ELBAFOOD 680 GH-1 FOOD GRADE GEAR OIL NSF REGISTERED AS H-1 OIL.Food grade lubricants can be based on white mineral oil or certain synthetic fluids, and are used in the food and beverage processing industry. The food grade lubricant must serve all the regular functions of lubrication, but it must also adhere to strict guidelines. These lubricants must also withstand the degradation that can occur with contact with food products, juices and sugar solutions, water, steam, and cleaning chemicals. Food grade oils are also inert, have no taste or odor, and meet stringent government standards.
Food grade lubricants come in four categories — H1, H2, H3, and 3H. H1 lubricants are used in equipment that comes into direct contact with the food. Only incidental contact of the lubricant with food is allowed. H2 lubricants are used in locations where the equipment does not come into contact with food and there is no possibility of contact.
