What is Pomegranate Bark, Extract?
Pomegranate bark extract (CAS Number: 977018-22-6) is a concentrated flavoring substance obtained from the bark of the pomegranate plant (Punica granatum L.). The extraction process isolates flavor compounds and aromatic constituents from the dried bark material. This extract falls into the category of natural flavoring agents and is used as a flavoring adjuvant in food manufacturing. Unlike pomegranate juice or seed extracts, bark extract specifically utilizes the outer rind material of the fruit.
Common Uses
Pomegranate bark extract is employed in the food industry as a flavoring agent to impart pomegranate taste and aroma to various products. Common applications include:
- Flavored beverages (juices, teas, energy drinks)
- Confectionery and hard candies
- Baked goods and desserts
- Flavored yogurts and dairy products
- Dietary supplements and functional foods
The extract allows manufacturers to achieve pomegranate flavoring without using fresh juice or whole fruit, offering extended shelf stability and concentrated flavor profiles.
Safety Assessment
Pomegranate bark extract presents a favorable safety profile based on available data. The FDA has recorded zero adverse events associated with this ingredient and zero food recalls involving pomegranate bark extract. Pomegranate (Punica granatum) has been used traditionally in various cultures for centuries, providing a historical safety record.
The safety of pomegranate-derived products is generally supported by scientific literature. Pomegranate bark contains compounds including tannins, ellagic acid, and punicalagins, which are well-characterized plant constituents. While these compounds have been studied for potential health effects, normal food use levels are substantially lower than those used in clinical research.
As with any concentrated plant extract, appropriate quality control and manufacturing standards should ensure microbial safety, proper extraction methodology, and absence of contaminants. Individual sensitivities to pomegranate products are rare but theoretically possible.
Regulatory Status
Pomegranate bark extract is not on the FDA's Generally Recognized as Safe (GRAS) list, meaning it has not undergone the formal GRAS notification process or been officially affirmed as GRAS. However, this does not indicate the ingredient is unsafe; rather, it reflects that a formal GRAS petition has not been submitted to or approved by the FDA.
In the European Union, pomegranate extracts fall under the flavor regulations, and various pomegranate-derived flavoring substances are permitted in food products. The regulatory landscape for this specific bark extract may vary by jurisdiction, and manufacturers should verify compliance with local regulations in their intended markets.
The ingredient may be used in food products under FDA regulations if it meets the criteria for use as a flavoring substance, though manufacturers should maintain documentation supporting the safety of their specific extract formulation and application.
Key Studies
While pomegranate bark extract specifically has limited published research, the parent plant (Punica granatum) has been extensively studied. Scientific literature on pomegranate components demonstrates:
- Characterization of pomegranate bark's chemical composition and polyphenol content
- Traditional use documentation across Mediterranean and Middle Eastern food systems
- Studies on pomegranate polyphenols and their chemical stability during food processing
- Research on pomegranate safety in food and beverage applications
The absence of adverse events reported to the FDA and the lack of recalls provide real-world safety data supporting the safe use of this flavoring agent in food products. Additional toxicological studies on the specific extract formulation may provide further characterization, though the existing data supports continued use as a flavoring agent at typical food application levels.
