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.

Urea plant using ammonium carbamate briquettes, Fixed Nitrogen Research Laboratory, ca. 1930 Carl Bosch, 1927. The Bosch–Meiser process is an industrial process, which was patented in 1922 [1] and named after its discoverers, the German chemists Carl Bosch and Wilhelm Meiser [2] for the large-scale manufacturing of urea, a valuable nitrogenous chemical.
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.
The history of the Haber process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical fixation of atmospheric dinitrogen in the form of ammonia, which in turn allows for the industrial synthesis of various explosives and nitrogen fertilizers, and is probably the most important industrial process developed during the twentieth ...
Friedrich Karl Rudolf Bergius (German pronunciation: [ˈfʁiːdʁɪç ˈbɛʁɡi̯ʊs] ⓘ, 11 October 1884 – 30 March 1949) was a German chemist known for the Bergius process for producing synthetic fuel from coal, Nobel Prize in Chemistry (1931, together with Carl Bosch) in recognition of contributions to the invention and development of chemical high-pressure methods.
The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of high-volatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of high-pressure chemistry. [1]
CR also detected bisphenols—chemicals used in reusable food and beverage containers, reusable water bottles, the linings of food cans, and other products—in 79% of the products it sampled.
The chemical industry in Germany is one of the most well-established in the world, and a world leader; a quarter of the chemicals made in the EU, are made in Germany. Currently the German industry, turning over 160 billion euros [ 1 ] is the European leader, and the third-biggest in the world.
