Which statement about allergen proteins is TRUE?
a.Rinsing a plated dish under running water washes the allergen proteins away
b.Freezing a dish overnight breaks the allergen proteins down for good
c.Allergen proteins are not destroyed by normal cooking or freezing
d.Cooking a dish to above 165°F destroys the allergen proteins in it
Giải thích
Unlike most pathogens, allergen proteins are not destroyed by cooking or freezing, so the only reliable protection for an allergic guest is preventing the allergen from contacting the food at all. Rinsing a plate leaves protein behind on the food and the dish, freezing does not break the protein down, and heat above 165°F kills pathogens without changing the allergen — which is why none of those three can make a dish safe once cross-contact has occurred.
