Example Embodiment
[0016] Example 1
[0017] Accurately weigh 453.6 g of citric acid and 450.2 g of L-malic acid respectively and place them in the reaction vessel, add 752 g of water, start stirring, then accurately weigh 600 g of calcium carbonate, and slowly add them to the acid solution placed in the reactor to make carbonic acid. Calcium is fully reacted with the acid solutions of citric acid and malic acid, the adding process is 5 minutes, and the solution temperature during the adding process is 20°C to 70°C. Then stop stirring, let stand at room temperature for 30min, so that the citric acid malic acid slurry is crystallized and precipitated, and after drying, 1730 g of calcium citric acid malate product is obtained, the yield is 96.86%,
[0018] The product quality data are:
[0019] Moisture content (w / w%): 8.52%;
[0020] Calcium content (on a dry basis): 20.86%;
[0021] Arsenic content: <0.5mg / kg;
[0022] Lead content: <0.5mg / kg;
[0023] Mouthfeel evaluation: The mouthfeel is...
Example Embodiment
[0025] Embodiment 2
[0026] Accurately weigh 12.608kg of citric acid and 13.404kg of L-malic acid respectively and place it in the reaction vessel, add 132kg of water to make a mixed acid solution, start stirring, then accurately weigh 18kg of calcium carbonate and slowly add it to the acid solution of the reactor , the raw materials in the reactor are fully reacted, the adding process is 20 min, and the solution temperature during the adding process is 20°C to 70°C. Then stop stirring, let stand at room temperature for 100min, so that the citric acid malic acid slurry is crystallized, and after drying, 34.158 kg of calcium citric acid malic acid is obtained, the yield is 95.74%,
[0027] The product quality data are:
[0028] Moisture content (w / w%): 7.86%;
[0029] Calcium content (on a dry basis): 21.15%;
[0030] Arsenic content: <0.5mg / kg;
[0031] Lead content: <0.5mg / kg;
[0032] Mouthfeel evaluation: The mouthfeel is fine, without gritty feeling, and the flavor i...
