PURPOSE: To provide the subject inexpensive salt excellent in nutrition by regenerating an ion exchange resin used in desalting whey with hydrochloric acid and caustic soda, concentrating, drying and powdering the regenerated solution of minerals, hydrochloric acid and caustic soda obtained therein.
CONSTITUTION: A whey liquid formed as a by-product in producing cheese and casein in a prescribed amount is passed through a cation and anion exchange resins to adsorb minerals in the whey and desalt the whey. A hydrochloric acid solution is then passed through the cation exchange resin through which the above-mentioned whey is passed and a caustic soda solution is subsequently passed through the anion exchange resin for regeneration. The solution containing the minerals and hydrochloric acid and solution containing the minerals and caustic soda obtained by the afore-mentioned regeneration are mixed, further concentrated using a concentrator, etc., and, as necessary, dried and powdered with a rotary type dryer, etc., to afford the objective substitute salt excellent both in salty taste and in flavor.
