What ever the date on the can say's,
or if no date about 1 year
Home canned goods can be safely kept until the lid starts to rust or the seal is broken, but really should be used before the next harvest. Commercially canned stuff usually carries a best-by date. I wouldn't use it much past 6 months later.
Perhaps the tomatoes were no good. Perhaps you took too long to heat up the soup or reheated at too low a temperature.
Depending how you process it, berries will remain good from 6 months to idefinately.
To be ultra safe, stick to three days.
it means the tomatos are gone ofNot necessarily true. According to the Penn State Extension office:Seed Discoloration - Canned TomatoesA consumer brought in a jar of home canned tomatoes to the office (canned last year). Some, but not all of the seeds have turned black. Is there any danger in using these tomatoes? ANSWER - If the seeds began to discolor during storage, it is probably not a sign of spoilage as long as the product was processed correctly and a vacuum, indicating a tight seal, has been maintained. It may be a reaction of harmless polyphenol compounds in the seeds with iron or other minerals in the water.http://extension.psu.edu/food-safety/food-preservation/faq/seed-discoloration-canned-tomatoesAccessed January 25, 2013.
For home canned foods, figure on one year for the best quality. That should take you from harvest to harvest. Make sure the goods are properly stored - cool, dry and no sunlight:
Canned soda comes in regular and diet. The regular canned soda has about a nine month shelf life from the date it was made. Canned diet soda is good for about 3 to 4 months.
Fresh tomatoes might last a week. Home canned - about a year. Commercially canned - several years.
Canned eggs are convenient, have a long shelf life, and are a good source of protein and nutrients.
Sliced tomatoes are generally good for about 2-3 days when stored in the refrigerator in an airtight container.
Well, it depends on the condition of the tomato. Fresh tomatoes will start to deteriorate a few days after being left on a shelf. Make sure the lid on a canned tomato is completely sealed. Tomatoes are perishable. That is, their lifespan is short and they will parish very quickly. Store them in a cool place with no humidity, and they will last longer.
Homemade canned tomatoes can last for about 1 to 2 years when stored properly in a cool, dark place. However, for the best quality and flavor, it's recommended to use them within the first year. Always check for signs of spoilage, such as off smells or changes in color, before consumption. Once opened, canned tomatoes should be refrigerated and used within 5 to 7 days.
