The One Chip Challenge is known for using extremely spicy peppers, specifically the Carolina Reaper and the Scorpion Pepper. These peppers are among the hottest in the world.
The challenge itself involves eating just one of these intensely spicy chips and can be quite a daunting task even for those who enjoy spicy foods. The Carolina Reaper alone can register between 1.5 million to 2.2 million Scoville Heat Units (SHU), while the Scorpion Pepper ranges between 1.2 million to 2 million SHU.
Therefore, the One Chip Challenge 2023 chip is likely to be within this range, possibly hitting up to 2.2 million SHU due to the peppers used. The Scoville Scale measures the spiciness of peppers based on the concentration of capsaicin, the chemical responsible for the heat.
When you consume such a spicy chip, capsaicin binds to the TrpV1 receptor in your taste receptor cells. This receptor is typically responsible for detecting heat and sending signals to the brain that indicate something is hot.
