Thiamin, riboflavin, and ascorbic acid in pre-prepared foods sampled from a hospital food service line decreased slightly during a one and one-half hour serving period and differed somewhat according to month of sampling. On a per serving basis, entrée foods supplied 4% to 17% of the RDA for thiamin and 12% to 18% of the RDA for riboflavin for adult men and women. Potato dishes and fruit gelatins furnished 12% to 26% of the RDA for ascorbic acid, but salads were negligible sources. The data suggest a need to furnish additional sources of these vitamins.
