Ketchup seems to go bad really quick outside the refrigerator.  I opened up a packet and I found that the bright red color had dulled.  I didn't eat it, so I don't know if it was really "bad" or not.  Does someone know if that color change is acceptable or edible or whatever applies? Does anyone have a list of the shelf lives of these packets outside the refrigerator?  I don't have enough space inside the fridge for 5 pounds of condiments.  Soy sauce sure seems to last a long time, though.
Thank you
