The UC Master Food Preserver Program is open to individuals looking to increase community knowledge in home food preservation methods. Applicants for the UC Master Food Preserver Program must be willing to share knowledge and skills learned from certification training through local community outreach. Prior food preservation knowledge is not a requirement; willingness to teach others is.

Examples of community outreach from UC Master Food Preservers:  

  • Classes and workshops
  • Hands-on demonstrations 
  • County fairs 
  • Websites and blogs
  • Print and digital media

How UC Master Food Preservers make a difference:

  • Teach safe and food preservation methods in local communities 
  • Share knowledge about preserving fresh and healthy produce 
  • Prevent botulism in home canning 
  • Promote research-based methods of food handling and food preparation
