Bigdaddy, the juices can weaken the juices because of the heat its receiving from direct sunlight, not the light itself. Think of the old trick using a magnifying glass and piece of paper with the sun

I also have a candle/bath & body business. My fragrance oils, oil ingredients and flavor oils are affected the same way. I keep them in a storage closet where its and in a dark cabinet to prolong their shelf life.
