It is also used in beauty products due to its moisturizing and nourishing properties.


Flaxseed (Linseed):

Flaxseed oil is known for its rich omega-3 fatty acid content. Flaxseed oil is extracted from flaxseeds, which are primarily grown in countries like Canada, China, and India. Flaxseed oil is obtained by cold-pressing the seeds to preserve the delicate omega-3 fatty acids. Flaxseed oil has a nutty flavor and is not suitable for cooking at high temperatures due to its low smoke point. Instead, it is used as a finishing oil for salads and drizzled over cooked dishes. Flaxseed oil is known for its potential health benefits, such as reducing inflammation and supporting heart health.



Hempseed oil is emerging as a nutritional powerhouse. Hempseeds come from the hemp plant, a variety of Cannabis sativa. Hempseed oil is extracted by cold-pressing the seeds to obtain a greenish oil with a nutty flavor. Hempseed oil is rich in omega-3 and omega-6 fatty acids, making it beneficial for heart health. It also contains gamma-linolenic acid (GLA), a rare and beneficial type of omega-6 fatty acid. Hempseed oil has a low smoke point, so it is best used as a finishing oil for salads and cooked dishes. Hempseed oil is also used in cosmetic products for its moisturizing and anti-inflammatory properties.


Lesser-Known Oilseeds:



Safflower seed oil has medicinal properties and culinary applications. Safflower seeds are primarily grown in countries like India, the United States, and Mexico. The oil extraction process involves cold-pressing or solvent extraction to obtain safflower oil. Safflower oil has a mild flavor and is often used in cooking as a substitute for other cooking oils. It has a high smoke point, making it suitable for high-heat cooking methods like frying and baking. Safflower oil is also used in traditional medicine for its potential health benefits, such as reducing inflammation and promoting heart health.
