Sour green beans and beets?

[KranK]

Sup i made some jars with green beans and some with beets. The recipe said to put some sugar and salt into the water. Both got pasteurized but it tastes sour. It doesn't look spoiled but tastes like it has fermented (a bit different than sauerkraut and pickled cucumber). But as i said they've been pasteurized. Any clue? Is it because of sugar? Or the brine? Now i think it may be because it's like brine for fermenting things like cucumber but with salt. The brine i used previous time had some vinegar.

It could be the brine.
