Unless you know the code system that the processor uses, you will have to open the can.
I would strongly suggest that you don't. Canned food is susceptible to many pathogens. If in doubt, throw it out.
I would highly recommend dry food as it has more calories than canned food. Canned food has a lot of water in it, read the label. You could also mix a little canned food in with the dry food too. I prefer the dry food only. Be sure to feed a good name brand dog food, not some cheap generic dog food. Read the label, should NOT have meat "by products", soy, wheat, corn, beet pulp, etc. in it. You want to see things like Chicken meal (or whatever type of meat it is) & not Chicken by products. "By products" contain the worst parts of the meat, such as hooves, horns, beaks, talons, etc.
Canned food can be good for a year or more. If it is ruined, the gases inside the can will cause the can to bulge.
Yes, canned food can explode in a fire due to the buildup of pressure inside the can as the contents heat up. When the temperature rises, the gases inside expand, and if the pressure exceeds the can's structural integrity, it can rupture violently. It's important to keep canned goods away from open flames and extreme heat to prevent such accidents.
Nothing canned can be frozen as the water inside will freeze and expand squashing the potatoes. Canned food can last for years so you don't need to freeze them.
No. Freezing canned goods will expand the material inside and split the can open. Food is canned to preserve it . . . you could simply store it on the shelf in a cool place.
caned food must be sterile.No bacteria its founded inside the canne.
There is no magic date. It will depend on the quality of the food to begin with, the quality and type of container and the subsequent handling and storage thereof. Even canned, food will degrade and change color, texture and flavor. I have used some items that were a year past the coded date. They were edible, but I could tell the difference when compared to newer product. Many canned foods are coded with 2 and even 3 year shelf lives. But for best quality and nutrition, plan to use canned goods within a year. If you are trying to maintain a cache of canned foods, use product throughout the year and replace it with fresh stock. Use the FIFO method - First In First Out. Always use the oldest items first.
Yes, you can put canned food in the fridge.
If serving sizes are given, they are normally on the "nutritional information" label - it will break it down into an analysis per 100g, and then per portion. However not all canned foods state serving sizes.
There are many places that you could sell canned food in mason jars. You could sell this canned food in your yard for example.
The Canned Food Information Council was formed in 1986
