Interesterification is typically carried out using a catalyst, such as sodium methoxide, and is performed under mild conditions. The resulting product is a triglyceride with a modified fatty acid composition that is more suitable for use in margarine production. Both hydrogenation and interesterification are important steps in the margarine manufacturing process, as they allow for the production of a high-quality margarine with a desirable texture and flavor.

Churning and Crystallization

Churning and crystallization are critical steps in the margarine manufacturing process, transforming the blended mixture of oil and water into a smooth, creamy, and solid spread. Churning involves agitating the mixture to break down the fat molecules and distribute them evenly throughout the liquid, creating a uniform emulsion. This process can be achieved through various methods, including mechanical churning, ultrasonic churning, or even high-speed mixing. The churning action introduces air into the mixture, which helps to incorporate the fat molecules and create a lighter, more aerated texture. As the mixture churns, the fat molecules begin to coalesce and form a network of crystals, marking the beginning of the crystallization process. Crystallization is a complex process that involves the formation of a crystal lattice structure within the fat molecules, which gives margarine its solid texture and stability. The rate and extent of crystallization can be influenced by factors such as temperature, pressure, and the presence of additives, such as emulsifiers and stabilizers. By carefully controlling the churning and crystallization processes, manufacturers can produce margarine with a range of textures and properties, from soft and spreadable to firm and butter-like.
