Default Sugar storage in mylar...remove air?



Advertise Here

Hello folks. I just received my first batch of mylar bags from one of the merchants listed on this board.

I know it's not recommended to add o2 absorbers to suger or salt, but I was wondering about removing air from the bag.

I loaded one 1 gallon mylar bag and manually removed most of the air, leaving just a little in order for the bag to be somewhat flexable.
I didn't like the "air pillow" effect after the bag was sealed, so I tried using my HVAC vacuum pump to remove air on the 2nd bag I loaded.

I liked the way the bag compressed. My question is this:
Will removing some of the air out via the vacuum create the clumping or hardening i have read about here, or does that only happen as a result of using the o2 absorbers?
I don't want to continue my packaging untill i have a better understanding of the results.I don't want to waste time and product.
thankyou

I just seal mine up. I try to push out as much air as possible but don't worry about a little left inside the bag. Same with salt too.

it may clump a little but sugar is sugar and at the end of the day it will still be sugar.

Doesn't matter at all. All you need to do is keep it dry and keep ants out of it. Removing air won't cause it to clump. I think what makes it clump when you use an O2 absorber is the moisture the absorber gives off as it works. It'll clump salt too.

I just got some mylar bags, too. I have been too scared to use them, though. Like you - I don't want to waste them.

I have beans and rice and flour for mine right now. Thanks for the tip on sugar and salt - I didnt know you can do them without the o2 absorbers.

All crystalline materials tend to clump into a solid mass over time regardless of whether they are exposed to O2 or not. That is because the individual component crystals (eg. sugar, salt or some other compound) fuse together as a natural process of crystal growth. I know this from experience of doing scanning electron microscopy on pharmaceutical compounds in a quality assurance job that I had years ago.

Sugar and salt will stay good practically forever without any special preparation. Just protect it from pests - put it in a sealed, hard container. You do not need to worry about microbeasties or bacteria degrading the food like other foods, no need to use O2 absorbers or mylar.

Save your $$ and just get some cheapo plastic jars that will keep the ants and such out.

Absolutely correct .... must use a FOOD GRADE container however .... salt/sugar will pick up the contaminates and odors just like any other foods ..... if you buy in 4lb packs, remove from paper bags before packing ..... lifetime storage

If the sugar is a 'rock' when you're ready to consume it, just use a cheese grater or microplane to return it to a useable state.

BTW-anyone notice sugar is stating to slowly go down in price. Now if peanut butter and chocolate could follow suit.

That's how I do it, too. Keeps it dry and bug-free.

Dammit newbies, stop resurrecting old threads when you don't have anything to add to them! If you have something to add other than "me too" then please feel free. Otherwise they just add to the clutter.

Maybe there should be a sort of "agreement" newbies sign when they join, such that they acknowledge the following:

1. Do not start new threads without searching for recent threads first; here's how.

2. Do not resurrect threads older than 2 years unless you have a very good reason for doing so.

3. "Me, too" posts are not informative; indicated agreement through "thanking" a poster.

4 Everyone here is trying to learn as well as pass on what they know. Do not engage in personal attacks, and work to ensure that what you post is correct.

Perhaps each statement would have a checkbox next to it such that a newbie could not join unless she/he acknowledged, through the checkbox, that they'd read it, and if they violate the agreement they get a 3-day timeout?

Easy for me to say, I don't have to moderate it. Just a thought.

**************

My sugar is stored, in the original bags, in 5-gallon food-grade buckets. I can get five 5-pound bags in one bucket. Don't know how many 4-pound bags I could get in one.

We've got a couple of newbies right now who must think there is an award for resurrecting old threads.
