What research says

How it’s made and used

  • Pork quality and cooking2

    Potassium carbonates helped pork keep its red color, lose less juice when cooked, and stay tender.

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.
