Super cool project, but I think there's pretty valid nitpick here:
It should clearly state the container (when multiple are possible) as that's likely the origin of 99.9% of the microplastics, as well as temperature. Prime example: "Starbucks Matcha Latte". I bet there are orders of magnitude difference in microplastic content between getting a hot one in a plastic (coated, if not fully) takeaway cup vs an iced one in a mug.
In general, containers and the way they're used generally make the difference, but all the focus here is only on the food item.
