None at all, due to our high-quality packaging. We use Tetra Pak packaging that is aseptic, sustainable, and environmentally friendly.
The main building materials of a Tetra Pak package are a paper carton (wood source), a very thin aluminum foil (that protects the product from oxygen and light), and a thin heat-resistant polymer (from sugarcane). This thin layer of polymer protects your bone broth from heat. Also, the broth inside the carton is protected from all outside contaminants due to it being vacuum sealed in the carton, in an aseptic environment. It’s how we have managed to ensure a two-year shelf life without adding any preservatives. You can rest assured that your delicious broth will be received as fresh and as safe as the day it was packaged.
