Harlow,
Have you tried sodium benzoate?
In case sodium benzoate didn't help, you are gonna give more details of your product so others can offer you better ways to deal with the problem.
Are your tomatoes fresh-cuts, canned, juiced, mashed, etc...
Are the heat treatments (if any) sufficient to eliminate yeast?
Have you tried MAP (Modified Atmosphere Packaging) for your tomatoes?

Hello Immortal!
Have you tried using a lower pH (making your product more acidic, with vinegar for example)?

Normally I would use a heat treatment to kill yeast.
Potassium sorbate can be used as an inhibitor if you want to use a chemical ingredient.

Did you solve the problem Immortal?
Saw this question today. Hope you already solved it.
If not, could you provide us with some more background details/parameters like your processing methode (washing, heating) and water activity, pH, saltinity, acidity.
As it is more important to know what the cause is of the problem than put chemicals in to your product.
Make a note that the useing of E211 and E202 is not allowed in all countries
