The University of California Master Food Preserver Program extends UC research-based information about home food safety and preservation to the public. The UC Master Food Preserver Program is a public service and outreach program under UC Sustainable Agriculture Research and Education Program (UC SAREP) within the University of California Division of Agriculture and Natural Resources (UC ANR), administered locally by participating UC Cooperative Extension county offices and a statewide online delivery program.

The UC Master Food Preserver Program is an example of an effective partnership between the UC Division and passionate volunteers. In exchange for extensive training on home food preservation from the University, UC Master Food Preservers offer volunteer services and outreach to the general public in over 37 counties. Last year, more than 500 UC Master Food Preservers donated 31,447 volunteer hours.

The UC Master Food Preserver Program’s mission is to keep Californians safe and well as they use culturally appropriate, research-based practices to safely preserve food in the home, reducing food waste, increasing food security, and providing engaging ways for Californians to explore healthy food.
