Introduction
Oil used in cooking foods is commonly derived from vegetable. Cooking oil is high in fat calories. Unsaturated and saturated oils have approximately the same number of fat grams and calories. Olives, safflower, corn, cottonseed, canola, sunflower seed, soy palm and coconut oil all contain about 13.5 grams fat and 120 calories per tablespoon. Cooking oil is commonly used for frying and it’s usually thrown away. The recycling of cooking oil also provides a form of revenue for restaurants, which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed of in drains, which can clog sewage lines due to the build-up of fats.
