Quick and Easy: Using Light to Measure Hotpot Spice

Do you love spicy hotpot? Ever wondered why some hotpots are super spicy while others are just mildly hot? The answer lies in the levels of capsaicin (CAP) and hydroxy-α-sanshool (α-SOH). These compounds make the hotpot spicy and numbing, respectively. Traditionally, scientists use liquid chromatography to measure these compounds, but this method requires destroying the sample. Oops, that's not handy for chefs, right? So, scientists explored a new way using light called hyperspectral imaging (HSI).They combined HSI with machine learning to create a model that can predict the levels of CAP and α-SOH without harming the hotpot seasoning. Guess what? It worked like a charm! They found specific wavelengths of light that can help identify these compounds quickly and accurately. Isn't that cool? Imagine being able to assess the spiciness of your hotpot just by looking at it! This method could revolutionize how we understand and control the flavors in our food.
