Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.

A historical (1921) high-pressure steel reactor for the production of ammonia via the Haber process is displayed at the Karlsruhe Institute of Technology, Germany Combined with the energy needed to produce hydrogen and purified atmospheric nitrogen, ammonia production is energy-intensive, accounting for 1% to 2% of global energy consumption , 3 ...
operate at high pressure (on the order of 20 MPa [48]); implement one or more catalysts [49] to accelerate the synthesis of ammonia; operate at a high temperature (between 500 °C and 600 °C) to obtain the best efficiency in the presence of the catalyst; since about 5% of the N 2 and H 2 molecules react with each passage in the chemical reactor:
Fritz Haber (German: [ˈfʁɪt͡s ˈhaːbɐ] ⓘ; 9 December 1868 – 29 January 1934) was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas.
On January 16, Gustafson introduced bill SF 188, which aims to pressure food manufacturers to reduce their use and levels of phthalate chemicals — plasticizers used to make plastics more ...
High-pressure chemistry is concerned with those chemical processes that are carried out under high pressure – pressures in the thousands of bars (100 kPa) or higher.High-pressure processes are generally faster and have a higher conversion efficiency than processes at ambient pressure.
Generally, however, these guidelines agree that highly processed foods contain high amounts of total and added sugars, fats, and/or salt, low amounts of dietary fiber, use industrial ingredients ...
Food containers and cookware are leaching more potentially hazardous chemicals into our bodies than previously thought, new research suggests.
