Lysozyme (E1105): What the Sources Found

Lysozyme is the preservative the food industry lists as E1105. In our table it is no risk identified: it takes no points off a product's score for a child.

In short

No risk identified. No regulator finding we score, so a product keeps all 33 additive points.
No child flag. Nothing below is written about children specifically, so the class is the same at every age.
1 citation from EFSA, each one below.

What Lysozyme does to a score

A packaged food starts with 33 points for what is in its ingredient list. Lysozyme takes 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.

What the sources found

Every classification in our table comes from the citations below, and nothing else. They are quoted as the source wrote them.

EFSA 10.2903/j.efsa.2023.7918 (Safety evaluation of the food enzyme lysozyme from hens' eggs); see also 10.2903/j.efsa.2025.9726
Dietary exposure lower than the corresponding intake from eggs for all population groups; 'the food enzyme lysozyme does not give rise to safety concerns under the intended conditions of use, except for the known adverse allergic reactions that occur in susceptible individuals' — residual lysozyme in treated beers, cheese and wine may trigger allergenic reactions.

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 medium. 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.
