High erucic acid rapeseed

However, the introduction of canola left unmet needs for erucic acid in industrial markets. High-erucic acid rapeseed then was imported from Northern Europe for extraction, followed by efforts to increase erucic acid contents in domestic industrial rapeseed as well as development of crambe (Crambe abyssinica) specifically for its erucic acid content. At the current state of development, equipment corrosion and poisoning of hydro-... 

By elimination of erucic acid from traditional high erucic acid rapeseed, the C22 fatty acid family also was eliminated. The replacement canola (low-erucic-acid rapeseed) had one less variety of fatty acids, and became a /3 crystallizer. 

Fully Hydrogenated Rapeseed Oil occurs as a white, waxy, odorless solid that is a mixture of triglycerides. The saturated fatty acids are found in the same proportions that result from the full hydrogenation of fatty acids occurring in natural high erucic acid rapeseed oil. The rapeseed oil is obtained from Brassica juncea,... 

Brassica napus, and Brassica rapa of the family Cruciferae. It is made by hydrogenating high erucic acid rapeseed oil in the presence of a nickel catalyst at temperatures not exceeding 245°.

In China, canola-type rapeseed oil products still contribute a very small proportion of total rapeseed oil products. Oil from both high erucic acid rapeseed and canola rapeseed represent the largest use of edible oil at present. The oil from these two sources is almost entirely used as cooking oil. There are very little amounts of this oil used for margarine or shortening formulations at present. Efforts are being made to widen the spectrum of edible oil products and convert from HEAR cultivation to canola cultivation.

Crambe (Crambe abyssinica) and high-erucic acid rapeseed (Brassica napus) are oilseeds that contain large quantities of erucic acid 22 1 (A 13) as the main fatty acid component of the triglyceride. Crambe and high-erucic acid rapeseed (HEAR) contain 59.5 and 42% erucic acid, respectively (2). HEAR has more oil in the seed (42% compared with 35% for crambe). Both oilseeds are in commercial production with acreage in the tens of thousands and are grown mainly in the northern plains of the U.S. and Canada as well as eastern Europe (3).

In the Orient, both rapeseed and mustard oils are used extensively for food and large quantities of mustard are produced for oil in India, Pakistan and Bangladesh. In Canada and Europe there is no production of mustard oil for edible oil purposes. All edible Canadian rapeseed oil is now from canola varieties, i.e., derived from seed low in erucic acid and low in glucosino-lates. High erucic acid rapeseed oil is used exclusively for industrial purposes, such as lubricants, slip agents for molds, and polymers. In Canada these high erucic acid oils are produced and marketed separately from canola oil. Rapeseed oils in the Western World are either very low in erucic acid for edible use or very high (over 40%) in erucic acid for industrial use. 

The magnitude of the variation in the composition of rapeseed oil and meal now commercially available has created a need for new terms to describe the products derived from rapeseed. The fatty acid composition of most edible vegetable oils such as soybean, sunflower, or cottonseed oils, varies within narrow limits. Thus, the species or commodity name (e.g., soybean oil) provides a reasonable description of the fatty add composition of soybean oil. In contrast, the erucic acid content of commercially available rapeseed oil may vary from near zero to 55%, and the oleic acid from 10 to more than 60%. A number of terms have been proposed or utilized to describe the new rapeseed oil whose fatty acid composition has been altered by the elimination of erucic acid these include low erucic acid rape-seed oil (LEAR), canbra, and canola. Similar terms such as high erucic acid rapeseed oil (HEAR) and common or traditional rapeseed oil have been used to describe rapeseed oil whose fatty acid composition includes substantial amounts of erucic acid.
