The nutty element in combination with the sulfur notes would make it a great addition to chocolate flavors, but also nut profiles. Moreover, its meaty, brothy character would provide complexity to various savory tonalities, such as chicken and beef.

Massoia Lactone, EU Natural

• Botanical Name: Cinnamomum cassia Blume.
• Characteristics: The cinnamon oil from China is known as “cassia oil,” which is a slightly different variety from the Indian or Sri Lankan types, which are traded as “cinnamon oils.” The leaves and branches are distilled across all origins, but whilst the bark is used in Sri Lanka, it is rarely used in China.

Lime Oil Distilled West Indian Type

FEMA# 2632, CAS# 90063-52-8.

• Botanical Name: Citrus aurantifolia (Christman) Swingle.
• Characteristics: The screw-pressing of the fruit produces a juice-essential oil emulsion.
