There is an antenna right under the label on the front of a bottle of St. John's Wort. Manufactured by
Minneapolis, Mn 55447
The antenna is like a printed coil, laid flat, like a spiral of metal foil, only in this case in a square shape. Upsher-Smith has a web site. From the research I've done, this coil delays food from spoilage, up to three days on milk at room temperature. In three experiments this has proved to keep milk from souring three time longer than the same bottle with the antenna removed. I've have two of these bottles. I removed the printed coil from one. Then I put milk in both bottles. The one with the coil didn't sour.

I talked with Rob Lovenger at Upsher-Smith in the marketing department (800-328-3344). He was unaware of the antenna function on the bottle other than thinking it had to do with anti-theft in the store.

Why don't you try making your own mini-coils with very thin gauge wire, cementing them in place and perhaps lacquering over that. Even a single strand from #20 or 22 gage ought to work OK. The ends of each individual coil should not touch. The individual coils should be placed one inside the other, but none of them touching each other at any point. These coils will capture cosmic frequencies and harmonics that may or may not be the correct supporting frequencies of the foods that you are trying to prevent from spoiling. You'll have to experiment to see what size coils provide the greatest activity.
