    If I'm not mistaken, a food that was previously frozen degrades even faster than the same food that hasn't been frozen.

    @LaurentS.: The ice crystals destroy cell walls which makes food more soggy. Notice how bananas and other fruit loose all firmness once they’ve been frozen. I don’t think it increases the growth of harmful bacteria or mold.

    @Michael : it might. It changes the availability of water, as it's now outside cell walls, giving places for mold and bacteria to grow. Although frozen dinners would be sent through a blast chiller for quick freezing, so it's possible that there's not as much cellular damage.

  • It is a fine answer but the truth is he could probably put them in a freezer bag and keep them in the fridge for a month and be fine. These things have so many preservatives that they go bad slightly faster than honey.

    @blankip That's untrue of a lot of frozen meals. The freezing itself is the preservative in many cases.
