sasha.. and others on maf 878....when u made up the mixture and then refrigerated it.. did you put the finished product in a SEALED container? i didn't and i was gone from home for a few wks. when i got back a fluffly film had formed on the top of the bottle ...so am wondering if it is safet to use?
I don't put mine in a sealed container, just a glass jar with a glass lid resting on the top. Actually, two glass jars so one goes untouched for a couple of weeks and it doesn't grow a fluffy layer.
When I'm culturing the MAF, it grows a sort of crust a couple of inches thick each day for the five days that it stands out on the kitchen counter and I have to break up the layer with a spoon. I wonder if that's like your fluffy layer. Did you just mix the ingredients and put your MAF straight in the fridge, or did you do the five-day process of culturing at room temperature first?
I don't know the answer to your question, I guess is the short answer! I sniff the MAF occasionally to check if it smells other than yoghurty or cheesy. If it ever smelt mouldy, I'd be worried.
Do you get yours from Dr Enlander? If so, you could contact his office and ask.
