Alternate to vaccum seal

[jJjburton]

If one has a big bag of some type of powder, lets say cane sugar 5 lbs. If you put the raws in the small small baggies with a silicone pack and then you that engulfed, after all this with the sugar, wouldnt this act as a vaccum type enviornment? Kind since there is no room for air?

Does this make sense?

Are you asking if the silica packs will remove the oxygen from the air inside the bag?

The opening of a bag allows air to move in and out. Depending on how tight the opening is sealed the less air movement. I have powders that have been in ziplock bags with a desiccant for years and they have stayed potent as far as i can tell.

I think I understand what you’re suggesting. The problem with this approach is that there is still a great deal of space between the individual crystals of sugar. In geological and materials science, the term is “pore space,” if you want to google for some more information. Our concept of distances doesn’t work well with insanely small structures, which is what you’re dealing with on the scale of individual gas molecules.

You would still need to pull a vacuum to eliminate the air, in which case, it’s easier to suck out air from a plastic bag than from a plastic bag full of sugar.

Vacuum sealed?, or just taking out as much air by hand?
