Abstract

Vegetable oil fractionation is a technology used to modify the physicochemical properties of oils and to obtain optimized fractions for different industrial applications. This process allows the separation of fractions with different melting points, such as stearin and olein, depending on their triglyceride composition. Fractionation methods are divided into three main categories: dry (direct), solvent, and detergent (surfactant-assisted) fractionation. The dry fractionation method is widely preferred because it is environmentally friendly and economical.
In the fractionation process, parameters such as cooling rate, crystallization temperature, mixing speed, and time play a critical role. These parameters are controlled by statistical experiment design, response surface methodology, and artificial intelligence applications. The resulting products have various uses in the food, cosmetics, and pharmaceutical industries. For example, stearin from palm oil is used to produce and shorten margarine, while olein is used as a frying oil.
Technological advances enable more specific and functional oil fractions to be obtained. Research on green technologies such as supercritical CO2 extraction and bio-based solvents continues within the scope of environmental sustainability. In the future, genetic engineering and enzyme technologies are expected to contribute to developing products that do not contain trans fats and have high oxidative stability.
