검증된 단계별 안내1
Identify the basic taste sensations: Sweet, Sour, Salty, Bitter, and Umami.
Understand that 'Umami' is recognized as a basic taste sensation, often described as savory.
Recognize that 'Sweet' is a basic taste sensation associated with sugars and certain proteins.
Acknowledge that 'Sour' is a basic taste sensation typically associated with acidic substances.
Note that 'Spicy' is not a basic taste sensation; it is a sensation of pain or heat caused by compounds like capsaicin, not a taste.
