caloric intake. [7] Most foods ...
Animal fats are lipids derived from animals which are used by the animal for a multitude of functions, or can be used by humans for dietary, sanitary, and cosmetic purposes. Depending on the temperature of the fat, it can change between a solid state and a liquid ( oil ) state.
Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double ...
Oleic acid has 18 carbons, is found in most animal fats and olive oil, and is a cis-9-monounsaturated fatty acid. C 17 H 33 CO 2 H, IUPAC organization name (Z)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 13.4 °C, specific gravity 0.891. CAS Registry Number 112-80-1.
Monounsaturated fats are found in animal flesh such as red meat, whole milk products, nuts, and high fat fruits such as olives and avocados. Algal oil is about 92% monounsaturated fat. Olive oil is about 75% monounsaturated fat. [10] The high oleic variety sunflower oil contains at least 70% monounsaturated fat. [11]
For example, even though meat is held under refrigeration or in a frozen state, the poly-unsaturated fat will continue to oxidize and slowly become rancid. The fat oxidation process, potentially resulting in rancidity, begins immediately after the animal is slaughtered and the muscle, intra-muscular, inter-muscular and surface fat becomes ...
According to a 2018 BBC report, researchers who analysed more than 1,000 raw foods, ranked pork fat as the 8th-most nutritious food and gave it a nutritional score of 74. The researchers explained that pig fat was a good source of B vitamins and minerals, and contained more unsaturated fats than lamb or beef fat. [1] [2]
