Building pressure chamber for fizzy fruit - PVC safety I'm building a pressure chamber with some basic brass plumbing parts and a cylinder of CO2. The goal here is to infuse fruit with CO2.
I'm aware of the various safety aspects to consider since the system is under pressure. I had intended to use PVC for the chamber along with PVC cement to bond the plastic pieces. The setup is that the fruit would be placed inside the chamber in a food safe bowl, and CO2 would be injected into the chamber at around 45-60 psi. For reference, a soda bottle at room temperature is ~60psi.
PVC has a smell to it, and I was wondering if there are any food safety issues in using PVC in this way?
I would advise against your approach, as you are potentially building something that could explode and seriously injure someone.  If you have an ISI (or other brand) whipper, you can do this safely.  Alternatively, you can use dry ice and a Styrofoam cooler for the same effect.
