Home Food Preservation

Introduction

Home food preservation can help make fruits, vegetables and other foods last longer. After having your pressure gauge tested, visit one of the many Farmers Markets or farm stands in our region and start preserving fresh food from local farms.

It is recommended that your dial gauge be tested for accuracy before each canning season begins. The dial gauge can be tested free of charge at the Yakima County Extension office. Drop off the lid and gauge at our office any time between 8:30 am – 4:00 pm. The office is closed from 12:00 pm – 1:00 pm. Call ahead at 509-574-1600 to see if the tester is available. Keep in mind it might take up to 2 days for testing.

Food Preservation Online Course – Under Construction

WSU Extension is developing a program to replace the previous “Preserve the Taste of Summer” Online course. Once information is available, it will be posted here.

Food Safety Questions

If you have questions about food safety or preservation, please call our office at 509-574-1600. Keep in mind that you might not receive an immediate response, but our Master Food Preserver volunteer will return your call. You can also try reaching the Benton/Franklin Master Food Preservers at 509-735-3551.

The National Center for Home Food Preservation is your source for current research-based recommendations for most methods of home food preservation. The Center was established with funding from the Cooperative State Research, Education and Extension Service, U.S. Department of Agriculture (CSREES-USDA) to address food safety concerns for those who practice and teach home food preservation and processing methods.

Understanding Processing Times for  Home-Canned Foods

Canning is an exact science. Safety depends in using research based recipes, precise measurements of ingredients, clean work environments and exact timing when it comes to the processing procedures.

Pressure Canner Types

There are two types of pressure canners – dial guage and weighted gauge.

Dial gauge canners have a sensitive pressure gauge used to measure the internal pressure of the canner. Over time, as the canner lid is handled, bumped, or just used, the calibration of a dial gauge can become inaccurate. Even gauges on new canners and replacement gauges need to be tested before use.

Weighted gauges do not need to be tested. Just make sure to check rubber seals and safety plugs regularly for wear and replace when necessary

If the dial gauge on your pressure canner does not register correctly, you could be jeopardizing the safety of the food you preserve. To avoid any issues with the proper function of your pressure canner, you should have it checked.

The USDA recommends having pressure canner dial gauges tested annually.

Canning in Electric Pressure Cookers

Electric Pressure Cookers are being advertised as an acceptable way to process home canned foods. Should I can in my electric pressure-cooker appliance?

Canning on Smooth-Top Stoves

A common question that arises during canning season is whether or not you can use a smooth cooktop for canning. Because of the variability in types of smooth cooktops, there is no simple answer. This fact sheet will help explain the issues and concerns with canning on a smooth cooktop.

Introduction to Food Dehydration – University of Missouri Extension

Dehydration is one of the oldest methods of food preservation, though methods for drying food have become sophisticated over time.

This guide covers different drying methods and the basic temperatures and conditions needed to safely dry food.

USDA Jerky and Food Safety

When raw meat or poultry is dehydrated at home — either in a warm oven or a food dehydrator — to make jerky which will be stored on the shelf, pathogenic bacteria are likely to survive the dry heat of a warm oven and especially the 130 to 140 °F of a food dehydrator. Included here is the scientific background behind drying food to make it safe and the safest procedure to follow when making homemade jerky.

USDA Smoking Meat and Poultry

Where there’s smoke, there’s well-flavored meat and poultry. Using a smoker is one method of imparting natural smoke flavor to large cuts of meat, whole poultry, and turkey breasts. This slow cooking technique keeps them tender, too.
