What is Orange Flowers, Bitter?
Orange Flowers, Bitter, scientifically known as Citrus aurantium L., is a natural flavoring ingredient extracted from the flowers of the bitter or Seville orange tree. The ingredient is designated by CAS Number 977051-52-7 and contains volatile compounds and aromatic constituents that contribute distinctive citrus and floral notes to food products. Bitter orange flowers have been used in culinary and perfumery applications for centuries, particularly in Mediterranean cuisine and traditional preparations.
Common Uses
Bitter orange flowers are primarily used as a flavoring agent in the food and beverage industry. Applications include:
- Beverages (liqueurs, cocktails, soft drinks)
- Baked goods and confectionery
- Desserts and ice creams
- Flavor compositions for various food products
- Traditional culinary preparations in Mediterranean cuisine
The ingredient functions as both a primary flavoring agent and as an adjuvant to enhance or modify other flavors in food formulations. Typical usage levels are relatively low, as the concentrated floral and citrus notes are potent.
Safety Assessment
Orange Flowers, Bitter has not been granted Generally Recognized As Safe (GRAS) status by the FDA. However, according to FDA records, there have been zero reported adverse events associated with this ingredient and zero product recalls attributed to its presence in food products. The absence of adverse event reports and recalls suggests it has not raised significant safety concerns in the marketplace.
The safety profile of natural citrus flower extracts generally appears favorable based on historical use in food applications. As a plant-derived ingredient, it contains naturally occurring volatile compounds typical of citrus flowers, which have been safely consumed in traditional food preparations and beverages for extended periods.
Individuals with citrus allergies or sensitivities should exercise caution, as the ingredient is derived from citrus fruit trees and may trigger allergic responses in susceptible persons. Pregnant women should consult healthcare providers regarding use, as some traditional sources suggest caution during pregnancy, though scientific data on this topic is limited.
Regulatory Status
Orange Flowers, Bitter is not listed as a FDA-approved food additive with formal GRAS determination. This does not necessarily indicate safety concerns but rather reflects the regulatory classification pathway for this particular ingredient. The ingredient may be used in food products under different regulatory frameworks or grandfathered status in certain jurisdictions.
Regulatory status varies internationally. In the European Union, natural flavoring ingredients derived from plants are subject to evaluation by the European Food Safety Authority (EFSA). Manufacturers seeking to use this ingredient should verify current regulatory approval in their specific market and jurisdictions.
The lack of formal FDA GRAS status does not preclude use in food products but may require documentation of safety or appropriate regulatory authorization depending on product category and intended use.
Key Studies
Limited peer-reviewed scientific literature specifically addresses Orange Flowers, Bitter as a food additive. Most available data on bitter orange relates to the fruit itself rather than isolated flower components. General research on Citrus aurantium indicates the plant contains compounds such as synephrine and other alkaloids, though concentrations in floral extracts typically differ from whole fruit extracts.
The absence of FDA adverse event reports and recalls over the history of this ingredient's use suggests adequate safety margins in typical food applications. Further controlled studies examining long-term consumption patterns and specific toxicity parameters could provide additional safety data, though the current absence of reported problems indicates low risk under normal use conditions.
