What is the purpose of using ascorbic acid?

Rating: 100

Ascorbic acid is used as an anti-darkening agent for fruits. Some older recipes may call for ascorbic acid crystals. If you can't find crystalline ascorbic acid, substitute crushed Vitamin C tablets (ascorbic acid). One-half teaspoon of ascorbic acid crystals is equivalent to 1500 mg. of Vitamin C. Crush enough Vitamin C tablets to approximate the quantity required in the recipe.
