Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).
Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C). [1] [2] [3] The FSIS stipulates that potentially hazardous food should not be stored at temperatures in this range in order to prevent foodborne illness [a] and that food that remains in this ...
Supercritical fluids have found application in a variety of fields, ranging from the extraction of floral fragrance from flowers to applications in food science such as creating decaffeinated coffee, functional food ingredients, pharmaceuticals, cosmetics, polymers, powders, bio- and functional materials, nano-systems, natural products ...
In addition, hot food must be held at a minimum interval of 135 °F (57 °C) if it is not immediately consumed. The temperature must be checked every 4 hours or else labeled with a discard time. Although monitored hot food can be held indefinitely in this way without a food safety concern, the nutritional value, flavor, and quality can suffer ...
Food protection is the umbrella term encompassing both food defense and food safety. These six terms are often conflated. Along with protecting the food system , food defense also deals with prevention, protection, mitigation, response and recovery from intentional acts of adulteration.
supercritical gas-liquid boundaries in pT diagram. According to textbook knowledge, it is possible to transform a liquid continuously into a gas, without undergoing a phase transition, by heating and compressing strongly enough to go around the critical point.

Supercritical carbon dioxide can be used as a solvent in dry cleaning. [4] Supercritical carbon dioxide is used as the extraction solvent for creation of essential oils and other herbal distillates. [5] Its main advantages over solvents such as hexane and acetone in this process are that it is non-flammable and does not leave toxic residue.
