I received the following question in response to my yesterday's post: You wrote that 5 PP plastic is safe, but actually substances extracted with polypropylene are toxic because it leaches in them. This is a great question and I am glad I got it so that we can unveil a big moment of truth here.
Plastic number 5 which is polypropylene also written as PP is safe to use as a plastic container made out of it. This doesn't mean that it is safe to use polypropylene to extract substances from foods. This is a completely different practice and I wish to make a point ouf the fact that extracting substances from foods with any synthetics, be it PP or others, produces toxic results. Be aware of this truth and use it to be safe and healthy.
