Its specific function as a food additive is currently classified as unknown, and it has not been recognized as Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA). ## Regulatory status | Country | Status | | --- | --- | | United States | approved | | European Union | not_evaluated | | United Kingdom | not_evaluated | | Canada | not_evaluated | | Australia | not_evaluated | | Japan | not_evaluated | | South Korea | not_evaluated | | Brazil | not_evaluated | | China | not_evaluated | | India | not_evaluated | ## Detailed analysis ## What is Corn Endosperm Oil? Corn Endosperm Oil, identified by CAS Number 977010-50-6, is a fatty substance extracted or derived from the endosperm of corn (Zea mays) kernels. The endosperm is the starchy part of the corn kernel that serves as a food source for the germinating plant and is a primary component used in the production of corn flour, grits, and various corn-based products. While corn oil, in general, is a widely used edible vegetable oil primarily extracted from the germ of the corn kernel, Corn Endosperm Oil specifically refers to an oil fraction or extract originating from the endosperm. The precise chemical composition of Corn Endosperm Oil may vary depending on the extraction methods and the specific part of the endosperm utilized, but like other vegetable oils, it would consist primarily of triglycerides, which are esters of glycerol and fatty acids. ## Common Uses As of the current available information, the specific function and common uses of Corn Endosperm Oil (CAS 977010-50-6) as a direct food additive are classified as "unknown." There is no widely documented or established primary use for this specific oil fraction in general food production or as a defined functional additive in commercially available food products. This classification suggests that it may not be in widespread use, or its application is not clearly defined in public regulatory or scientific databases. It is important to distinguish this specific substance from conventional corn oil, which is broadly used as a cooking oil, in margarines, dressings, and many processed foods due to its fatty acid profile and neutral flavor. ## Safety Assessment For Corn Endosperm Oil, a comprehensive safety assessment specifically addressing its use as a food additive is not readily available in public databases. The U.S. Food and Drug Administration (FDA) has not granted it Generally Recognized As Safe (GRAS) status, which means it has not met the criteria for general recognition of safety based on scientific procedures or through experience based on common use in food prior to 1958. A lack of GRAS status does not inherently indicate danger, but it means that the substance would require premarket approval through a food additive petition if intended for use in food. The available data indicates zero reported adverse events to the FDA and zero recalls associated with Corn Endosperm Oil. While the absence of reported adverse events and recalls is a positive indicator, it does not substitute for a formal safety evaluation, especially given its unknown function and presumed limited or non-existent use as a distinct food additive. Without specific studies on toxicology, absorption, metabolism, and potential allergenicity directly related to Corn Endosperm Oil as an additive, a definitive safety profile cannot be fully established. General considerations for any novel food ingredient include potential allergic reactions, dose-dependent toxicity, and long-term health effects. ## Regulatory Status In the United States, Corn Endosperm Oil (CAS 977010-50-6) is not listed as Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA). This means that if it were to be intentionally added to food, it would typically require premarket approval by the FDA through a food additive petition process, demonstrating its safety for its intended use. The "Category: other" classification indicates that it does not fit neatly into common additive categories like preservatives, emulsifiers, or sweeteners, further emphasizing its less defined role in the food industry. There are no records of adverse events or recalls specifically linked to Corn Endosperm Oil in the FDA's databases. Information regarding its regulatory status or assessment by other major food safety authorities, such as the European Food Safety Authority (EFSA), is not publicly available or widely documented, suggesting it has not undergone specific evaluation by these bodies as a distinct food additive. ## Key Studies Publicly available scientific literature and regulatory databases do not contain readily accessible key studies specifically evaluating the safety, toxicology, or functional properties of Corn Endosperm Oil (CAS 977010-50-6) as a food additive. Given its classification with an "Unknown" function and lack of GRAS status, it is unlikely that extensive research focused on its application and safety as a deliberate food ingredient has been widely published or submitted to regulatory bodies for public access. Research on corn components generally exists, but studies that isolate and specifically assess the endosperm oil as a distinct additive are not prominent. For any substance intended for use in food, comprehensive toxicological studies, including acute, subchronic, and chronic toxicity assessments, as well as genotoxicity, allergenicity, and reproductive toxicity studies, are typically required for a thorough safety evaluation. Without such studies, specific conclusions regarding its safety profile as a food additive cannot be drawn. ## Sources - FDA Substances Added to Food (CFSAN) - OpenFDA Adverse Event Reporting System (AERS) - OpenFDA Food Recalls - EFSA OpenFoodTox - EU Food Additive Portal ## Citation Additive Facts.
