What is Pine Bark, White (Pinus strobus L.)?
Pine Bark, White is a natural flavoring substance extracted from the bark of Pinus strobus L., commonly known as Eastern white pine. The additive is identified by CAS Number 977002-91-7 and functions as a flavoring agent or flavoring adjuvant in food products. Natural flavoring substances derived from plant materials like pine bark have been used traditionally in food preparation and beverages for centuries, contributing characteristic woody, resinous, and pine-forward flavor profiles.
Common Uses
Pine Bark, White is primarily used as a flavoring ingredient in food and beverage applications where pine or woody flavor characteristics are desired. These applications may include:
- Alcoholic beverages, particularly spirits and liqueurs
- Non-alcoholic beverages and flavor compositions
- Confectionery and candy products
- Savory food flavoring applications
- Natural flavor blends and proprietary flavor systems
The specific concentration and application method depend on the desired intensity of pine flavor and the compatibility with other ingredients in the final product.
Safety Assessment
Pine Bark, White has not been formally evaluated by the FDA under the Generally Recognized as Safe (GRAS) program, meaning it does not currently hold GRAS status. However, the absence of GRAS status does not indicate unsafe use; rather, it reflects the specific regulatory pathway and evaluation status of this particular ingredient.
According to FDA records, there have been zero adverse events reported and zero recalls associated with Pine Bark, White. This lack of reported safety concerns suggests a favorable safety profile in commercial food use, though the limited regulatory data reflects its relatively specialized use in flavor formulations.
Natural pine bark extracts contain compounds including phenolic substances and volatile constituents that contribute to their flavor properties. The safety of pine-derived flavoring agents depends on proper sourcing, processing, and use levels appropriate for flavoring purposes.
Regulatory Status
Pine Bark, White is not currently listed as a GRAS substance by the FDA. In the United States, flavoring substances not on the GRAS list may still be used in food products under FDA regulations when they meet certain criteria, including proper identity and specifications. Manufacturers using this ingredient should ensure compliance with FDA labeling requirements and establish appropriate use levels.
Regulatory acceptance varies internationally. The European Union's EFSA (European Food Safety Authority) maintains separate approval processes for flavoring substances used in food. Specific approval status in different regulatory jurisdictions should be verified before formulation and marketing.
Food manufacturers typically work with flavor suppliers who manage compliance with applicable regulations and maintain comprehensive safety documentation for natural flavoring ingredients.
Key Studies
Limited peer-reviewed scientific literature specifically addresses the safety and efficacy of Pine Bark, White as a food additive. Most toxicological and flavor chemistry data available relates to general pine bark extracts and their constituent compounds rather than this specific product specification.
Research on pine bark generally has focused on bioactive compounds including proanthocyanidins and phenolic substances, primarily in contexts outside food flavoring. The flavoring application of Pine Bark, White represents a specialized use case where flavor intensity typically employs very low concentration levels in finished food products.
Additional research characterizing the chemical composition and safety parameters of this specific flavoring substance would strengthen the regulatory and scientific understanding of its use profile.
