Currently, fat blends are used in some sectors within the food, pharmaceutical and cosmetic industry. The individual preparation of this mixture is based on the requirements of customers to meet the specific needs of each client. In most fatty mixtures refined vegetable oils are used. The number of different vegetable oils can vary from 2 to 8. Most mixtures include soybean oil, corn, sunflower, peanut, olive, wheat germ, rapeseed, coconut and palm. However, some fat blends also include special oils, such as TCM oil, medicinal cod liver oil or castor oil.
