What is the shelf life of ascorbic acid in corn syrup?

The shelf life of ascorbic acid in corn syrup can vary depending on storage conditions, but generally, it is stable for about 1 to 2 years when stored in a cool, dark place. Exposure to light, heat, and air can degrade ascorbic acid, reducing its efficacy. Proper sealing and avoiding contamination can help maintain its potency for a longer period. Always check for any signs of degradation, such as changes in color or smell, before use.
