Oilseed Products

Canola was developed in Canada in the 1970s breeding out unhealthy components of rapeseed to produce a product suitable for consumption. Its oil has a different composition than rapeseed and meets stringent standards to fit the industry definition of canola. Only then can it be sold under that trademarked name.

“Canola oil has one of the lowest levels of saturated fat among cooking oils and no trans fats,” said Dr. Sharon Robinson, Extension nutrition specialist. “It is rich in vitamin E and essential fatty acids – nutrients needed to help maintain health. In fact, canola has more vitamin E than peanut, corn or olive oil.”

Along with oil, canola is used in making salad oils, sandwich spreads, coffee creamers and other edible products. Canola meal is processed into pellets and mash to make feed for pigs, cattle and poultry. It is also used in pesticides, lubricants, printing inks, cosmetics and other non-edible products.

Biofuel is considered an important means of reducing greenhouse gas emissions and increasing energy security by providing a viable alternative to fossil fuels.

Biofuels are commonly used throughout the world. The most common use for biofuels is automotive transport (E10 fuel). Essentially a biofuel can be produced from any short term carbon cycle organic compound; due to this there is a high variety of resources and therefore many types of biofuels.

In the United States, soy beans provide the primary feedstock for biodiesel production. Palm oil from southeast Asia has also emerged as a low cost feedstock for biodiesel production. Both of these feedstocks will compete for market share with locally grown oilseed crops.

Canola crop

In the Northwest, the focus is on brassica crops, which includes canola, rape and mustard. These oilseeds have been used in limited applications as a rotation crop with wheat and barley. The benefit of rotating oilseed crops with cereal grains is that they allow a wider choice of herbicide use, improving weed control. The addition of oilseed crops also helps loosen hardpan and can be direct-seeded or no-till farmed, reducing soil erosion impacts and breaking disease cycles. The brassica oilseeds contain a high oil content which makes them a good candidate for producing feedstock oils for biodiesel. For example, spring canola contains upwards of 42 percent oil as compared to an oil content of about 20 percent for soybeans. A comparative table showing oil yields from various oil producing crops is shown below.

Oilseed crushers

Crushers are used to extract oil from oilseed. This involves a series of steps which can include mild heat treatment to precondition the seed prior to processing. Next the seed is crushed and flaked and then heated slightly to enhance oil extraction. The flakes are then pre-pressed in a screw press or expeller to reduce the oil content in the seed. For canola this step reduces the oil content from about 42% to 16-20%. The press cake is then subjected to one of two types of oil extraction to remove much of the remaining oil. Oil may be extracted using either hexane (“solvent”) extraction or by “cold-pressing” (also referred to as “expeller pressing”). The oil which is produced during the extraction process is referred to as “crude oil”.

Co-Products

Oilseeds such as canola, rape and mustard are generally not grown as primary crops, but can be used as a rotational crop in the cultivation of wheat or other grains. Farmers evaluate oilseeds profitability against other rotational crops. To plant oilseeds, a farmer must be convinced that the economic returns for these crops are at least as good as other alternatives. The value of oilseeds as a biodiesel feedstock depends upon a number of factors:

  • value of fossil diesel;
  • value of tax incentives;
  • value of seed meal;
  • value of glycerol (a co-product of biodiesel production);
  • cost of crushing oilseed; and
  • cost of processing seed oil into biodiesel.

While all of these factors are important, the development of higher value seed meal markets may be the most significant. As of now, canola meal is sold as an animal feed supplement. This market does not provide the economic returns needed by most growers to justify planting oilseeds. Instead higher value markets are needed-from increasing the value of the meal as an animal feed, to using it as a high value fertilizer, a biopesticide, as food for human consumption, or as a feedstock for other bioproducts. There is also an increasing demand from organic dairies for high value organic meal.

How We Operate

The Oklahoma Oilseed Commission identifies and coordinates state-wide programs for oilseed, oilseed resources, oilseed market development, oilseed promotion, and education relating to oilseed. Please take a look at our resources to see how our organization operates. The commission has been formed to help Oklahoma’s farmers. Read the following documents for more information on how the commission operates.
