Elaeis than oils made from canola, corn, linseed, soybeans, safflower, and sunflowers, it can withstand extreme deep-frying heat and resists oxidation. It contains no trans fat, and its use in food has increased as food-labelling laws have changed to specify trans fat content. Oil from "Elaeis guineensis" is also used as biofuel. Human use of oil palms may date back to about 5,000 years in coastal west Africa. Palm oil was also discovered in the late 19th century by archaeologists in a tomb at Abydos dating back to 3000 BCE. It is thought that Arab traders brought the oil palm to
Poaching (cooking) periods, as with sous-vide. It is also used to rapidly raise the temperature of foods, as with blanching. Poaching itself is part of a family of moist-heat cooking methods but separates itself in that it is primarily for delicate foods such as eggs. Simmering generally uses a higher temperature for cooking, and because it surrounds the food in water that maintains a more or less constant temperature, simmering cooks food very evenly. Boiling uses the absolute highest temperature for water and is least likely to be used in cooking delicate foods. While it cannot achieve caramelization, which to many is
