Industrial chemistry Food preservatives

Posted by: @amalgama

What are the latest trends in food preservatives? I've heard that long ago laughing gas was used for the role, but industry probably evolved since then

Laughing gas is only used today in cream cake cans. By the way, I wonder why he is there too? In general, sodium benzoate, sodium aspartate, sodium nitrite are often used.

@argentum _{I think it's industrialy convenient compound that both exist in gaseous state and have preservative properties at the same time.}

@chaoticgood Just why are they only canned with cream at the moment?

_{For pressure purposes I guess} 

In over cases it is easier to remove air completely and create vacuum chamber

@chaoticgood anaerobic organisms will not be prevented from developing

@argentum I've never thought about it.. is there a great amount of anaerobic organisms?..

@chaoticgood well, if you mean in terms of numbers, or the number of species, then less than aerobic ones, of course, basically their natural habitat is the soil
