New Snack and Pharmaceutical Processing Facilities

I think new recipes should be added to better reflect reality and demand.
Water + sugar + carbon dioxide = cola
Sugar + water + fruit/wheat = Alcohol
Currently, vitamins can only be obtained from vegetables and fruit.
Modern problems require modern solutions—add a new item: vitamins!
However, I'm not sure whether it would be better to produce them from petroleum or from plants; the recipe might need some consideration.

Cola as a "treats" category item would be fun, you could also have it consume aluminum, glass or plastic as packaging that would end up in the recycling.
Coffee or tea could be a good one, especially if it's one of those goods like the nebulous imported goods that you need to establish a trade contract to get.
A third vitamin category food that's a synthetic or cultured could be a fermentation recipe. Nutritional yeast is a popular food flavoring and source of some micronutrients for vegetarians and it's basically cultured the same way as penicillin, so it could come out of the fermentation tank.
