Beneficial bacteria

[Healthiswealth]

Hello everybody happy new year!!

I have a question regarding beneficial bacteria in meat and storage of meat during the week. I've been putting mine in a plastic bag and freezing it but I was thinking about beneficial dying because they are being frozen. I'm guessing the beneficial bacteria dies because they are frozen right?

Thanks

No, bacteria become dormant when frozen. They do  not get destroyed.

Oh ok cool. Thanks!

So no bacteria die? I always wondered about that. Does the meat degrade?

The ice-crystals that form after freezing apparently rupture the cell-membranes/cell-walls.This means that once the food starts being thawed, the nutrient-loss occurs  at a much faster rate.

Hmm, more info on the subject:-

Why bacteria are more resistant to freezing than animal cells:-

bacteria have a strong cell wall
- bacteria don’t have numerous internal organelles that can be damaged
- bacteria are unicellular organisms and, as such, are much better equipped to deal with extremes of temperature than, for instance, a weak differentiated specialized animal cell.
- many species of bacteria can form spores that are extremely resistant to temperature extremes
- bacteria have the advantage of huge colony numbers and fast cell division rates, so even if, say, 90% of all the cells die during a freeze-thaw cycle, the colony needs only a single survivor to re-establish itself once optimal conditions return.

Thanks for that.

There's this thing about what kind of germs are multiplying in your refrigerator as well.
I would not depend on those beneficial bacteria.
Better you really get fermented stuff to make a lot lot more good bacteria.

I am making some high pork now.

The best method I have found has been to dedicate an entire fridge to open hang large pieces for dry aging.

I have a freezer unit that has a thermostat bypass so I can manually set the temperature, which I typically keep a couple degrees above freezing.
