What research says

Animal and lab studies only

  • Open question

    Daily intake limits6

    In animal studies, experts set a daily intake limit for potassium sorbate and sorbic acid.

  • Concern

    blood cell DNA damage7

    In lab studies, potassium sorbate damaged DNA in human blood cells, but it is unclear if this happens in people.

  • Concern

    Cell damage from mixing additives8

    In lab studies, potassium sorbate with aspartame showed more cell damage signs than either alone.

  • Concern

    Liver cell genes10

    In lab studies, potassium sorbate changed how liver cells switch certain genes on and off.

Study type not stated

  • Concern

    Preservative levels in everyday foods3

    In one cake sample, potassium sorbate was above the limit, and its combined risk measure for several foods was above one.

  • No harm found

    Preservatives in drinks5

    Potassium sorbate and sodium benzoate in soft drinks, energy drinks and juices stayed within limits, with no safety risk found for consumers.

How it’s made and used

  • Preservatives in a yogurt drink4

    Potassium sorbate levels in doogh stayed within international limits and below the daily intake considered acceptable.

  • Mold growth on sausages9

    In lab studies, potassium sorbate slowed mold growth, but methyl p-hydroxybenzoate worked better on most molds tested.

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.
