. Table 2 shows the relative
IC50 values for the almond protein extract were not affected significantly
by dry heat for 10 min at 100 or 200 C (p > 0.05), indicating
that almond proteins are stable under these dry heat conditions.
This is consistent with the results reported previously where amandin was readily detected in almonds that were subjected to
dry heat at temperatures below 200 C (Sathe & Sharma, 2009).
After dry heat for 10 min at 400 C, the sample was unable to bind
with the antibody, consistent with the lower protein recovery
(Table 1). Therefore, dry heat at 400 C might provide a mean to
reduce allergen residues on surfaces and minimize allergen cross
contact during food production.
