On the other hand, other compounds are irreversibly changed with HPP. Gelatinization of
carbohydrates can be achieved through pressure increase rather than through temperature increase,
and proteins can be denatured at elevated pressures without increasing the temperature. Figure 3
illustrates this pressure-temperature relationship. Although the egg depicted in Figure 3 has visual
similarities to a thermally-processed hardboiled egg, the taste of the pressure-treated egg is actually
closer to that of a raw egg, as temperature-induced flavor changes (chemical reactions) did not
occur during HPP. This presents interesting possibilities from a product development standpoint.
