caustic soda can be used in the beverage industry for various applications, including cleaning and sanitizing equipment and facilities.In the production of beverages, caustic soda is commonly used as a cleaning agent to remove stubborn stains, dirt, and bacteria from processing equipment, pipelines, and storage tanks. It can be used in both hot and cold cleaning processes to dissolve organic materials and mineral deposits that may have accumulated on the equipment’s surfaces.
Additionally, caustic soda is used to adjust the pH levels of beverages such as fruit juices and soft drinks. By adding caustic soda, manufacturers can neutralize acids in the beverages and make them less acidic, resulting in a milder taste.
During the refining process, crude vegetable oil may contain impurities such as free fatty acids, phospholipids, and pigments. Caustic soda is added to the oil to remove these impurities through a process called neutralization. The caustic soda reacts with the free fatty acids to form soap, which can be easily separated from the oil. This process helps to improve the oil’s color, taste, and stability.
Caustic soda can also be used in the deodorization process of edible oils. During deodorization, caustic soda is added to the oil to remove any volatile compounds that may affect the oil’s taste and aroma. The caustic soda reacts with these compounds, forming non-volatile compounds that can be easily removed from the oil.
