• The proportion of foods and of non-milk beverages that may contain the food enzyme:
The proportion of solid foods and beverages that may contain the food enzyme is set generally
at 25 %. The default proportion (25 %) of beverages and solid food that could contain the
enzyme was considered adequate. Although xylanase may be used in a variety of solid foods
and beverages that could represent more than 25 % of processed foods, it is unlikely that a
person would systematically choose all processed foods with the same enzyme added even
considering brand loyalty. This assumes that a typical adult weighing 60 kg consumes daily
1.5 L of beverage and 750 g of solid foods containing the food enzyme.
