Definition
Noun: * Almond tree with bitter nuts: A specific type of almond tree (Prunus dulcis var. amara) characterized by white blossoms. Its nuts are poisonous when raw due to the presence of amygdalin, a compound that can release cyanide. The oil extracted from these bitter almonds is used in small, controlled quantities for flavoring foods and in some medicinal applications.
Usage Notes
- This term is a scientific botanical name. In everyday language, the tree and its nuts are more commonly referred to as "bitter almond."
- The key distinction from the common edible almond ( var. , or sweet almond) is the toxicity of its raw nuts and the intense flavor of its derived products.
- The oil must be properly processed to remove the toxic components before it is safe for use.
Examples
- The Prunus dulcis amara is cultivated not for its nuts but for the oil derived from them.
- The flavoring in this marzipan comes from the oil of Prunus dulcis amara.
- Unlike sweet almonds, the nuts of Prunus dulcis amara contain amygdalin.
Advanced Usage
- In botanical and horticultural contexts, the full Latin binomial is used for precise classification.
