Rhatany, Extract (krameria Spp.)

Rhatany extract (CAS Number: 84775-95-1) is a flavoring ingredient derived from plants of the genus Krameria, commonly known as rhatany or ratany plants. These woody shrubs are native to South America, particularly Peru and Bolivia. The extract is obtained from the roots and stems of the plant and has been traditionally used in folk medicine and as a flavoring agent in various food and beverage applications. The extract contains tannins and other polyphenolic compounds that contribute its characteristic astringent and bitter taste profile.

Rhatany extract functions as a flavoring agent or flavoring adjuvant in the food industry. It is primarily used in small quantities to add depth and complexity to beverage formulations, particularly in herbal teas, bitters, and other specialty drinks. The astringent properties make it useful for creating mouth-feel sensations valued in certain culinary applications. Due to its traditional use and existing applications, it may appear in some dietary supplements and herbal products, though regulatory requirements vary by region and product type.

According to FDA records, there are zero reported adverse events associated with rhatany extract and zero product recalls involving this ingredient. This indicates no documented safety incidents in the U.S. food supply where this additive has been used. However, the absence of adverse events does not inherently indicate safety approval, as comprehensive toxicological studies may be limited for this particular ingredient.

The tannin content in rhatany extract is noteworthy from a safety perspective. Tannins are natural compounds found in many plants and are generally recognized as safe in moderate amounts. However, high tannin intake can interfere with nutrient absorption and may have other physiological effects. The typical use levels of rhatany extract in food are generally low, which would limit tannin exposure from this source.

Rhatany extract is not listed as GRAS (Generally Recognized as Safe) by the FDA, meaning it has not undergone the formal GRAS determination process or does not have sufficient history of common use in food to qualify for this designation. This status does not necessarily indicate the ingredient is unsafe; rather, it reflects that the FDA has not completed or received a formal GRAS petition for this substance.

The ingredient may be permitted in certain food categories under different regulatory frameworks in other regions. In the European Union, flavoring substances are subject to EU Regulation 1334/2008, which maintains lists of approved flavorings. The regulatory status of rhatany extract varies internationally and manufacturers must ensure compliance with local regulations before use.

Any company wishing to use rhatany extract as a food additive in the United States would need to either obtain GRAS status through a formal petition process or secure FDA approval as a food additive, providing comprehensive safety data to support its use.

Scientific literature on rhatany extract is limited compared to more commonly studied food additives. Most available research focuses on the traditional medicinal uses of krameria species and the characterization of tannin compounds present in the plant. Phytochemical analyses have identified the primary active components, including various tannins and flavonoids. However, formal toxicological studies, long-term safety assessments, and human consumption studies specific to food-grade rhatany extract are sparse in published literature.

The traditional use of rhatany in South American folk medicine and historical use in beverages provides some basis for safety assessment, though traditional use does not constitute modern scientific evidence of safety. Additional research would be beneficial to establish comprehensive safety profiles for food applications.
