Sunflower vegetable oil is obtained by cold pressing the seeds of Helianthus annuus L., belonging to the Asteraceae family. This annual plant can grow up to three meters in height. Its stems are rough, erect, with alternate, petiolate leaves that have serrated edges.

On the underside, leaves are rough, sometimes glandular, while the upper side remains smooth, providing a clear texture contrast. The involucre is hemispherical, measuring 15-40 mm, with lanceolate, veined bracts, which are typically rough in texture.

Ligules can be yellow, orange, or red, ranging from 2.5 cm to 5 cm. Florets, numbering 150 to 1000, share the same color and feature reddish-brown stamens. Fruits are oval achenes, measuring 3-15 mm, dark or speckled. The pappus consists of two lanceolate scales, 2-3.5 mm, sometimes with smaller scales.
