Food processing equipment uses __________ for lubrication.

• A. Mineral oil
• B. Synthetic ester
• C. Graphite grease
• D. White grease or FGL-1

Answer: (D)

Lubrication in food-processing equipment must be food-grade and approved for incidental contact with edible products. White grease is a light-colored, food-grade grease designed for machinery that may touch food, offering good film quality, resistance to wash-downs, and easy cleanliness without contaminating products. FGL-1 stands for a Food Grade Lubricant standard, representing lubricants specifically formulated to meet safety and regulatory requirements for food environments, ensuring non-toxicity and compatibility with system materials. Other options like mineral oil or synthetic esters can be used in some contexts, but they aren’t inherently food-grade unless explicitly certified for incidental contact, and graphite grease risks leaving contaminants. So the best choice is white grease or FGL-1.
