Production Process.
Seed reception and warehousing
Each kind of seed, such as sunflower, soy, canola, etc., is unloaded on silos where they are kept until the production process begins. The purchase of quality seeds is crucial, since the type, cost and the seed itself can compromise the other steps of the process.

Extraction
For low fat content seeds, such as soy, extraction begins after cleaning, crushing, lamination, cooking and pressing. It's a solvent based process from which raw oil is extracted.

In the case of Sunflower and Canola (higher fat content) we have a previous step of mechanical pressing from which 70% of the raw oil results, and only the remaining is extracted by solvent.

Refining
Once it is extracted, the raw oil must be neutralized, removing the free fatty acids. It is winterized and spun to eliminate all the waxes that come from the seed shells. It is then washed and whitened to remove the oil pigments, and deodorized to remove all flavors. Refining ends with a final polish to obtain a shiny and crystal clear appearance.

Composition
In this phase, different lots of seed oils are formulated, through the combination of several seeds in exact proportions. Having products with specific characteristics allows us to better satisfy our clients and consumers.

Bottling
The different seed oil varieties are offered in PET or PEAD packages, with a capacity between 1 and 25 liters.

The boxes where the products are placed are grouped in pallets before preparing for transportation to the client.
