Brazil nut: good and harm

Brazil nut: good and harm

Brazil nuts are the fruits of high bertolet (Bertholletia excelsa), a tree that is the only member of the Lecithis family and grows in the primary forests of the Amazonia (in Bolivia, Brazil, Peru). Nuts intended for delivery to the international market are harvested only from wild-growing trees (plantations are considered low-productivity and disadvantageous due to the absence in places inhabited by humans of a sufficient number of large bees, which are the natural pollinators of this plant). This is how the program is implemented, which allows to receive income from wild tropical forests without destroying them.

Bertoletiya is a tree up to 45 meters high. The straight stem of the plant, covered with smooth gray bark, can reach 200 centimeters in diameter. The large spherical crown of a bertoletia is formed by long branches located in the upper part of the trunk. Green elongated leaves of the plant, having a smooth or jagged edge, can reach 35 cm in length and 16 cm in width. Small pale green flowers of the Brazil nut form panicles up to 100 mm long.

Bertoletiya fruits are large boxes with a hard tree-like coat having a diameter of up to 16 cm and a weight of up to 2.3 kg. In each such box you can find from 8 to 24 grains of a triangular shape, reaching 50 mm in length. Fully ripening takes at least 14 months.

Fresh brazil nuts have a pleasant aroma and break open with a slight crunch. A wrinkled surface covered with bloom and an unpleasant rancid smell are signs of spoilage. Store Brazil nuts in a tight-fitting container in a cool place, protected from light and moisture (for example, in the refrigerator). In such conditions, the fruits of helicopters retain their properties for up to 3 months. Brazil nuts are eaten raw, roasted, sprinkled with sugar or salt. In addition, they are used for the manufacture of oils used in food, medical and industrial purposes (for the manufacture of perfumes, paints, for lubrication of moving parts of mechanisms, etc.).
