5,7-dihydroxy-2-(3-hydroxy-4-methxy-phenyl)-chroman-4-one

5,7-dihydroxy-2-(3-hydroxy-4-methoxy-phenyl)-chroman-4-one, identified by CAS number 520-33-2, is a naturally occurring flavonoid belonging to the chroman-4-one chemical class. Flavonoids are a group of polyphenolic compounds widely distributed in plants, including fruits, vegetables, and botanicals. This particular compound features a chroman ring structure with multiple hydroxyl groups and a methoxy substituent, which contribute to its chemical and sensory properties.

This flavonoid is utilized in the food industry as a flavoring agent and flavor adjuvant. Due to its natural plant origin and polyphenolic structure, it is incorporated into various food and beverage products to contribute to or enhance flavor complexity. Common applications include flavored beverages, functional foods, and food products where plant-derived flavor compounds are preferred. The compound's use aligns with consumer trends toward natural flavoring ingredients derived from botanical sources rather than synthetic alternatives.

The safety profile of 5,7-dihydroxy-2-(3-hydroxy-4-methoxy-phenyl)-chroman-4-one reflects characteristics typical of naturally occurring flavonoids. According to FDA records, there are zero reported adverse events associated with this additive and zero recalls. The absence of safety incidents in the FDA database indicates no documented harmful effects in the consumer population at reported use levels.

As a flavonoid, this compound is structurally related to numerous plant-derived compounds with established histories of safe consumption. Flavonoids generally have undergone extensive scientific evaluation and are recognized as naturally occurring dietary components. The multiple hydroxyl groups present in this molecule are consistent with other flavonoid structures that have demonstrated safety in food applications.

However, the compound's toxicological profile, absorption, metabolism, and potential interactions have not been extensively documented in peer-reviewed literature accessible to the general public. The lack of comprehensive published safety data represents an information gap rather than an indication of hazard.

This additive has not received FDA GRAS (Generally Recognized As Safe) status. This designation indicates that the FDA has not formally affirmed the compound's safety through either the GRAS notification process or direct regulatory approval. The absence of GRAS status does not automatically indicate safety concerns; rather, it reflects that formal regulatory recognition through established FDA pathways has not been completed.

The compound's regulatory status suggests it may have limited use in FDA-regulated food products within the United States, or its use may be subject to specific regulatory frameworks depending on the food category and application. Different regulatory jurisdictions, including the European Food Safety Authority (EFSA), may have varying approval statuses for this ingredient.

Manufacturers using this ingredient must ensure compliance with applicable food safety regulations in their respective markets and may be required to document the safety of their specific applications.

Publicly available peer-reviewed literature specifically examining this compound's safety in food applications is limited. Most scientific information about flavonoids generally comes from nutritional studies evaluating their presence in foods and their bioavailability rather than toxicological assessments of individual compounds.

The scientific community continues to investigate flavonoid compounds for their properties and potential applications. Any manufacturer or importer considering use of this ingredient should consult available toxicology databases, conduct appropriate safety assessments if required by local regulations, and maintain documentation of their safety evaluations.
