Tung oil is extracted from the tree of tungueiro - Aleruites moluccana, leafy-sized, capable of reaching 10 meters tall, thin skin, pale gray, numerous branches, gathered in bouquets with canopy 50-10 meters in diameter.

 

Scientific Name: Aleurites sp.

 

Origin: The tung is native of the Far East, which grows almost spontaneously and very rapidly in China, especially in the region of the Yangtze. Currently, the main producers are China, Paraguay and Argentina.

 

Characteristics: To obtain a good yield of oil, we need a correct storage of almonds to prevent them from sour or spoil.

One of the most important properties of Tung oil and when heated to 250 ° C, takes a few moments to gum oil, forming an elastic cord, durable, insoluble in almost all common solvents, highly resistant to water action.

 

Properties: Tung oil is a major secativos oils that make it despite its high cost, an oil irreplaceable in some applications. Higher than the standard linseed oil and oil of myrtle, this fruit produces eleosteárico acid, an ingredient that accelerates the drying of paints and products.

 

Planting and Pricing: The tung is usually planted on land unsuitable, and now you topple more trees that are planted. The current exchange rate situation is taking damage, because the dollar is devalued and producers sell the product and receive in Guaraní, who also suffers sharp devaluation in Paraguay. With stocks and committed local currency devalued, the price of tung does not follow the trend of other vegetable oils. Even with the fruit harvest at full prices continue to rise.

Although the harvest has begun in July, more than half of all Paraguayan production is already committed to American and European buyers, they negotiate this oil in that country for over 30 years.
