Study Notes
Edible Oils and Fats
- Edible oils and fats are organic substances extracted from plants and animals.
- They are commonly used in cooking, food production, and other applications.
Definitions
- Edible Oils: Liquid at room temperature, extracted from plants, primarily used in cooking, baking, and salad dressings. Examples include olive oil, sunflower oil, and canola oil.
- Edible Fats: Solid or semi-solid at room temperature, often derived from animals (butter, lard). Some plant-based fats (coconut oil, palm oil) also fall under this category.
World Edible Oil Production
- Global production of edible oils has increased due to growing demand.
- The leading contributors are palm oil, soybean oil, and canola oil.
- Key producers include countries in Asia (Indonesia, Malaysia), the United States, Brazil, and Argentina (for soybean oil).
- Production numbers are affected by agricultural practices, climate change, and global market demands.
Common Edible Oil Sources
- Palm Oil: Extracted from oil palm fruit; used in food, detergents, cosmetics, and biofuels.
- Soybean Oil: Derived from soybeans; widely used in cooking and industrial applications.
- Canola Oil: From canola plant seeds; known for low saturated fat content.
- Olive Oil: Extracted from olives; valued for taste and health benefits, especially in Mediterranean cuisine.
- Sunflower Oil: From sunflower seeds; appreciated for its light taste and high vitamin E content.
- Coconut Oil: Derived from coconut meat; used in cooking, cosmetics, and medicinal products.
- Corn Oil: Derived from corn kernels; commonly used in frying due to high smoke point.
Plants Used to Produce Edible Products
- Soybean, cottonseed, sunflower seed, safflower seed, corn germ, peanut, olive, rice bran, rapeseed, canola, coconut, palm fruit, and carob.
Animal Sources and Animal Fats
- Cattle, sheep, pigs, fish
- Butter, lard, tallow, whale oil, and fish oil.
