I am going to start making my own beans and broth (enchilada sauce too.) I was worried about freezing it because of BPA. Turns out Ziplock Brand bags (and SaranWrap brand) are BPA, phthalate, and dioxin free.
Sterilite ice cube trays are also BPA and phthalate free
Rubbermaid ice cube trays are BPA free, but I do not know if they are phthalate free. I posted that question on their website.
I thought everyone would like to know.
