They are generally canned and then heated to kill any bacteria.

Fresh tomatos are probably irradiated. They are nearly always kept refridgerated to slow the growth of microbes.

Here are some links:

I'm not an expert so i'm making an educated guess!

well to preserve it for lesser time
in ur refridgerator ,can be by wrapping them in tissue wrapigs and then rewrap in paper wraping ,this willl minimize the dehydrating efect. well if u r talking about industrial level preservation than canning wiht some optimized salt gradient may serve as a better tool.but since the r juicy and r prone to get easily contaminated there r very less probablity of this technique too.

the house wives use it as sauce in their cuisines.wen tomatoes r cheap get more quantities and preserve it by making homemade sauce and store it in the refridgerator.

i dont think it helped? lemme know.

You need to dip fresh tomatos in boiling water for just a few seconds, then put them in cold water. This scalds the skins and makes them easy to peel. Then just fill quart jars to within 1/2 inch of top and press them until juice comes to top and refill a little if neccessary. Then add one tablespoon of canning salt, a teaspoon of sugar if you want, screw on new lid hand tight, place in a hot water bath canner and boil for 20- 25 minutes.
