Chromatography is an important method used in testing food to keep it safe and high-quality. It helps scientists look at different parts of food samples and find out what substances are there. Here are some ways it’s used:
Checking for Pesticides: Chromatography, especially a type called High-Performance Liquid Chromatography (HPLC), can find traces of more than 400 different pesticides in food. Studies show that up to 84% of the fruits and vegetables we buy might have some pesticide leftovers.
Testing Food Additives and Contaminants: Another type called Gas Chromatography (GC) is used to check for artificial colors and preservatives in food. Some food dyes are not allowed by safety rules, and chromatography helps make sure these rules are followed.
Measuring Nutritional Content: Chromatography is also used to measure vitamins and fats in food. For example, HPLC can be used to see how much Vitamin C is in fruits, usually between 10 to 100 mg for every 100 grams.
Finding Flavor and Aroma Compounds: The smells and flavors in food can be studied using a special method with solid-phase microextraction and then GC. Some foods can have hundreds of different smell compounds, and chromatography helps check these to make sure the food is good quality.
In summary, chromatography is very important for keeping our food safe and making sure it meets quality standards, which is essential for protecting our health.
