Distillate at home storage, preventing oxidation? Using water in the headspace of jars?

Water carries dissolved oxygen. And your oil is not pure so terpenes polyphenols lipids etc react. Try it and youll find out.

doing soā€¦

Can we use helium to back-fill vs argon or l2? I have a helium tank I used to find spd leaks (itā€™s really not needed).

44

How long does this work?

Seems like it would slow down oxidation, not stop it.

There is dissolved oxygen in water. I have a DO meter.

Hot water holds less dissolved oxygen. At 100C it canā€™t really hold any. I wonder if you could use steam to fill the headspaceā€¦would that be enough water after it condenses?

Iā€™m pretty sure helium will leak out of a mason jar. Plus youā€™d have to fill it upside down since itā€™s less dense than air. Other storage vessels though, maybeā€¦

Mason jars really donā€™t seal all that well unless under vacuum, which is what theyā€™re designed for. I remember trying to carbonate beer in them back in the day and it ended up being a terrible idea. Hell, theyā€™re really not even any good to store carbonated beverages in. In college we tried to save all the beer from a keg party by pouring into mason jars. The beer went totally flat within 48 hours.

Edit: On second thought, maybe you could keep the helium in it by storing the jar upside down? :thinking:

yes i dont think it stops oxidation but i do think it slows it down significantly

well for guac ive kept an open container of the shit in the fridge for 2 weeks without it turning brown. keeping open guac past 2 weeks in the fridge is pushing it lol.

Four common techniques for the removal of dissolved oxygen from water have been examined: boiling at 1 atm, boiling under reduced pressure, purging with N(2) and sonication under reduced pressure. After treatment, the residual oxygen in solution was analysed by the Winkler method. Nitrogen purging for 20-40 min at flow rate of 25 mL/s was found to be the most effective oxygen removal method. Boiling at 1 atm was found to be the least effective. None of the techniques evaluated here lead to complete removal of oxygen. The concentration of residual dissolved oxygen after purging for 20-40 minutes with nitrogen is 0.2-0.4 ppm.

Nice! Thanks for sharing that bit about wine saver argon

Iā€™m testing 2 jars stored in the fridge right now. 1 has a few mm of distilled water on top. Another one has the headspace filled with an argon, co2, n2 mix used in wine storage. The first experiment yielded a sop and I witnessed no darkening over a weeks time. I would dump the water out after pulling from the fridge. After shaking and getting as much water out as I can I used a new cheap hair dryer set to cold no heat and wedged it in the top to quick dry the top layer. Took about 5 mins and the water was fully evaporated off the top of the hard distillate.

I started using the Food Saver w/Mason jar adapter. Sealing takes like 10 seconds, if that

I can only get larger jars to vacuum seal with the food saver thing.

I canā€™t get 4oz jars with regular mouth to hold a vacuumā€¦I even bought a second regular mouth adapter.

No problem vacuum sealing wide mouth jars.

Great Idea!

Youā€™re going to want something heavier than (or at least closer to) air. Unless you are going to introduce the helium and cap with the bottle upside-down.

I canā€™t take the credit, I read it elsewhere on the forums

If you put your jars in your vac oven with the lid plate on And the ring unscrewed. You can vacuum down the oven and now all the jars in there are vacuum sealed at once with a much deeper vacuum

It doesnā€™t suck the lid down as soon astou tuen on the vac? Im really just wondering never tried it that was just my first thought. Has it been working for you?

56

I was always told to put your lids loosely on your mason jars in a vac oven, pull vac and when you let the vacuum out of the oven the lid will seal. Open the door and tighten the lid on and its mostly air tight.

Iā€™ve found light to be the biggest factor for oxidation.

Theres a big difference between keeping your disty in a refrigerator or a safe vs having it out where light can get to it

Ill give it a shot when i get to the shop, all mines kept in a safe so no light. As always thanks for the tip mich appreciated

I was going to try these but didnt. They work well?

I was still getting darkening over the course of weeks with vacuum saver kits or using my vac.chamber. both were basically unsuccessful for long term storage

Distillate is sold before I even make it. I mostly just seal them for a week or so until I begin filling orders.
