Oils and Fats

Cooking oils and fats come in a huge variety of flavors, types and blends. Consumers and food service establishments demand options such as cold-pressed, refined, virgin, extra virgin and other varieties to meet different nutritional requirements, diets and cuisines. Food producers need to ensure that their oils and fats are thoroughly tested and analyzed in order to fully disclose information about their contents, quality and purity to their customers. Conducting tests, and other analysis, regarding fats and oils ensures the safety and quality of all products. Testing also helps prevent potential spoilage due to rancidity as it can help determine the shelf life of the products


Rancidity and physical characteristics are the two main types of testing done to fats and oils.  Rancidity tests examine the quality and shelf life of a product.  It is useful for the safety of consumers and manufacturers. 

Fats, Oils and Oilseeds Testing examine the level of oxidation in a sample and it’s physical characteristics.  Different rancidity tests can provide the manufacturer with information about the oil’s stability, quality and longevity.  Physical tests can provide information about characteristics such as smoke point or color
