The differences between food-grade grease and standard industrial grease used in food production facilities are critically important for both food safety and performance. Here is a detailed explanation:
1. Definition
| Type | Definition |
|---|---|
| Food Grade Grease | Non-toxic grease formulated for use in machinery that may come into contact with food, NSF H1 or FDA approved. |
| Standard Grease | Grease produced for general industrial use, not certified safe for food contact. |
2. Food Safety
- Food grade grease: When it comes into contact with food, it leaves no harmful residues, and does not affect taste or odor. Complies with HACCP and FDA standards.
- Standard grease: When it comes into contact with food, it can be poisonous or toxic, posing a risk of contamination.
3. Areas of Use
| Grease Type | Area of Use |
|---|---|
| Food grade grease | Areas with a risk of food contact, such as filling, packaging, ovens, chains, bearings, and sealed machinery. |
| Standard grease | Motors, pumps, general mechanical equipment in factories, areas without a direct risk of food contact. |
4. Chemical and Physical Properties
-
Food grade grease:
- Contains NSF H1/FDA compliant additives
- Temperature and load resistance are optimized according to equipment requirements
- Resistant to water, steam, and cleaning chemicals
-
Standard grease:
- Can withstand high pressure and temperature but is not safe for food contact
- May generally contain heavy metals or toxic additives
5. Price and Supply
- Food grade grease is generally more expensive because its formulation complies with food safety standards.
- Standard grease is cheaper, but its use in food production lines is risky.
