Tucum, you guessed it from the name, is another butter of South America. It is obtained from the fruit of the palm tree which is very aggressive and likes to grow in areas ravaged by fire as one of the first species to conquer the terrain. Tucum fruit is edible and contains, like avocado, a lot of lipids and carotenoids. It is an integral part of many desserts.
As if its exoticism is not enough, tucum gives not just one, but even two butters / oils:
- butter from the seeds
- oil from pulp
As there are no norms, we will make a comparison of these two products from .

As can be seen from the table, the seed oil contains high levels of lauric and myristic acid, so it is another butter, along with babassu, coconut and murumuru, that contains them in that amount. Consequences? As always- fast-absorbing oils and butters for massage, hair treatments, production of nicely foaming soaps.
The content of sterols, among which β-sitosterol dominates, is 1.07-1.42g/kg. It contains only 10 -20mg/kg of tocopherol, among which the main proportion is α-tocopherol. There are less than 10mg/kg carotenoids, so this butter is usually very pale in colour.
Pulp oil contains far more unsaturated fatty acids, mostly oleic and linoleic. It contains a lot more carotenoids, from 1.64-2.42g/kg which is a relatively high level and can be compared to buriti oil. In it, as in buriti, β-carotene predominates completely, and to a lesser extent α-carotene. It contains 40-150 mg of vitamin E (mainly α-tocopherol). Carotenoids are a well-known group of compounds that protect the skin from damage caused by a stressful environment, and are used in anti-age cosmetics, which has already been written about in the descriptions of rosehip seed oil, buriti oil and sea-buckthorn pulp oil. Due to carotenoids, it is also used to make sunscreens, as it prevents damage to the skin caused by UV rays.
