Onions are an important component to so many recipes and possible meals. They also contain a surprising amount of vitamins and minerals (see the extended nutrition guide in the photo gallery). Our new dehydrated onion bulk package contains over 30 CUPS of flavor for your meals. It is packaged in a one-gallon zip top (limited availability) mylar package that has been sealed for long term. We rate this item at 30 years due to it's minimal fat content, quality packaging materials and state of the art packaging method. As with all of our products, Mountain Fresh Foods uses a combination of vacuum sealing, nitrogen flushing AND oxygen absorbers - a combination of THREE methods where most companies use one of the three.
