Procedure

Process: Heat citric acid and malic acid to 60° C. and moisten with 6 ml of a gluconic acid delta-lactone solution (10 parts of gluconic acid delta-lactone, 5 parts of water). Add sodium bicarbonate I and allow reaction to give monosodium citrate; then allow sodium bicarbonate II to undergo partial reaction (partial conversion to the citrate). Add citric acid powder and cover the surface by partial reaction. Add sodium carbonate and allow to undergo partial reaction and finally dry in vacuo. This effervescent base is mixed with 200 parts of acetylcysteine and with corresponding fillers, aromas and sweeteners.
