2. Freezing, Drying, and Canning …… Which method will you choose? Our aim: safe, high quality food. 2

3. Getting Started…Supplies Inspect jars and rims, purchase new 2-piece lids Purchase freezer containers Clean your dehydrator 3

4. Getting Started…Canners Boiling Water Canners High acid or acidified foods (pickles, salsa, fruits) Fitted with a rack Use with a tight-fitting lid 4

5. Getting Started…Canners Pressure Canners Low acid foods (meat, vegetables) Dial gauge – checked every year for accuracy, inspect gasket and vent Weighted gauge – inspect gasket and vent port Fitted with a rack 5

6. Getting Started…Produce Start with tested varieties Harvest at the proper maturity slightly under-ripe or peak of ripeness never rotten produce or produce from dead plants Discard diseased produce 6

7. Getting Started…Recipes Use ONLY up-to-date, research-tested recipes! Current canning instructions date from 1994 (or more recent) Don’t (necessarily) do what Mom told you!Don’t (necessarily) do what Mom told you! 7

8. Cold Preservation of Fresh Produce Rapidly chill leafy greens, peas and corn Avoid refrigerating cold-sensitive produce: tomatoes, cucumbers, potatoes Storing Fruits and Vegetables from the Home Garden, 2006 (A3823) 8

9. Freezing Set home freezers to 0°F or below Rapid freezing is best (smaller ice crystals & less damage) Blanching for quality, not safety! Blanching time = cooling time Proper packaging is critical for quality Freezing Fruits & Vegetables (B3278)

10. Drying Foods Air drying for herbs; Sun drying for fruits (ONLY!) Controlled drying using an oven or dehydrator is best Select a dehydrator with temperature control and a large fan Resource: www.uga.edu/nchfp/

11. Two Types of Canning Boiling Water Canning (212°F) – fruits and acid- added foods Pressure Canning (240°F or above) – meats and vegetables (dial gauge or weighted gauge canners) Remember…adjust for elevation! 11

12. How do we know which canning method to use? What is the pH (acidity) of the food? below pH 4.6 above Boiling Water Fruits, Pickles, Salsa Pressure Meat, Vegetables 12

13. Don’t harm your family with these canning methods! Boiling water canning of meats and vegetables Eliminating the canning step Dishwasher or oven canning Steam canning of meat & veggies 13

14. Tips for Successful Canning Properly pre-treat jars and lids Fill jars with hot liquid (never cold!) Leave the proper headspace Jars covered with 1-2 inches of boiling water in Boiling Water Canning Vent Pressure Canner for 10 minutes Adjust for elevation 14

15. NEW in Canning Always add acid to tomato products to ensure safety Check pickle recipes for safety Use approved recipes for salsa If jars fail to seal, reprocess within 24 hours 15

Home Canning Resources Using & Caring for a Pressure Canner(B2593) Wisconsin Safe Food Preservation Series (2008): canning fruits, salsa, vegetables, meat, tomatoes, pickles & jam (www.foodsafety.wisc.edu)www.foodsafety.wisc.edu Ball Blue Book www.freshpreserving.com/www.freshpreserving.com/ National Center for Home Food Preservation (www.uga.edu/nchfp/)www.uga.edu/nchfp/ *Resources from 1994 or later! 16

17. Don’t Forget Process at the correct temperature (boiling water or pressure canner) Follow an up-to-date, research tested recipe Adjust for elevation 17 *Note: darker areas on the state map have an elevation above 1,000 feet. Increase time when boiling water canning; increase pressure when pressure canning.

18. The RULE of Canning A sealed jar ≠ A safe jar 18

19. 5 Tips for a Successful Season 1.Start with research-tested recipes. Just because it’s in print, doesn’t mean it’s safe! 2.Use recipes that are up-to-date, from sources no older than 1994. 3.Start with equipment in good working order. 4.Leave your creativity behind. 5.Contact your local Extension office for help with food preservation questions. 19
