I guess it depends on what you are sealing. I vac seal dry foods and put in an oxygen absorber and a moisture absorber. But some dry foods shouldn't have an oxygen absorber. Dry beans, peas etc are best vacuum sealed with both absorbers added. Grains naturally have bug eggs in it to start with. Absorbers kill the bugs.It it worth the cost and effort to Vacuum Seal Food?
How long of a shelf life could I expect from vacuum sealed food?
What vacuum sealers do you recommend?
What are your experiences with vacuum sealers and vacuum sealed food?
