Orangegg was prepared by adding thawed orange juice to blended fresh whole egg; it was then stored at 4 C. Without additional treatment, orangegg developed an undesirable flavor after 2 days of storage. With the addition of the antioxidant Tenox 2 (to give 200 ppm BHA), the drink remained palatable and free of the off-flavor after 14 days storage.Gas-liquid chromatographic (GLC) analysis of volatile materials in the untreated stored orangegg by the headspace gas-sampling method showed that increases in n-pentanal and n-hexanal paralleled the development of the off-flavor. Tenox, added to orangegg, controlled the oxidation, so that there was virtually no increase in these aldehydes during storage. (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
