The fortification process involves adding synthetic ascorbic acid to the food product during manufacturing. This synthetic form is identical to the natural vitamin C found in fruits and vegetables and is equally effective in providing the necessary nutritional benefits. Fortification levels vary depending on the product and the target population, but they are generally designed to provide a significant portion of the recommended daily intake of vitamin C.
In conclusion, fortified foods such as cereals, juices, and dairy products are an important means of ensuring adequate ascorbic acid intake in various populations. By adding this essential nutrient to commonly consumed foods, manufacturers can help to address potential deficiencies and promote overall health and well-being.
