What research says

How it’s made and used

  • Shrimp cooking yield3

    In shrimp, soaking in sodium carbonates increased weight and cooking yield and reduced cooking loss as pH rose.

  • Mouth feel of food4

    In lab studies, sodium carbonates reduced how green tea flavanols stick to salivary proteins.

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 two findings in people. Findings whose study type is not stated are shown but not counted.
