What research says
How it’s made and used
-
Mouth feel of food3
In lab studies, sodium carbonates reduced how green tea flavanols stick to salivary proteins.
-
Shrimp cooking yield4
In shrimp, soaking in sodium carbonates increased weight and cooking yield and reduced cooking loss as pH rose.
The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
