This value is then converted into Scoville heat units using a conversion factor. The amount of capsaicinoids in the sample is then calculated based on the area under the curve of the capsaicinoid peak. A UV detector is used to detect and quantify the capsaicinoids. The extract is then injected into the HPLC column, where the capsaicinoids are separated based on their chemical properties. To measure capsaicinoid concentration using HPLC, a sample of the pepper is first extracted with a solvent, typically acetonitrile. The separated components are then detected and quantified by a detector. It works by passing a liquid sample through a stationary phase that separates the individual components based on their chemical properties. HPLC is a technique that can separate and quantify individual components of a sample. Measuring SHUs with HPLCĬapsaicinoids are the compounds that give peppers their spiciness. High-Performance Liquid Chromatography (HPLC) is one of the most commonly used methods to measure capsaicinoid concentration and calculate Scoville heat units (SHUs). The Scoville scale is used to measure the spiciness of food, and it is based on the concentration of capsaicinoids in a particular food item. However, for some, it can be a painful and uncomfortable experience. Measuring Scoville Heat Units (SHUs) with HPLCįor many people, the spiciness of food is a source of pleasure and enjoyment. It also required smaller samples and provided a more reliable way of measuring the spiciness of peppers. This method was more precise, accurate, and objective compared to the previous method. In the 1980s, a new method for measuring SHUs was developed using High-Performance Liquid Chromatography (HPLC). In addition, it was time-consuming and required a significant amount of pepper samples. It relied on individual taste perception and was prone to errors due to subjectivity. This method, however, had several limitations. The higher the dilution level required, the lower the SHU rating. He used a subjective method in which he tasted diluted pepper extracts and determined the dilution level at which he no longer felt any heat. In 1912, Wilbur Scoville, an American pharmacist, created the Scoville scale to measure the spiciness of peppers. So, the next time you’re trying a new pepper or a new hot sauce, take a look at the Scoville rating and prepare your taste buds accordingly! The Scoville Scale and its History Our Scoville Heatmeter is a helpful guide for understanding the heat levels in peppers and hot sauces. It’s also important to handle hot peppers with care, as capsaicin can cause skin irritation and eye irritation if it comes into contact with these areas. Some people may find a jalapeño pepper too hot, while others can handle a ghost pepper with ease. While the Scoville scale is a useful tool for measuring heat, it’s important to remember that individual tolerance to heat can vary widely. The higher the capsaicin concentration, the higher the Scoville rating. The Scoville scale is determined by measuring the amount of capsaicin in a pepper, which is the compound responsible for the heat. The scale ranges from 0 to 16 million Scoville Heat Units (SHU), with 0 being no heat and 16 million being the maximum heat level. The Scoville scale is a measurement of the heat level in peppers, named after Wilbur Scoville, who developed the test in 1912.
