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.
