1. Global context
Energy-efficient, using only water and electricity, with no chemical additives or release of free radicals, this "gentle technique" has a lot going for it in the age of ecology and sustainable development.
However, several decades after the first high-pressure-treated products appeared in Japan, the market share won by this technology remains very modest, with regular development representing around 15 new industrial installations per year. In 2007, there were 115 high-pressure plants in 60 factories producing more than 150 different products, with a total output of around 150,000 t per year, essentially designed to "pasteurize" foodstuffs, i.e. inactivate vegetative microbial forms while preserving the functional properties of the food.
The United States accounts for over half of all installations worldwide. Europe is developing more slowly,...

Regulations

Legislation on the use of high pressure in the food industry.
In Europe, since 1997, EC directive 258/97, known as the "Novel Food" law, has made the marketing of products using new processes subject to prior approval by the European Commission.
To date, only high-pressure fruit processing has been validated (2001/424/EC). However, a simplified procedure (art. 5)...

Economic data
In view of the technologies and materials used, and in the face of reduced productivity, the high-pressure process is still costly, despite the constant evolution of techniques.
An example of the cost calculation for a 300 L batch chamber processing a 600 MPa, 7.5 min packaged product is given in table
