So, let’s explore what makes canola seeds so special and how you can incorporate them into your gardening and cooking adventures.

Definition of Canola Seed

Canola seeds are the tiny, oval-shaped seeds from the canola plant (Brassica napus), which belongs to the same family as mustard, broccoli, and cabbage. Canola seeds are often referred to as “oil seeds” because they are primarily cultivated for their oil content.

The term “canola” is derived from “Canadian oil, low acid,” which indicates the key qualities of these seeds. Canola seeds were developed in the 1970s through selective breeding to reduce the levels of erucic acid and glucosinolates, making them safe for consumption and suitable for use in food applications.

In order for a variety of rapeseed to be classified as canola, it must meet specific criteria set by regulatory bodies. These criteria include having an oil content of at least 40%, low levels of erucic acid (less than 2%) and glucosinolates (less than 30 micromoles per gram), and meeting certain purity standards.

Canola seeds are commonly processed to extract their oil, which is widely used in culinary applications, such as cooking, baking, and salad dressings. The remaining byproduct after oil extraction, known as canola meal, is often used as a protein-rich animal feed.

History and Origin

The history of canola seeds can be traced back to ancient times when they were originally cultivated for their use as a lamp fuel and in traditional medicines. However, the development of the canola plant as we know it today is more recent.

The cultivation and selective breeding of canola seeds began in the 1970s, primarily in Canada, where researchers aimed to improve the nutritional profile and reduce the levels of harmful compounds in rapeseed plants. Rapeseed, from which canola seeds are derived, has been grown for centuries, but it contained high levels of erucic acid, which can be harmful to human health and undesirable for consumption.

In the 1960s, Canadian scientists discovered a natural variant of rapeseed with lower levels of erucic acid. Through continued research and selective breeding, they were able to develop varieties of rapeseed that met the stringent criteria for safety and quality set by regulatory bodies. These new varieties of rapeseed, low in erucic acid and glucosinolates, were then given the name “canola” to distinguish them from traditional high-erucic acid rapeseed.

The introduction of canola seeds revolutionized the oil industry, offering a safer and more nutritious alternative to traditional rapeseed oil. Canola seeds quickly gained popularity and their cultivation rapidly expanded across Canada and other countries around the world. Today, Canada is one of the leading producers of canola seeds, followed by China, India, and the United States.

With a rich history steeped in scientific innovation and agricultural advancements, canola seeds have become an integral part of the global farming landscape. Their cultivation and usage continue to evolve, driven by the increasing demand for healthier and more sustainable food options.
