Kola nut is the trade name for the seeds of trees of the Cola genus, especially Cola nitida and Cola acuminata. These plants are associated with tropical Africa. The seeds have a long cultural and utilitarian history, and their name entered the world language with the development of popular cola drinks.
Seeds and cultural uses
The name kola nut is used for the seeds of plants of the genus Cola, known in West African traditions. They should not be identified with any drink called cola. The drink and seed extract may have completely different compositions. In preparations, it is important to indicate the type and amount of caffeine, if it has been marked. The weight of the extract itself is not automatically the weight of caffeine and should not be presented as such in a product comparison.
Meaning and application
This does not mean that every modern drink with this name contains the identical seed extract. Kola is a natural source of caffeine and other compounds, and its taste can be bitter and astringent. Supplements use powder or extracts, the parameters of which depend on their preparation. The weight of the extract does not equal the amount of caffeine. If the recipe additionally contains guarana, tea or anhydrous caffeine, a combined declaration of caffeine content is useful. Vegetable origin does not eliminate the importance of this distinction.
In practice
The common name "nut" in this case refers to the commercial description of the seed, not to a guarantee of identity among all Cola species. The raw material can be prepared in various ways. What is important in its specification is the caffeine content, which does not automatically result from the weight of the powder or extract. If the recipe also includes other sources of this compound, their total amount is important. We should also not infer the composition of today's drink solely from the history of its name. Likewise, the traditional presence of seeds in culture is not a capsule specification. Accurate marking of the species, extract form and portion helps distinguish the history of the ingredient from the product parameters.
