- grains
- flour
- sugar
- powdered products
21 CFR 177.2600
This regulation covers rubber articles intended for repeated contact with aqueous foods and food products containing limited alcohol content.
For food processing applications, polyurethane components must maintain stable properties after repeated exposure to:
