Abstract
Some consumers believe that organically grown foods, as compared with conventionally grown foods, are more nutritious. Because orange juice is an excellent source of vitamin C, this study specifically compared the vitamin C concentration of commercially available refrigerated 100% orange juice from organically grown versus conventionally grown oranges. Vitamin C contents of 30 samples (3 different lot numbers from 10 different brands) of pulp-free, not from concentrate 100% orange juice were tested using the Association of Official Analytical Chemists method. Irrespective of expiration dates, there was no difference in vitamin C content of 100% juice from organically grown oranges as compared with conventionally grown oranges. Consumers should keep this in mind when making their purchasing decisions.
