How did a simple question on roe turned into a chemistry lesson ?

How did a simple question on roe turned into a chemistry lesson ?

Probably due to a lack of wanting to do any real work.  and that there are not any shopes like this around: http://www.youtube.com/watch?v=teMlv3ripSM

work2fish, I must not be conveying my message clearly. First of all I am not claiming the chemical reaction is what causes the pressure change nor did I ever claim it did. I was pointing out it was the removal of oxygen (through combustion) that helps prevent freezer burn, since freezer burn is the oxidization of fats and proteins in the roe.

Secondly my point is that by lighting a candle you do NOT instantaneously make the entire area around it 1000 Degrees. It's a heat transport problem. The AVERAGE temperature once the lid is sealed will not be a thousand degrees. It will be far from that. You must not of read the part were i said "an inch away from the flame." You can't honestly believe that in the time it takes for a match to burn an inch that it would be enough time for the entire area at the mouth of the lid to reach an equilibrium temperature of a 1000 degrees?

The example you provided does not relate. Neither an egg nor a water balloon will form a tight seal around the lid of the jar (it's in the answer. I peaked) and therefor it is not a closed system. Our jar lid does form a tight seal and can be considered a closed system.

And if you really need to belittle me to try and prove your point you must slowly be realizing that you are wrong and that the only way out is either to admit you are wrong or try and make me look stupid. Nice Try.

You never said anything about freezer burn.  What you did say was "Actually you are not creating a vacuum seal when you burn paper or a match in your roe before you put the lid on. All you are doing is removing the oxygen through combustion and turning it into CO2 and Water. "

And I didn't say it "instantanously" heated the air to 1000C, nor does it need to be 1000c to create a vacuum.

Actualy it does, in that it relates to creating a vacuum in the bottle.  By heating the air in the bottle, then creating a seal with the egg, as the air cools it creates a small vacuum presure.   

And if you really need to belittle me to try and prove your point you must slowly be realizing that you are wrong and that the only way out is either to admit you are wrong or try and make me look stupid. Nice Try.

Naw, not trying to belittle you, or make you look stupid, you've doing a fine job of that yourself.

I don't want to have to explain every line I type to you. So I'm leaving it as is. You believe what you want and I'll believe what I think is right.

try storing it in glass canning jars. I have kept roe 4-5 yeares with no problem. Burn a small peice of paper when putting the lid on it. You can get a dozen jars for about $10.00 at Save on or CTC.

I use this method as well and it's an excellent way to freeze roe.  I buy used jars from MCC and other Christian second hand outlets for $1 to $2 a dozen. Even though the jars are used they look new and since I am using them for freezing roe and keeping gardening seeds I don't need to use brand new jars. You can get them in different sizes as well. There are many stores like this in the Fraser Valley.

im lost but thanks for all the advice
