Canola crops

Japan uses large amounts of canola oil. It has been an importer of Canadian canola seeds since the introduction of canola in the early 1970s, and it has for many years taken about one-half of the Canadian canola crop. The oil is predominantly used in liquid, nonhydrogenated form as cooking oil, salad oU, and salad dressings oil, pure, as well as in blends with other oils. Further, in a new development, it is used as base oil to produce dietetic cooking and salad oils made up of... 

As both Sunola crops are special, care must be taken against contamination with traditional sunflower or canola. However, this is rarely the case, as Sunola is grown in northern areas of the United States, where regular sunflower is not grown and in areas of southern Canada that are too hot and dry for the development of canola crops. 

In addition to the conventional listing of major constituents, a commercial blend may be formulated to contain one or more of the secondary constituents, calcium, magnesium, or sulfur, which are used to correct local soil deficiencies. These are normally specified in a separate listing. The importance of these, too, cannot be overlooked as, for example, fertilization of a sulfur deficient soil with soluble sulfate has given over 1100% rapeseed (canola) crop improvement [69].

Oily crops such as soybeans and canola (oilseed rape) cannot be extracted with aqueous buffers, because the extraction solvent cannot permeate the hydrophobic plant tissue matrix. In these cases, homogenization in acetonitrile-hexane is recommended. This solvent mixture is able to extract sulfonylureas from these samples with a minimum of co-extracted oil. After extraction, the sulfonylureas partition into the acetonitrile phase while most of the oil stays in the hexane phase. Further cleanup is accomplished using a silica SPE cartridge and normal-phase conditions. 

Tolerance of GM seeds in non-GM varieties ranges from 0 to 5% in different countries (ISF, 2004). It is widely agreed that it is impossible to maintain or guarantee that seed from a crop such as maize, soybeans, canola or cotton is absolutely free of GM seeds. It should be reiterated that IFOAM opposes mandatory testing for GM contamination and proposes that organic farmers do not have to prove that their crops are GM-free (IFOAM, 2002). The International Seed Federation (ISF) proposed that its 70 member countries...

Brassica napus is a widely grown crop used primarily for the production of oil, which is classed as either rapeseed oil or canola oil depending on its quality and content. 

Glufosinate has a broad weed spectrum (little to no selectivity), and is therefore sometimes marketed along with genetically engineered glufosinate-resistant crops (cotton, canola, maize, and rice). While this raises some concern in some parts of the world, transgenic technology has been widely accepted in the western hemisphere. Nevertheless, neither...
