Nitrogen purge system DONE
The cost of filling the cylinder was $26 for Nitrogen, and if I'd
opted for Argon, the cost would have been just under $50. FWIW, the cylinder I bought for around $68 on eBay was 40cf. When I took it to the compressed gas guys, they offered to either fill my own cylinder, or let me just "exchange" it for a 53cf one already filled and for the same price. I asked about what a new 53 would have cost if I'd just walked in, and it was $160, so I got a good deal, so to speak. Once back home with the filled 53cf cylinder, I hit Harbor Freight and bought a 25', 3/8", compressed air line. By cutting one end off, I fit the barbed fitting on the pressure regulator and the other end screwed nicely into the air blow gun I got at Harbor Freight while getting the line. I went behind the refrigerator and drilled into the wall, coming out in the spare bedroom behind the kitchen. It was perfect, in that the cylinder was thus between the end of a dresser and the wall- hidden but very accessible. I snake the line to behind the refrigerator, where it now sits self-coiled. I set the pressure regulator to 15psi and that seemed about right to blow in nitrogen, without blowing out liquids or dry things from a baggie. Tonight, we had bean soup and I put the remainder into two 2-qt. Tupperware containers. Just before sealing the lid, I gave each a brief squirt of Nitrogen to keep them fresher in the refrigerator. Once I've used up this first fill of Nitrogen, I find that they'll "blend" nitrogen and argon in the bottle for me at the blended price. That'd give me another gas in the mix, but one a tad heavier than O2 and able to sit on top of liquids better. At my expected rate of usage, that should be somewhere in about 2012 or so- after the Apocalypse. -- Nonny Luxury cars now offer a great seating option for politicians.

I'm no expert, Steve, so my opinion is not worth too much. What I want is two ways to retain freshness- the Foodsaver is like you suggest, in that you remove almost all the air and store foods in a freezer inside a bag that virtually eliminates moisture or air exchange with the outside world. That's great, IMHO, for most meat and even prepared foods that have been prefrozen so that the liquids won't mess up the vacuum. IMHO, though, the Foodsaver bags and their "resealability" present some issues. I've experimented successfully vacuum sealing regular zip-lock type bags, but it still takes time and isn't perfect in the least. What I'm wanting is the ability to NOT have to vacuum a zip-lock type bag, but still exclude oxygen. I'd say a prime example would be a 1# bag of shredded cheese in the refrigerator. I used some tonight and after removing what I wanted, I pressed the bag slightly to push out a lot of the air, then inserted the nozzle of the nitrogen gun into an opening in the zip lock zipper and gave it a squirt. The bag "inflated" with the nitrogen gas, which I then again pressed out some and finished zipping it closed. I also did that with some Tupperware quart containers of bean soup I had, before freezing. I'd not consider the time or expense of freezing half of a leftover sandwich, but just toss it into a baggie and put on a shelf in the refrigerator. With the nitrogen puffer, I can exclude most of the oxygen in the air, giving the sandwich a longer shelf life. OTOH, when I cook 5 breaded tenderloins for sandwiches tomorrow, we'll eat 2 and freeze up the remaining 3. Those will be done in Foodsaver freezer fashion, since I'm sure it'll have a longer life. I MIGHT try a purge with the nitrogen before vacuuming, but might not, either. What I think of with the nitrogen system is an intermediary step between just bagging and refrigerating something and the ultimate storage of vacuum/Foodsaver/freeze. -- Nonny Luxury cars now offer a great seating option for politicians.

As the long-suffering Mrs. Nonny says, "You just gotta' understand." She and I met before kindergarten and during the first grade, she'd beat me up after school. Finally another friend asked her to "Please don't kill Nonny, because he's a nice boy." Since then, there's been a kind of "peace" between us and has lasted for most of our 43 years of marriage. She's suffered through many of my adventures, such as building a boiler in our fireplace so we could heat the house with firewood, a heat reclamation gizmo that looked like a canon I used to blow excess heat into a room I'd built, a solar panel that traveled clear across our neighborhood during a storm, a Jim Beams dispenser in my '57 Ford for when we were dating, other things I'd done to cars that just can't be described, lawn care equipment that could have gotten me arrested in several states, security and other electronics that would have done NASA proud, cooking devices that should be registered as lethal weapons and a number of even more bizarre things. Nope, Marty, a hole in her cabinet and the wall, coupled with a 55cf cylinder and regulator beside a dresser ain't nothin' compared to what that poor woman's seen and lived with in the past. -- Nonny Luxury cars now offer a great seating option for politicians.

While it can be deadly, it has to be in certain concentrations. Monoxide is used in places you'd not expect. http://en.wikipedia.org/wiki/Carbon_monoxide Meat coloring Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat products such as beef, pork, and fish to keep them looking fresh. The carbon monoxide combines with myoglobin to form carboxymyoglobin, a bright cherry red pigment. Carboxymyoglobin is more stable than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown pigment, metmyoglobin. This stable red color can persist much longer than in normally packaged meat.[31] Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%. The technology was first given "generally recognized as safe" (GRAS) status by the U.S. Food and Drug Administration (FDA) in 2002 for use as a secondary packaging system, and does not require labeling. In 2004 the FDA approved CO as primary packaging method, declaring that CO does not mask spoilage odor.[32] Despite this ruling, the process remains controversial for fears that it masks spoilage.[33] In 2007 a bill[34] was introduced to the United States House of Representatives to label modified atmosphere carbon monoxide packaging as a color additive, but the bill died in subcommittee. The process is banned in many other countries, including Canada, Japan, Singapore and the European Union.[35][36][37] |

NOW I understand where you're "coming from". I'll be interested in hearing results of things like the 1/2 sandwich experiment. My experience in trying to save 1/2 sandwiches in baggies in the fridge is that they get soggy. Don't know if the nit. would help that or not. -- Steve |

I took sliced bananas that I was going to use to garnish some banana creme brulee, divided into three containers, one control with nothing but a lid, one with acidulated water, and one nitrogen purged. Several hours later, the control was pretty discolored and ugly, the acidulated water one wasn't discolored, but it was mushy, and the nitrogen one looked pretty much the same as when I packed it. |

The half of a banana left over from my oatmeal <shudder> for breakfast is enjoying a nitrogen bath. So far, it looks good as new. We had breaded pork tenderloin sandwiches tonight for supper. While I Foodsavered most of the batch, the two "half" sandwiches left over are nitrogened and in the refrigerator awaiting breakfast call tomorrow AM. Over a short period like that, I don't really expect any improvement or degredation. However, it's fun to play with the new toy. Mrs. Nonny's <shudder> whole wheat bread is nitrogen purged as well. -- Nonny Luxury cars now offer a great seating option for politicians.

A word of caution with the liquid gases. They will evaporate at a pretty constant rate, so if your demands aren't high, you'll be wasting money. Second they will be releasing cold gases than can easily displace oxygen from a room, from the floor up. This can lead to unconsciousness and death. And carbon monoxide is used to kill fish in water, and keep their meat with an attractive color. So though it is dangerous to work with / be around, and it provides little antibiotic protection, it is not unknown to flood foods with it. David A. Smith |

Man... talk about > paranoid... Dewars of liquid nitrogen are NOT available in that package. Or that package weighs tons, and has foot thick walls. Please keep your eye on the ball. People have been killed by being unaware of consequences of "saving a buck", or "playing with cool stuff". Like talking to a bunch of know-it-all four year olds... David A. Smith |

Smith > > Hello... it's in a sealed pressurized tank with a safety flow regulator > on it.... Man... talk about paranoid... Actually, he was referring to my LN2 Dewar on part of that. Yes, liquid nitrogen does have a finite hold time in a Dewar (100 day static hold time on my 25L Dewar), so you need to use it or loose it as it continues to slowly boil off and vent through the pressure relief valve. Compressed nitrogen gas in a cylinder has essentially infinite hold time. Yes the vented nitrogen can displace air/Oxygen if the Dewar is in an enclosed space. Mine sits in the corner of my Kitchen most times and with there is plenty of both room volume and air movement to prevent any accumulation of a low hanging nitrogen layer. |
