I've just started fermenting my own milk kefir. I found some how-to videos on youtube and sure enough, now I have a little microbial zoo growing on my kitchen counter. How cool is that? My kids are getting probiotic smoothies for breakfast. But today, looking for an explanatory link to send a friend who didn't know what kefir was, I came across this on Wikipedia:
"If the container is not light proof it should be stored in the dark to prevent degradation of vitamins and inhibition of the culture."
Degradation of the vitamins? None of the videos said anything about keeping it in the dark. Anyone heard of this? My kefir cultures just fine in a 24-30 hour period, out on the counter. I even stuck it in the sun today to speed things up a bit (successfully).
My gut reaction (ok, sorry for the pun) was that I'm doing the kefir for the probiotics and not the vitamins, so it doesn't matter. What do you think? Does light degrade vitamins in milk?
