Question

Quizplus · Accepted Answer

Recent research has shown that there are at least five primary tastes (sweet, sour, bitter, salty, and umami) and that many tastes cannot be created from combinations of the primaries. This challenges the traditional four-taste component processing theory, which suggested that all tastes can be perceived by a combination of sweet, sour, bitter, and salty. However, there are receptors for bitter and sweet, so option A is incorrect. Therefore, the correct answer is E, as it accurately reflects the limitations of the conventional four-taste component processing theory of taste.
