It was not clear to me whether the degradation products of human chitinase and non-human chitinases are the same, which is why I explicitly specified non-human chitinases. It seems likely to me that people with latex-fruit allergies would also be allergic to the breakdown products from non-human chitinases, whereas those with shellfish and dust mite allergies would also be allergic to the breakdown products from human chitinase. Either way, it is likely to be a food allergen.
