Abstract
The invention relates to a method for obtaining a product in the form of deep-frozen granules, particles of beads having a high dissolved-gas content from a liquid, semi-liquid or paste-like matrix, that comprises two subsequent steps: a matrix gasification step that comprises the incorporation of gas at a pressure higher than 2 bars; and a quick deep-freezing step using a cryogenic fluid.
Claims15
A method for obtaining a product in a form of deep-frozen granules, particles or beads, which are rich in dissolved gas, starting from a liquid, semi-liquid or pasty matrix, said method comprising two consecutive steps:
- a gasification step of the matrix by incorporating gas under a pressure of more than 2 bar,
- a rapid deep-freezing step by cryogenic fluid.
