Method for producing a saturated sodium chloride solution, useful particularly for seasoning foods, includes treating the initially formed solution to improve its properties and remove impurities

摘要

Method for producing a liquid salt (A) that comprises mixing a solid salt (B) with water to give a saturated solution (SS) of NaCl, then subjecting this to a series of processes to improve its characteristics and to eliminate impurities. This series includes at least (i) modifiying the pH of SS, or of mother solution, to a level at which flocculants (F) can interact with colloidal particles and suspended impurities, characteristic of (B); and (ii) treatment with F. Independent claims are included for the following: (1) (A) prepared by the new method; (2) solid salt (B') obtained from (A) by evaporation and crystallization of a mixture of (A) plus agglomerants; and (3) system for preparing (A).
