Proteases (papain, bromelain, ficin) (E1101)

Proteases (papain, bromelain, ficin) are the additives the food industry lists as E1101. In our table they are no risk identified: they take no points off a product's score.

In short
  • The key finding, from EFSA: 'the Panel concluded that there is no concern for genotoxicity of the food enzyme papain'; 'the food enzyme papain extracted from the latex of the unripe C. papaya L. does not give rise to safety concerns under the intended conditions of use'; and 'a risk of allergic reactions upon dietary exposure to this food enzyme, particularly for papaya, ananas, kiwi, soy, fig and pollen allergic individuals, cannot be excluded' (10.2903/j.efsa.2026.9837 (EFSA Journal 2026;24(1):9837, Safety evaluation of the food enzyme papain from the latex of Carica papaya L.))
  • No child flag. The class, and the points it costs, are the same for a child of any age.
  • Where you meet it. They turn up in 1 of the 10,000 packaged foods scanned most on Open Food Facts. Nine in ten of those foods are sold in Europe (counted 26 Sep 2026).
  • 3 citations from EFSA, EU law and the FDA, each one below.

What Proteases do to a score

A packaged food's additive subscore starts at 100 and loses points for each additive on the label; that subscore is a third of the final score. Proteases take no points off a product's score. Scan the pack in Sito and the score you get is the one for your own child's age, with this additive named in the reasons. How we score has the whole method.

See what is in your own cupboard

Scan a packaged food and Sito names the additives in it, then scores the product out of 100 for your child's age.

What the sources found

Every classification in our table comes from the citations below, and nothing else. Each finding is our one-line summary of what the source concluded, with the source and reference beside it.

Why this class

Clean current EFSA and FDA status. These rows exist so that an unfamiliar additive is never treated as a bad one: a missing row costs a product nothing, and a clean row says so with citations.

Our confidence in this row's classification is high. Medium or low does not mean the evidence is weak; it means something about the row is still being pinned down, usually a regulatory status confirmed from one source rather than two.

Questions parents ask

Are Proteases (E1101) safe for kids?

No risk identified. No regulator finding we score, so a product keeps its full additive subscore in Sito. The current status is clean: 'the Panel concluded that there is no concern for genotoxicity of the food enzyme papain'; 'the food enzyme papain extracted from the latex of the unripe C. papaya L. does not give rise to safety concerns under the intended conditions of use'; and 'a risk of allergic reactions upon dietary exposure to this food enzyme, particularly for papaya, ananas, kiwi, soy, fig and pollen allergic individuals, cannot be excluded' (EFSA, 10.2903/j.efsa.2026.9837 (EFSA Journal 2026;24(1):9837, Safety evaluation of the food enzyme papain from the latex of Carica papaya L.)).
