Hi All,
I maybe late sharing this idea or breaking new ground with it.
We just very successfully "cryovaced" some cooked meals (for a 6 week trip north) by putting the meal in the plastic meat tray in which the meat was sold, putting that in a suitably sized zip top bag. Zip the bag almost closed from each end towards the middle somewhere and insert a plastic drinking straw so the end is in clear space. Pinch down on each side of the straw on the zip but do not flatten the straw. Suck hard to remove as much air as you can, block the straw with your tongue and remove the straw quickly and close the zip lock. BINGO!! Works like a charm.
Now, does that get hotted or get knotted?

Don't think "suck dried meals" will ever be a commercial success

You would be bleeding from the ears before you got down to anything like the vacuum that you get from even a basic vacuum packing machine!

Hi Ian,

The aim of successful vacuum packing is to remove all the air from the pack. A perfect vacuum of -1.0 Bar would be ideal but impossible to attain in practice. A good machine would achieve -0.8 Bar before retaining that pressure by sealing the package. Most commercial machines achieve -0.9 Bar.

By using your mouth to suck the air you may attain -0.1 Bar at the most which would be quite inadequate removal of the air to achieve any degree of preservation.

If you relied on this method you risk contracting food poisoning.

Sorry to destroy your great idea mate.

Cheers
Allan

I agree with Allan and definitely don't use fish or chicken done your way.

Bigfish .. I had limited success using a bicycle pump with a soccer ball attachment. I did it as an experiment prior to a trip. I only used it on meat, which I had removed from its packing and put into a sealable bag. The meat was kept refrigerated and we ate it a couple of weeks later. But having said that, I am not able to say just how effective that method was, but the meat was good.

Nothing wrong with using ziplock bags for some meal food preps.
Not as good and won't last as long as cryo vac seal machine prepared, but for up to 2 weeks I have found it is totally reliable for our trips.

We don't keep the meat trays, just the meat directly in the bags.

I have a vacuum cryo machine, and because most of my trips are 2 weeks or less, usually just use the ziplocks.
I just cut up meats into strips or whatever is desired, spray some olive oil in there for frying up, roll it up nice and tight, getting as much air out as possible, then double bag in another ziplock.
Freeze. WELL.
I do this a week or more before a trip to get very deep frozen, pack around edge of car fridge compartment at -2, beer etc in the middle.
I need to defrost meats a day before using, right up to the last days of a 2 weeker.

We tend to keep a couple of red meat packs for the end period, using chicken first, though I did a Simmo trip in May, ex Brisvegas, my brother and I had chicken dish at Parachilna Gorge in the Flinders on the way back to Adelaide afterwards, some 2 weeks after we left BNE.

The emptied ziplock bags are then reused for 'wet' rubbish, like the inside meat bags, tea bags, etc.

The idea is great but as some have said, not really effective as a cryovac type process. Please don't be put off by the negative replies, sharing ideas is one of the great features of this place.

Hey Whirlwinder


I'd wait a couple weeks before you hit people with your next idea -

"Solar Powered Cigarette Lighters "



All the best

While the solar powered ciggy lighter is a great invention, it is targeting a falling market.
Much better to get into renewables, and come up with something like the battery powered battery charger :D

May I suggest you not recycle used meat trays to store cooked food. Not sure whether you can entirely avoid cross contamination and the discomfort that may follow!!

Folks, something not to overlooked - Quite apart from the very very doubtful control of bacteria, the registered holders of the c...vac name have a serious reputation for protecting their intellectual property. I think they'd be very cross about the suggestion that their process could be matched using a drinking straw and a ziplock bag!

That is a correct and valid comment.
Cryovac is a trade name for "vaccuum sealed" product. We use a commercial vaccuum packing machine, and commercial grade bags for our produce. Our olives are marinated and packed with marinade. They will keep for months like that.

We also use the machine to pack food for travel, and for sous vide cooking. The fact that it can get all (or bloody near all) of the air out of the bag is the big benefit over the Aldi and other el-cheapo vaccuum packing units.

Obviously, we use what we've got. and in the van we'd not have the space or weight allowance for the commercial unit, and we'd have to revert to the smaller one. Will have to see how that works!

Whirlwinder.
Is your surname Hoover by any chance. Even they only suck a little bit. Just because the eardrums feel a negative pressure it hardly constitutes a Vacuum.

I thought April 1st was earlier.

Using a straw is no good. Too much internal resistance to airflow to achieve a good enough "suck".

Us a short length of garden hose instead. More suckability there straight away. Ask any home made bong maker!

Standard practice for every package I freeze....gets most of the air out so I get smallest size package and no condensation crystals. Just use a shot length of rubber trickle irrigation hose.....and freeze bread overnight first so you don't squash it flat.
