Does my stored food still have any nutritional value?
Rate This FAQ
Nutrients in food are affected by exposure to heat, light, and air. There are many nutrients to consider in stored foods. Following are some effects of storage on some nutrients:
· Calories - foods continue to provide needed energy over time
· Minerals - very little change in stored foods
· Carbohydrates - very little change in stored foods
· Proteins - change in reaction in recipe; for example old wheat flour will not rise, because the proteins are unable to form gluten
· Fats - oxidation (become rancid) creates off flavors and odors
· Vitamins - some loss over time; destroyed by heat, light, and oxidation. Storing and eating a variety of foods can assure adequate vitamin intake.
Rotate stored food within 2 to 3 years to maintain optimal nutritional value.

- I grew up eating green beans which were pressure-canned at home. When my mother heated them for a meal, she brought them to a boil then removed the lid and let them boil for at least a minute with the lid off. She said this was necessary to be safe. Is it necessary or was that just something passed down from before pressure canning was available?

- I have a question about my pressure canned sliced peaches. I cold-packed sliced peaches covering them with a light syrup. Following instructions I packed them with 1/2 inch headspace and poured the liquid to 1/2 inch headspace. However, the peaches floated up so that they were not covered by the liquid during processing. I did run a wooden spatula down the sides of the jars and seemed to get all air bubbles out of the jar. I processed in the pressure canner according to instructions at 10 PSI for 10 minutes. When I removed the jars the liquid was boiling and there seemed to be a lot of air bubbles around the fruit. The jars were already sealed when I took them out of the canner after waiting 10 minutes after the pressure seal dropped. The liquid is down considerably - looks to be about 1 1/2 to 2 inches and the peaches are floating. There are air bubbles and air pockets. The seal is fine. Are these peaches safe?

However, after taking out the jars I noticed that filling had bubbled up out of the jars during processing. The lids seem sealed, but how can I be sure they are safe? Should I have left a larger headspace than 1 inch???
