When Brazil nuts are used as an ingredient in, for example,
cakes, the (crushed) nuts are usually mixed with the dough and
distributed over the whole food product. The baking of such products
generally implies heating temperatures ranging from 180 C
to 230 C. Despite these relatively high temperatures, due to the
water content in the crumb of these products, the temperature
inside these crumbs will not exceed 100 C. As a result, Ber e 1 situated
only at the outside of a food product can possibly denature
during heat processing. The majority of Ber e 1, however, will be
present in the crumb of the products, where the lower temperature
will not induce the protein to denature.
