Food and Beverage Lubrication from Lubriplate — the Pure, Safe Approach

Food and Beverage Lubrication from Lubriplate — the Pure, Safe Approach

Food grade lubricants have been a part of industrial lubrication since the early 1960s. They were first introduced and used in the United States market. Since their initial development, there have been great high technological advancements with research, development, introduction and use of food and beverage lubrication.

Early Development and Monitoring of Food Grade Lubricants

Title 21 of the Food and Drug Administration’s (FDA) Code of Federal Regulations (CFR) presents many sections which authorize ingredients that may be used to produce food grade lubricants. There is a chart accompanying this article which displays the sections in the FDA’s Title 21 and presents brief descriptions of some of the more popular ingredients used by lubricant manufacturers to produce their food grade lubricants.

In the early 1960s, the Food Safety and Inspection Service of the U.S. Department of Agriculture (USDA) committed to monitoring and authorizing lubricants which could be used to lubricate machinery which had incidental contact with the food. This became known as the USDA/FSIS “Prior Approval Program for Non-food Compounds and Proprietary Substances.”

PiesConveyorThe FSIS published its “White Book,” which listed lubricants that have been authorized as “H-1”—which means they were authorized for use in federally inspected meat and poultry plants for incidental contact with food product. The FSIS’s authorization process and program was based on the FDA’s Title 21 list of approved ingredients. This program for authorization of food grade lubricants quickly spread, and was recognized by food, beverage, and pharmaceutical processors throughout the world.

But, the authorization and monitoring program of the food and beverage lubrication industry changed drastically in 1998 when the USDA/FSIS eliminated its “Prior Approval Program” and “White Book” authorization program for non-food compounds. Was the lubricants industry to engage in self-monitoring for H-1/food grade lubricants? Or would a third-party professional monitoring organization step forward and adopt a food grade lubricants’ monitoring program?

NSF, ISO, and HACCP Standards for Food Grade Lubrication

The National Sanitation Foundation (NSF), based in Ann Arbor, Michigan, stepped forward and produced an industry authorization and monitoring program which closely mirrored the former USDA/FSIS program. The worldwide lubricants industry quickly committed to the NSF’s program, and today, the NSF is the leader is authorizing and monitoring H-1/food grade lubricants for all lubricants manufacturers. NSF H-1 authorized food grade lubricants are posted on the NSF’s website.

NSF-OU-M-ISO-LogosThe International Organization for Standardization (ISO) also developed the ISO-21469 certification and registration process for lubricants used in specialized industries such as food, pharmaceuticals, cosmetics, animal feed manufacturing. This is a very stringent standard and registration process in which lubricants manufacturers must first be registered and maintain the ISO-9001 Quality Management standard which demonstrates the commitment to an overall Quality Management System.

LubrpltPlantSurveyFinally, H-1/food grade lubricants also are part of Hazard Analysis & Critical Control Points programs (HACCP.) In the U.S., the FDA and the USDA demand that food and beverage processors develop HACCP programs in which lubricants may be considered as potential chemical hazards. However, if food and beverage processors switch to 100% H-1/food grade lubrication programs, then lubricants are not considered potential chemical hazards and a HAACP plan is not necessary for a 100% H-1/food grade lubrication program.

Food and beverage lubrication suppliers should be aware of all industry standards which affect H-1/food grade lubricants. Food grade lubricants packaging and literature should clearly define the product and relate to all of these industry standards. Consumers must watch for unscrupulous and confusing claims on packaging and in product literature.

New Technologies in Food Grade Lubricants

In the 1960s, there were not many fluid-based stocks, additives or grease thickeners available which were listed in the FDA’s Title 21 CFR sections. This resulted in poor performance of H-1/food grade lubricants.

However, technological advancements have changed the availability of H-1/food grade lubricants. In 2014, H-1/food grade lubricants can accommodate every application on machinery in food, beverage and pharmaceutical processing facilities from refrigeration compressors, to freezer conveyor chains, to gear boxes to filling, seaming and closing equipment.

BearingSynXFG2For example, in the early 1960s, it was impossible to find an H-1/food grade grease which delivered both anti-wear and extreme pressure protection. Today, calcium sulphonate thickened greases made with USP white mineral oils and synthetic polyalphaolefin (PAO) base stocks are truly anti-wear and extreme pressure lubricants.

Lubricant manufacturers have also been able to add anti-microbial additives to their products. Anti-microbial additives help to prevent the decomposition of lubricants caused by microorganisms. Many anti-microbial additives are registered with the U.S. Environmental Protection Agency (EPA).

The use of synthetic polyalkylene glycol (PAG) base stocks to manufacture H-1/food grade gear oils has produced H-1/food grade gears oils which deliver extended drain intervals and unmatched anti-wear and extreme pressure protection. Gear reducer original equipment manufacturers (OEMs) now have no fear in recommended H-1/food grade synthetic PAG-based gear oils.

Synthetic polyol ester (POE) food grade fluid technology now delivers optimum lubrication protection for high heat oven chains in bakeries. POEs have unmatched oxidation stability which virtually eliminates carbon deposits and keeps the chains clean.LubrpltH1ProductsPhoto

Silicones and PTFE are also used very effectively as H-1/food grade lubricants.

Synthetic H-1/food grade technology also helps to consolidate the amount of lubricants required. For example, synthetic PAOs work very effectively in both air compressors and hydraulic systems. It is very possible to use the same ISO-46 fluid for both air compressors and hydraulic systems.

Why Convert to an H-1 Food Grade Lubricant?

All of these technological advancements in H-1/food grade lubricants mean that food, beverage, and pharmaceutical processors should not hesitate to convert to a 100% H-1/food grade lubrication program. Converting to 100% H-1/food grade program delivers money-saving lubricants consolidation, a reduction in lubricants misapplication, sustainability and helps to ensure a safe product for the ultimate consumer.
