Information about lubricants for food and beverage industry
Composition of food grade lubricants
Lubricants used in the production and packing of food and beverages must not have any negative impact on the product quality, i.e. consumption and consumer health shall not be impaired. Therefore they are not only required to be faultless concerning foodstuff regulations but also taste- and odourless and free of any risk for the consumers’ health. In order to classify lubricants with regard to food regulations, national stipulations, as for instance the German Foodstuffs and Commodity Act, and internationally accepted standards, such as the Food Safety Modernization Act (FSMA), Hazard Analysis and Critical Control Points (HACCP), ISO 21469 and registration with the NSF (National Sanitation Foundation), are decisive. Global companies should also obtain FSSC 22000 certification (Food Safety System Certification) with approval from the GFSI (Global Food Safety Initiative). A certification as kosher and halal is also becoming more and more important.
The US has and always had the strictest requirements as regards the classification of raw materials for food compatibility. Therefore, the American standards are groundbreaking for the composition of a lubricant according to food standards. The special feature of food-grade lubricants is that only basic raw materials may be used, which have received approval from the FDA (Food and Drug Administration). All approved substances and regulations are listed in list 21 CFR § 178.3570.
Not suitable for the production of lubricants for food production are:
- Aromatic mineral oils
- Heavy metal-containing additives (e.g., ZDDP - zinc dialkyl dithiophosphate)
The responsible production of food-grade lubricants in production plants requires certification in accordance with ISO 9001/14001 and ISO 21469. The basis for this are high-purity pharmaceutical-grade white oils and state-of-the-art synthetic base oils. Thanks to intensive research, food lubricants from ADDINOL are just as powerful as synthetic lubricants without food suitability.
Requirements for food-grade lubricants
Food industry places particularly high technical requirements on the lubricants. Maximum capacity utilisation, ever shortened downtimes, in part extreme temperatures and often aggressive ambient conditions – these challenges can only be met by high-performance lubricants.
Properties of food-grade lubricants are:
- NSF-H1 certification and registered in the NSF White Book
- certified as kosher and halal
- reliable protection of the components against friction, wear and corrosion
- best ageing stability for long operating lives
- resistant against aggressive ambient conditions
- outstanding temperature stability
- high compatibility with materials, sealings and paints
- very good heat dissipation
The food, beverage and pharmaceutical industries in particular must pay attention to issues such as hygiene and the quality of their products in order to be successful in the long term. A good reputation is very important in the market. High losses of money, lawsuits or recalls are possible, if complaints arise about the compatibility of the products. Therefore, the food lubricants must match the highest standards of health safety.
Applications of food lubricants
Machines in the food industry are basically similar to those from other industries. There are sliding and rolling bearings, chains, compressors, gears, hydraulics and pumps that need to be lubricated. However, the lubricants often have to cope with much more extreme conditions than in other industries. This is due to high temperature differences, changing humidity and entry of acidic and basic liquids in the production process.
Food lubricants are used in a wide variety of industrial plants. These include:
- baking industry
- confectionery industry
- meat industry
- fish industry
- animal feed industry
- beverage industry
- fruit and vegetable industry
- dairy industry
- pharmaceutical industry
- cosmetics industry
- tobacco industry
Changing intervals of food lubricants
The environmental influences in food production can be very complex. When an oil or grease needs to be changed in a machine depends greatly on the application and the environmental conditions. The oil change intervals depend heavily on the contamination of the lubricant in addition to the ageing of the oil due to oxidation or used additives. You should regularly take a sample of the lubricant and send it to appropriate laboratories. Our experts in application technology will be pleased to advise you.
Certifications and approvals
Currently, the certification of the American NSF (National Sanitation Foundation) is the most important classification of food grade lubricants worldwide. The American board FDA (Food and Drug Administration) defines which components are allowed to be used for these. 21 CFR § 178.3570 lists all permitted raw materials by their exact chemical names and quantities. The list cites components only which do not pose any health hazard (physiologically harmless) according to the actual state of knowledge and have been tested in comprehensive toxicological analyses. The NSF judges the finished lubricants and lists the products certified in the White Book.
The USDA (United States Department of Agriculture) independently approved food grade lubricants before NSF. From October 1, 1998 this responsibility was taken over by the NSF.
The Hazard Analysis and Critical Control Point concept identifies and eliminates food hazards. All processes of food production are illuminated, i.a. production, processing, transport, storage and sale. Food companies conduct internal HACCP controls to improve their own standards. It identifies health hazards from chemical, physical or biological sources to take preventive action. All harmful influences on the production process of food should be avoided as much as possible. This means, contact between maintenance lubricants and the end product must be kept at a minimum level. If that is the case, the lubricant must at least be harmless to humans and animals.
The principles according to HACCP are:
- carry out hazard analysis
- define critical control points
- determine limit values
- systematically monitor critical control points
- take countermeasures if limits at a control point are exceeded
- verify the success of the HACCP system
- document all procedures and measures
ADDINOL has been certified to ISO 21469 and fulfills the requirements of the HACCP system. ISO 21469 specifies standards and hygiene requirements for the composition, production and use of special lubricants. This includes lubricants for use in machinery of the food, cosmetics, pharmaceutical, feed and tobacco industries.
Kosher approval of food lubricants is subject to compliance with Jewish dietary regulations. The lubricant itself must comply with the dietary regulations. We guarantee that the lubricant contains no animal ingredients. The lubricants can be used both in the production of milky and meaty foods. This is called “parve”. The kosher certificate is renewed annually by a rabbi.
The halal approval requires the production of food according to the Islamic dietary regulations. Lubricants used in the production of halal products are also subject to these regulations. To ensure this, we do not use any animal products in the manufacture of our lubricants. In addition, all food lubricants are without ethanol. This means, they are alcohol-free. Halal approval is granted annually by Halal Control.
