Balsam Peru is among the 80 natural flavorings that the Society of Flavor Chemists requires flavorists to master. For each substance, a flavorist must be able to identify the part of the plant used, its derivatives, its organoleptic properties, and the primary chemical components responsible for its characteristic aroma and flavor.

Myroxylon balsamum var. pereirae (Balsam Peru / Peru Balsam) is a classic flavor and fragrance raw material obtained from a Central American tree. It is widely used in flavor compounding (especially sweet, vanilla-type bases), perfumery, and pharmaceutical preparations.

1. Plant Parts Used

The material is obtained from the trunk bark.

Process:

1. The bark of the tree is beaten, scorched, or incised.
2. The injured bark exudes a dark aromatic resin.
3. Cloths absorb the resin.
4. The cloths are boiled in water, and the balsam sinks and is collected.

Plant part used:

• Bark exudate (oleoresin/balsam) from the trunk.

2. Derivatives of Balsam Peru

Common commercial derivatives include:

3. Organoleptic Characteristics

Aroma / flavor profile

Primary notes:

• Sweet
• Balsamic
• Vanilla-like
• Warm resinous
• Cinnamon-like
• Slightly smoky
• Caramelic
• Soft chocolate nuance
• Slight clove/spice

Flavorists often describe it as:

“Vanilla + cinnamon + benzoin + caramel + mild clove.”

Taste:

• Sweet
• Slightly bitter
• Warm aromatic

Appearance:

• Very viscous dark brown liquid
• Sticky resin

4. Major Aroma-Active Chemical Components

Peru balsam is chemically rich, dominated by benzyl esters and cinnamate derivatives.

Key Character-impact compounds

5. Compounds Most Responsible for the Characteristic Aroma

The signature Peru balsam odor is mainly produced by:

1. Benzyl benzoate
2. Benzyl cinnamate
3. Cinnamic acid derivatives
4. Vanillin (minor but important)

These create the sweet balsamic vanilla–cinnamon profile.

6. Simplified Flavorist “Aroma Core”

A flavor chemist would summarize the character as:

Benzyl benzoate      → balsamic sweetness
Benzyl cinnamate     → warm cinnamon balsamic
Cinnamic acid        → spicy warmth
Vanillin             → sweet vanilla softness
Coumarin (trace)     → hay/tonka sweetness

7. Typical Flavor Applications

Peru balsam is used at very low levels as a modifier.

Applications include:

• Cola flavors
• Root beer
• Vanilla bases
• Chocolate flavors
• Tobacco flavors
• Spice blends
• Liqueur flavors
• Baked goods
• Caramel flavors

Typical usage: 1–50 ppm in finished food. t
