- food products such as milk, creams, beer, fruit juice
- the field of the invention is therefore that of the membrane permeabilization of biological cells and, in particular, the destruction of biological cells by pasteurization.
- Thermal treatments for pasteurization may consist of the use as a heat vector of the following means:
- electromagnetic radiation such as infrared radiation, microwave radiation
- one of the solutions may be to heat food at higher temperatures than the range. above mentioned (for example at temperatures above 90 ° C.).
- higher temperatures are inevitably accompanied by a denaturation of the treated product, such as a denaturation of the proteins present in the product, which does not go often without a loss of taste qualities of the product.
- the invention relates, according to a first object, to a membrane permeabilization process for biological cells contained in a product, said method being implemented in a treatment device comprising at least one treatment chamber emitting a pulsed electric field, said method comprising the following steps:
- a withdrawal step at a predetermined withdrawal rate, the product output of said chamber so as to reroute upstream of said chamber and downstream of said feed unit.
- the process of the invention is an in vitro process for membrane permeabilization of biological cells, that is to say which is carried out with a product lying outside an animal organism.
- the process of the invention makes it possible to obtain a significant increase in cell membrane permeabilization and this with at least one treatment chamber (the increase being quantified in terms of cell death rate) compared to a process comprising one or more passages of the product in the aforementioned chamber without using a withdrawal step as mentioned above and for the same specific energy used.
- the cells treated in the context of the process may be prokaryotic cells, eukaryotic cells, these cells may be alive or dead, whole or partial and of animal or vegetable origin.
- these cells may be derived from unicellular or multicellular organisms, such as bacteria (in particular, eubacteria), fungi (in particular, molds, yeasts (such as Saccharomyces cerevisiae), molds, algae ( in particular, microalgae), viruses and prions.
- bacteria in particular, eubacteria
- fungi in particular, molds, yeasts (such as Saccharomyces cerevisiae), molds, algae ( in particular, microalgae), viruses and prions.

- the cells to be treated are included in a product, which may be a liquid food, such as fruit juice, vegetable juice, milk, water.
- a product comprising said cells may contain tissues, macromolecules, such as biopolymers, organic or inorganic molecules.
- the pulsed electric field to which the product comprising the cells is subjected has the effect of permeabilizing said cells.
- the exposure of a cell to an external electric field induces a difference of electric potential on both sides of the membrane constituting the cell.
- this field is very intense (especially when it is greater than 10,000 V / cm), it can induce a transmembrane potential of higher value than the natural potential of the cell.
- the transmembrane potential reaches a critical value, the electrostatic phenomena between the charged molecules on either side of the membrane cause the formation of pores in the cell membrane thus increasing its permeability.
- pore formation in the cell membrane is irreversible, this may result in outward migration of cell contents and, thus, death of the cell.
- the pulsed electric field as a function of the desired degree of permeabilization, will have the characteristics necessary to obtain this permeabilization in terms of voltage value, number of pulses, signal shape, specific energy delivered by said field.

- the use of electrical pulses makes it possible to minimize the phenomenon of heating of the product by the Joule effect and thus the temperature thereof (typically below 50 ° C.). This makes it possible to avoid the denaturation of components present in the product, which denaturation is conventionally encountered during the implementation of a process involving high temperatures.
- the electrical pulses are delivered within a treatment chamber that may be in the form of an enclosure comprising electrodes that allow the passage of current in the form of electrical pulses. These electrodes can be flat, circular, coaxial, co-linear, rotating or having any other appropriate geometry.

- the product in the treatment chamber, the product, especially when it is in the form of a liquid, can be subjected to a turbulent hydraulic regime.
- This hydraulic mode is particularly advantageous.
- the permeabilization of the cells during an electric discharge is preferentially carried out on the faces of the cell membrane located opposite the electrodes.
- a cell When a cell is in motion (which is the case when the product is subjected to a turbulent regime) disordered with respect to the electrodes and is subjected to a series of pulses, it will suffer scattered impacts, which will contribute to increase the effectiveness of the treatment in terms of permeabilization.
- a cell immobile relative to the electrodes will be subjected to a concentration of impacts, which will reduce the effectiveness of the treatment.
- a withdrawal step downstream of the treatment chamber, of the product treated in the treatment chamber at a predetermined withdrawal rate, of to reroute this product withdrawn upstream of the treatment chamber and downstream of said feed unit, whereby the withdrawn product is introduced again into the treatment chamber and subjected again to the pulsed electric field.
