I used vegetables juice for the additional liquid ingredients in milk bread, and it didn't rise. I think there is something in vegetables juice that killed the fermentation of dough.
This is a study, a food experiment. I used radish, mustard green, ginger, onion, garlic, beans, tomato, squash, eggplant, winged beans, winter melon, bitter melon, mexican turnip, and sponge gourd juice. The first step that we did was, we mixed first the yeast, milk and the juice. After mixing all the ingredients the dough become sticky, and it didn't rise.
In our first trial, we have done it right by using the extract of vegetables. And in our 2nd trial, we used the process of juicing, we actually use a juicer to get all the juice. and after all, the juice had an effect in our dough.
