We combined the peels with 225 mL of water in a blender, which gave us an orange pulpy liquid.

When we reached 7 ml, we noticed our temperature rose to 98˚C and it stayed at a constant 98-99˚C throughout the rest of the experiment. After collecting about 35 ml of fluid, we noticed about 5 ml of organic phase that sat on
