Product Features
Food-grade white oil, also known as white mineral oil, are highly refined, odorless, tasteless, and colorless lubricants that are widely used in food processing equipment. These oils are manufactured from highly purified base oils, and their primary purpose is to provide lubrication for machinery used in the production, packaging, and distribution of food products.
Food-grade white oils must meet strict quality standards and regulations to ensure that they are safe for use in food processing applications. In the United States, the Food and Drug Administration (FDA) sets the guidelines for food-grade lubricants under the Code of Federal Regulations (CFR), Title 21. Globally, the standards are set by NSF International, which offers a certification program for food-grade lubricants under its H1 (incidental food contact) and H3 (soluble oil) categories.
Product Application
Some benefits of using food-grade white oil in food processing include:
Safety: Food-grade white oils are safe for incidental contact with food products, ensuring consumer safety and meeting regulatory requirements.
Lubrication: These oils offer excellent lubrication properties, helping to reduce friction and wear in food processing machinery, extending the equipment's life.
Compatibility: Food-grade white oils are compatible with a wide range of materials, including plastics and elastomers, making them suitable for use in various types of food processing equipment.
Stability: These oils have good thermal and oxidative stability, which helps to maintain their performance and minimize the formation of deposits in machinery over time.
Water resistance: Food-grade white oils are hydrophobic, meaning they do not readily mix with water. This property makes them suitable for use in wet environments and helps to protect machinery from corrosion.
When selecting a food-grade white oil for your food processing application, it is essential to choose one that meets the relevant regulatory requirements and is certified by a recognized organization like NSF International. Be sure to follow the manufacturer's guidelines for proper use, storage, and disposal of the lubricant, as well as perform regular maintenance on your machinery to ensure optimal performance and safety.
