There aren’t many BPA-free food processors to choose from, simply because manufacturers love to use polycarbonate plastic for the bowl. As you know, polycarbonate plastic contains BPA.
Does it matter? Well, there is a great deal of movement that goes on in the bowl of a food processor, meaning the food is rubbing up against the plastic over and over again. If the food is already hot, then the chances of BPA leaching out from the plastic are increased.
Fortunately, there are a few choices available from companies which use different plastics for their bowls.
Plus there are some traditional alternatives, like manual food mills and, for some food preparation, you can still use a knife and cutting board instead of a food processor.
Hamilton Beach Big Mouth Food Processors.
I don’t know whether Hamilton Beach had the “BPA-free market” in mind when designing this line of food processors, but all their Bigmouth models are free of BPA. The bowls and lids are made of SAN (acrilonitrile/styrene copolymer), and the blade attachments are made of POM (Polyoxymethylene).
Vitamix makes high-end blenders, and while the prices they charge are pretty steep, a lot of people swear by them. Their 5200 series comes with a Tritan Copolyester 32-Ounce bowl and is BPA-free. This isn’t the case for their other models, but you can buy Tritan Copolyester bowls separately and use them to replace the original polycarbonate bowls which came with the blender.
This is your mother’s food processor. In fact, I remember my mother using one to puree fruits. They can also be used to shred vegetables, and to puree tomatoes and de-seed them. While not a complete alternative to automatic processors, they can be used in a variety of ways and are totally green: no plastic and no electrical power required.
