In conclusion, in aqueous solutions with pH values between 5.0
and 7.0, a temperature exceeding 110 C is needed to denature Ber
e 1. The denaturation temperature of Ber e 1 in Brazil nuts could,
because of the low water content, is even higher than the temperature
measured (Gekko & Timasheff, 1981). When using common
heat processing methods, the largest part of foods normally do
not reach temperatures > 100 C. This implies that Ber e 1 will
always be consumed (mainly) in its native structure, having an
intact immunodominant conformational epitope, and a high stability
to pepsin digestion (Moreno et al., 2005). As a result, common
heat processing techniques are not likely to affect the digestibility
of Brazil nuts and its concomitant IgE binding capacity after
digestion.
