Chemical Stability of Ascorbic Acid Integrated into Commercial Products: A Review on Bioactivity and Delivery Technology

The L-enantiomer of ascorbic acid is commonly known as vitamin C. It is an indispensable nutrient and plays a key role in retaining the physiological process of humans and animals. L-gulonolactone oxidase, the key enzyme for the de novo synthesis of ascorbic acid, is lacking in some mammals including humans. The functionality of ascorbic acid has prompted the development of foods fortified with this vitamin. As a natural antioxidant, it is expected to protect the sensory and nutritional characteristics of the food. It is thus important to know the degradation of ascorbic acid in the food matrix and its interaction with coexisting components. The biggest challenge in the utilization of ascorbic acid is maintaining its stability and improving its delivery to the active site. The review also includes the current strategies for stabilizing ascorbic acid and the commercial applications of ascorbic acid.

Automated summary

The L-enantiomer of ascorbic acid, also known as vitamin C, is essential for maintaining physiological processes in humans and animals. The lack of a key enzyme for de novo synthesis of ascorbic acid in some mammals, including humans, has led to the fortification of foods with this vitamin. Understanding the degradation of ascorbic acid in the food matrix and its interaction with coexisting components is crucial for its stability and delivery to the active site.
