Unexpected Facts about Rapeseed Plant

Rapeseed, however still known as rape or colza, is a mustard family plant which grows for its seedlings, which also produce canola oil or rapeseed oil that also normally consists considerable quantities of erucic acid. Canola is a collective of rapeseed varieties which have been cultivated to have some very low concentrations of erucic acid and therefore are highly valued to be used as human and animal nutrition. Rapeseed seems to be the world’s third-largest cause of vegetable oil as well as second-largest protein source.

Rapeseed seems to be an annual plant that grows to a height of 30 cm upwards of and has a lengthy, generally slender taproot. It has smooth, bluish green leaves which are profoundly scalloped, and indeed the units of the upper leaves clasp the stem. Rapeseed does indeed have spikes of four-petaled yellow flowers. Thus every elongated round pod really does have a simple beak as well as a large number of seeds.

Rapeseed Plant Characterization

The Plant could perhaps reach a height of 100 cm and seems to have hairless, spongy, pinnatifid, as well as glaucous relatively low leaves that have been stalked, meanwhile the upper leaves have really no petioles. Brassica napus differs from Brassica nigra by having upper leaves that don’t really grip the stem as well as Brassica rapa whilst also having smaller petals that are somewhat than 13 mm throughout. Rapeseed flowers all seem to be bright yellow but also approximately 17 mm in diameter. They have been radial, with four petals in something like a typical cross-form alternated with four sepals. They have undefined racemose flowering that begins somewhere at lowest bud and grows upwards from the course of a few days.


The flowers have two lateral stamens with simple filaments as well as four midpoint stamens with relatively long filaments, the anthers about which divvied up away from the middle of the flower when it blooms. All through growth, the rapeseed pods have always been green but also enlarged siliquae, potentially turning brown. They develop on pedicels 1 to 3 centimeters in length and therefore can reach a size of 5 to 10 cm. Thus every pod is divided into two compartments by an interior center wall, under which a line of seeds grows. The seeds come in pair’s measure 1.5 to 3 millimeters in diameter. They have quite reticulate surface characteristics but also mature to be dark as well as tough.

What is Rapeseed plants used for?

Whenever the seeds have all been harvested, they can indeed be squeezed and then used to make cooking oil and perhaps even non-edible oils like lubricants as well as biofuels. Annual plants have always been collected for their oil. There are indeed biennial crops that were already primarily managed to grow for animal nutrition.

Canola Oil

Canola oil is being used in a number of different ways, including food preparation, as something of an active component in soap as well as margarine, and also as a lamp fuel. The esterified oil has been used as a lubricant in jet engines and therefore can be converted into biodiesel. The seeds are being used as bird food, and indeed the seed residue left over when the oil extraction has been used as fodder. The plant is suitable for use as a crop rotation and green manure.

What’s the problem with canola oil?

Just about all canola would be chemically derived with hexane, and heat has been frequently used, which could also affect the structure of the oil’s molecules, transform it rancid, severely damage the omega-3s in it, and sometimes even generate Tran’s fats. There seems to be “cold-pressed” canola oil, but it is quite complicated and expensive to discover.
