Vitamin C: Dipping fruit into a solution of crushed Vitamin C tablets and water can prevent oxidation. This is because the vitamin is an antioxidant, which protects the cells of the fruit from free radicals, which cause them to age (the same goes for our skin – which is why it’s so important to include antioxidants in your diet). Cut the fruit/vegetables into slices first so the liquid penetrates the cells adequately.
Ascorbic Acid: Sold as a commercial product, this can be added to water to create an anti-browning solution. Ascorbic acid is a natural property in many citrus fruits, such as oranges and lemons. … it is literally just Vitamin C.
