・This is a food additive formulation in which citric acid is coated with calcium citrate.
・Reactions with other substances can be suppressed, which helps maintain quality.
・Its hygroscopic property is lower than that of citric acid, and it is easy to handle
→Since it can prevent the bag from swelling due to reaction with other raw materials, it is widely used in powdered beverages and food applications.
[Solubility in Water]
Oil and fat coated products float on the water surface without dissolving, while Citric Acid CI dissolves in water.
Water solubility
(1% aqueous solution, room temperature,
30 seconds after start of dissolution)
[Inhibition of reaction with sodium bicarbonate]
It was mixed with baking soda at 1:1 and reacted at a temperature of 40 ° C and a humidity of 60% for 19 hours.
Compared with citric acid (anhydrous), Citric Acid CI was able to suppress gas evolution and reduce bag swelling.
Inhibition of reaction with sodium bicarbonate
(temperature 40°C, humidity 60%, 19 hours)
[Inhibition of reaction with vitamin C]
Mixed with vitamin C at 1:1 and allowed to react for 11 days at a temperature of 40°C and a humidity of 75%.
Compared with citric acid, Citric Acid CI exhibited pale coloration and suppressed reaction.
Inhibition of reaction with vitamin C
(Temperature: 40℃, humidity: 75%, 11 days)
[Inhibition of reaction with disodium succinate]
With disodium succinate at 1:1 and at room temperature
Stored for 1 hour and transferred to a petri dish.
Citric acid quickly absorbed moisture, while Citric Acid CI could suppress moisture absorption.
