When vegetable oils come into contact with oxygen, they become especially prone to spoiling. Atmospheric oxygen causes a chemical reaction when fatty acid attacks triglyceride molecules. Oxygen and humidity is removed from the environment thanks to nitrogen gas practices and oil’s structure is preserved.
Blanket
Nitrogen gas creates an inert atmosphere inside the storage tanks and ensures that the oxygen and humidity is removed. Products remain stable and they are stored in a humid free environment without changing the amount of acidity and the taste does not change. The pressure of the nitrogen gas compressed into blanket tanks is increased to help with the transfer of the oil.
Line Cleaning
Due to the hygiene requirement in food processes, this application type that is constantly applied keeps equipment and pipelines free of any microbiological contamination and oxygen increase (rust) and they are swept with compressed nitrogen gas for this purpose.
Bottle Cleaning and Drying
Prior to the commencement of the bottling procedure, it is important for the bottles to be clean. Before oil is filled, bottles are filled with dry and clean nitrogen to remove any gas and dusts inside the bottle. This way, oxidization reactions are prevented. After the bottles are filled, the space left at the top is filled with nitrogen gas. During storage and packaging stages, this procedure is carried out to prevent any contact with oxygen and to keep the products fresh ensuring that the shelf life is prolonged.
