Q

Describe the common acids used in soft drinks as additives

A

Citric- natural acid
Malic- natrual acid
Phosphoric acid- a stronger acid usually used in cola drinks. Phosphorus is present in most animal and plant cells. Cola drinks contain about 13-19mg/100ml compared to 200-800 mg/100gm in cheese eggs, meat, fish, bread and nuts
