Vitamins are organic molecules that play important roles in various biochemical reactions within the body. In the food industry, vitamins are used as food additives to improve the nutritional value of products. Vitamin fortification is a common strategy used to address nutrient deficiencies in the population. Innovative vitamin chemistry solutions aim to improve the stability, solubility, and bioavailability of vitamins in food products. The interactions between vitamins and other food ingredients are complex, and the development of effective vitamin solutions requires a deep understanding of food chemistry and nutritional science.
