Murumuru fat
Murumuru fat (usually referred to as Murumuru butter ) is a vegetable fat that is extracted from the seeds of the Astrocaryum murumuru (Murumuru palm ). The seeds contain approx. 35–45% fat. It is not - as is the case with peanut butter - butter in the true sense of the word.
Origin, extraction and use
The palm is native to the Amazon rainforest in Brazil . It grows on the floodplains in the Amazon basin and bears edible fruits. When the fruits are ripe, they fall to the ground. The yellow pulp is eaten by rodents, pigs and cattle. What remains is a clean seed. The Murumuru fat is pressed from the seeds and used as a moisturizer.
Murumuru fat has strong softening and moisturizing properties and has a film-forming and naturally shiny effect. It contains vitamins. Like other fats and oils, Murumuru fat is a mainly triglyceride so a triester of glycerine. The triglycerides contain particularly high amounts of lauric and myristic acid as fatty acid residues. It is the basic ingredient for lotions , creams , soaps , hair conditioners , facial murumuru masks, shampoos and emulsions , moisturizers and depilatories.
Murumurufett is also suitable for the production of biodiesel .
