It is considered a healthier alternative to many other cooking oils and finds extensive usage in food preparation, salad dressings, or as a base for margarine.
Apart from its culinary uses, rapeseed oil also serves as a raw material for the production of biodiesel. The oil undergoes a process called transesterification, where it is converted into an alternative fuel source that can be used in diesel engines. This makes B. napus not only an economically significant crop but also an environmentally sustainable one.
Overall, Brassica napus is a flowering plant cultivated primarily for its oil-rich seeds, which have multiple applications in both the culinary and industrial sectors. Its versatility, adaptability, and nutritional attributes have made it a valuable agricultural commodity worldwide.
