Pequi oil

Last updated

Pequi oil is a seed oil, extracted from the seeds of the Caryocar brasiliense , which is native to Brazil. The pale yellow mesocarp oil is extracted and used directly as a cooking oil. [1] In Brazil, there are projects among indigenous people groups to develop pequi oil production as a means of economic development. [2]

<i>Caryocar brasiliense</i> species of plant

Caryocar brasiliense, known as pequi or "souari nut", like its congeners, is an edible fruit popular in some areas of Brazil, especially in Brazil's central-west region.

Brazil Federal republic in South America

Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. At 8.5 million square kilometers and with over 208 million people, Brazil is the world's fifth-largest country by area and the fifth most populous. Its capital is Brasília, and its most populated city is São Paulo. The federation is composed of the union of the 26 states, the Federal District, and the 5,570 municipalities. It is the largest country to have Portuguese as an official language and the only one in the Americas; it is also one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world.

Pequi oil contains 44.2% palmitic and 51.7% oleic acid, with linolenic and stearic acids in much smaller amounts. [3]

Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and other dairy products. Palmitates are the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4).

Oleic acid monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9

Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9. It has the formula CH3(CH2)7CH=CH(CH2)7COOH. The name derives from the Latin word oleum, which means oil. It is the most common fatty acid in nature. Salts of oleic acid are called oleates.

Linoleic acid (LA) is a polyunsaturated omega-6 fatty acid and is one of two essential fatty acids for humans, who must obtain it through their diet.

Vegetable oil triglyceride extracted from a plant

Vegetable oils, or vegetable fats, are fats extracted from seeds, or less often, from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, rapeseed oil, and cocoa butter are examples of fats from seeds. Olive oil, palm oil, and rice bran oil are example of fats from other parts of fruits. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature.

Its scent is described as "slightly peppery with a hint of nutmeg" and flavor as "slightly nutty, sweet and peppery".

<i>Attalea maripa</i> palm species

Attalea maripa, commonly called maripa palm is a palm native to tropical South America and Trinidad and Tobago. It grows up 35 m (115 ft) tall and can have leaves or fronds 10–12 m (33–39 ft) long. This plant has a yellow edible fruit which is oblong ovoid and cream. An edible oil can be extracted from the pulp of the fruit and from the kernel of the seed.

Pumpkin seed Graine de courge.

A pumpkin seed, also known as a pepita, is the edible seed of a pumpkin or certain other cultivars of squash. The seeds are typically flat and asymmetrically oval, has a white outer husk, and is light green in color after the husk is removed. Some cultivars are huskless, and are grown only for their edible seed. The seeds are nutrient- and calorie-rich, with especially high content of fat, protein, dietary fiber, and numerous micronutrients. Pumpkin seed can refer either to the hulled kernel or unhulled whole seed, and most commonly refers to the roasted end product used as a snack.

Buffalo gourd oil is a seed oil, extracted from the seeds of the Cucurbita foetidissima, which is native to southwest North America. As the Latin name of the plant indicates, the vine has a foul smell. The seeds of the Buffalo gourd are rich in oil and protein, and were used by American Indians to make soap. The oil's fatty acid composition is dominated by linoleic acid (64.5%) and oleic acid (17.1%).

Belo Monte Dam hydroelectric dam complex on the Xingu River in the state of Pará, Brazil

The Belo Monte Dam is a hydroelectric dam complex currently under construction on the northern part of the Xingu River in the state of Pará, Brazil. The planned installed capacity of the dam complex would be 11,233 megawatts (MW), which would make it the second largest hydroelectric dam complex in Brazil and fourth largest in the world by installed capacity, behind the Three Gorges Dam and the Xiluodu Dam in China and the Brazilian-Paraguayan Itaipu Dam. Considering the oscillations of flow river, guaranteed minimum capacity generation from the Belo Monte Dam would measure 4,571 MW, 39% of its maximum capacity.
