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 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?
- I just inherited a pressure canner. It's pretty well used and I'm a little nervous about using it. I've never done pressure canning before. Is there a place where I can get it checked out for safety, and how do I learn how to use it.
- I just prepared pesto today containing basil, pine nuts, garlic, italian cheeses, and lemon juice, pretty much in that order from largest quantity to smallest. For how long could I keep this in my freezer before the oil will go rancid or the pesto will otherwise be inedible. Seems to me that I kept some a while back for 6 months, and after eating it I got sick, though this could be coincidental.

- I have a question regarding commercially canned tomatoes. I have read on your website that the nutritional value of vegetables may not be maintained after the expiration date. I have heard somewhere that tomatoes are an exception, and there could be a problem with the tomatoes that would not be able to be detected, and that they should just be discarded at the expiration date for safety's sake. Is this true?
