Of course this is the sort of thing that you do if you are really cheap, but I did it because I found the vacuum sealing stuff on an online auction site and it did not seem as though any other people were interested in it. I was curious about how you go about stuff like food packaging leak detection, which is the technical term for this stuff and the quality control systems that you use. However when you are going about it one operation at a time that is really simple. If it was a massive packaging operation where you had thirty tons of stuff get cleaned up and put in packages every hour, then you are going to have to worry about one or two little problems slipping past you. If you are doing it all on your own, one little thing at at time. Then it is not hard to make sure that you get it right.
At any rate this is mostly about the garden fresh stuff. I have about an acre and a half under cultivation with a lot of raised vegetable beds and some little greenhouses that I use year round. Some of it I sell to a friend of mine who is a chef, but he only wants the very best of the very best. So he will pick through it and nine out of ten pieces will not pass inspection. That is okay with me. I give away a lot of the food to other people, but I want to try to keep some fresh or nearly fresh food around all year round. Mostly this is going to be an experiment to see how well it works and if there is a limit to how much you can try to save without pickling and such.
