storing hops etc

food - 26-9-2010 at 11:13

Hi
I have a question; it's not strictly hops-specific, but I am currently harvesting a modest amount of hops that I will freeze after I feel that they're dry enough. I did this last year and the hops that I used from the freezer seemed fine to me.

Oxidation of some of the hops components is to be avoided; it will impact the flavour in a negative way. As an extra precaution would anyone have any suggestions for something that would help in this respect. I see food with packets of 'anti-oxidant'. If I could add a 'tea bag' of something like that; something otc?

thanks

If only there was some kind of vessel full of microbes that could ferment the hops and keep is for you. . . . .

Though seriously, freezing sounds like a good idea.

Just store them in a plastic bag in the freezer with as little oxygen as possible. I don't know what "anti-oxidant" packets you are referring to. The only packets I have seen with food are packets of silica gel meant to absorb moisture not oxygen.

I have also seen little packets meant to absorb oxygen. I believe they contained sodium bisulfite or similar sulfite salt.

Freezing has worked well so far, and my freezer is way cold. It was an article on hop make up and chemistry that got me wondering. And I think that I've wondered about this before in other contexts.

Around here I've been seeing small packets inside beef jerky packaging; not as large as dessicant packets that I see, and iirc they're labeled as anti-oxidant.

As for the 'vessel full of microbes that could ferment the hops' etc .. dude! that's me that your describing!

Some instant noodles come with O2 suckers.

instant noodles?

good to know, I'm going to keep an eye out for that

I'd eat instant noodles; it's a sacrifice that I'm willing to make

I keep mine in the freezer. Mine come in the aluminized mylar bags which keep the "freezer flavor" out. Fresh granulated activated carbon also adsorbs free O2.

Cheers,

Some of the anti-oxidant packets contain iron powder plus a bit of other stuff; they are decent sources of small amounts of iron 'filings'. You could use iron filings I suspect.

Use CO2 to flush the bags if you're really worried, either a small bit of dry ice or make your own from NaHCO3/whatever acid.

ok and ok

I just heard about those mylar bags and their odour-blocking properties. Hadn't realized that was one of their strengths. I just thought it was supposed to look glossy! "Anything that you may wonder about, industry has already solved it", I was told.

Hey. Store it in a relative vacuum. Then freeze it.

Special bags are available for such a procedure. Here in The States, on late night television.....they advertise a special device for removing air, from special vacuum storage bags.

You could improvise though. But, get the air out.

will check that

I'm gaining a new respect for packaging

"retort pouches", yow!

the name alone inspires respect

I checked out one of those oxygen absorber packets; damn if the thing didn't stick to a magnet! Iron filings! I was expecting something a bit more space-age. Mind you, I don't what else is in there
