Ascorbic Acid is a White crystals Crystalline Powder,also named Vitamin C
Ascorbic acid is commonly used as a food additive in the food industry. It is used as a preservative, antioxidant, and nutrient fortifier.
As a preservative, ascorbic acid helps to extend the shelf life of food products by inhibiting the growth of bacteria, yeast, and mold. This is especially useful in preventing spoilage in products such as fruit juices, canned fruits, and vegetables.
As an antioxidant, ascorbic acid helps to protect food from oxidative damage caused by exposure to air, light, and heat. This is important in preventing the breakdown of food products and the loss of their nutritional value.
As a nutrient fortifier, ascorbic acid is added to many processed foods to increase their nutritional value. This is especially important in products such as breakfast cereals and fruit juices, which are often low in vitamin C.
The use of ascorbic acid as a food additive is generally considered safe when used within the limits set by regulatory agencies. However, some people may be sensitive to high doses of ascorbic acid, and excessive consumption can cause gastrointestinal problems. Therefore, it is important to follow the recommended daily intake and to read food labels carefully to avoid overconsumption of ascorbic acid.
