300CC(30-Pack) Food Grade Oxygen Absorbers Packets for Home Made Jerky and Long Term Food Storage

One of the seller comments says there is an indicator on the packet, so when I used them I left one packet out as a test (the rest went with dry food in mason jars).When I couldn't see any change in the test packet's markings the next day, I doubted the quality - but when I checked my mason jars the little dome on the lid had been pulled down, indicating a vacuum in the container. I'm assuming enough O2 gas was adsorbed to reduce the pressure in the jars.

Items seem to be work perfectly I used them to break down foodstuffs (Rice) from a 25 lb bag down to 2 lb (1Qt) bags. and they appear to perform as advertised. will probably buy more.

These are exactly what I needed for food storage. Even though I didn't use the entire package at one time, I store the extras in a mason jar with the indicator pkg facing out. I've these for over 3 weeks and they are still working according to that indicator.

Not one of these worked! Asked for a refund or replaced. No answer. Ordered from someone else. I am not new to using so that was not the problem.

my first time i work with this i like this idea the storege food for a emergency...... recived in time a good condition ...qty was perfect

I measured the oxygen level in a sealed 100 cc mason jar. It got down to 5% in about 30 minutes.

Fantastic for shipping vac packed foods like jerky

came ready to go! well packaged and fresh i will buy them again
