## Detailed analysis

## What is Mountain Maple Bark?

Mountain Maple Bark, scientifically known as Acer spicatum Lam., is a flavoring ingredient extracted from the bark of the mountain maple tree, a species native to northeastern North America. The additive is assigned CAS Number 977089-64-7 and is classified as a flavoring agent or adjuvant. Like other natural flavoring extracts, it contains volatile compounds and organic constituents that contribute distinctive taste and aroma profiles to food and beverage products.

## Common Uses

Mountain Maple Bark is used primarily as a flavoring agent in the food industry. Its applications typically include:

- Beverages, particularly specialty drinks and syrups
- Confectionery and candy products
- Baked goods and desserts
- Flavor compounds in food manufacturing

The ingredient is valued for imparting authentic maple and woody flavor notes that appeal to consumers seeking natural or traditional flavor profiles. Usage levels are typically small, as is standard practice with concentrated flavoring agents.

## Safety Assessment

Based on available data, Mountain Maple Bark has demonstrated a favorable safety profile:

- **FDA Adverse Events**: Zero reported adverse events in FDA databases
- **Recalls**: No FDA-documented recalls associated with this ingredient
- **Natural Origin**: As a naturally-derived ingredient from an established plant source, it does not raise the same toxicological concerns as synthetic chemicals

The safety record reflects both the established history of maple products in food and the ingredient's limited, controlled use in food applications. However, as with any food additive, individual sensitivities or allergies remain possible, though undocumented in regulatory records.

## Regulatory Status

Mountain Maple Bark is not currently listed on the FDA's GRAS (Generally Recognized As Safe) list. This status does not indicate the ingredient is unsafe; rather, it reflects that formal GRAS determination or petition has not been completed or approved through FDA channels. Some naturally-derived flavoring agents operate under different regulatory frameworks, including those established under 21 CFR § 182 (generally recognized as safe) for natural flavoring substances.

Manufacturers using Mountain Maple Bark in food products must comply with FDA regulations for flavoring agents and ensure proper labeling and ingredient disclosure. The ingredient may be permitted in certain food categories under existing flavor regulations or petition-based approval.

International regulatory acceptance varies by jurisdiction. Some countries may have different approval statuses or usage restrictions for this ingredient.

## Key Studies

Limited published scientific literature specifically addresses Mountain Maple Bark as an isolated ingredient. Safety assessments for this additive rely primarily on:

1. **Chemical Composition Analysis**: The bark contains compounds typical of Acer species, including sugars, tannins, and volatile organic compounds associated with maple flavor
2. **Historical Use**: Maple products have a long history of culinary use in North American cuisine, supporting baseline safety assumptions
3. **Regulatory Surveillance**: Zero adverse event reports and zero recalls in FDA databases over the ingredient's period of commercial use

More comprehensive toxicological or clinical studies specific to this ingredient have not been published in peer-reviewed literature, which is not uncommon for narrowly-used natural flavoring agents. Manufacturers and regulatory bodies rely on chemical composition data, historical precedent, and ongoing post-market surveillance.
