The best way to prolong the freshness and life of any food (or product) by far is to vacuum seal them. 
Here I have fresh organic chili peppers grown in my mom’s kitchen garden. I just take a handful of chili peppers and put them in these clear bags.
I used a Kenmore machine (which does not use a snorkel) to seal them. Machines with a snorkel (which are usually meant for clear poly bags) don’t tend to pull a lot of vacuum and therefore many people don’t like them. I pulled 26″ of Mercury within 5 seconds on the Kenmore. Machines with a snorkel probably pull only about 14″ of Mercury, and will probably lead to a food freezer burn.
