Pig intestines are typically soaked, washed, and boiled with salt or baking soda to remove any unpleasant odors. They naturally have a dark brown color, and fresh pig intestines should be odorless. The most commonly sold type is boiled pig intestines, which weigh around 1.6 kg. However, fresh pig intestines that have not been boiled weigh about 2.1 kg, and if they have been boiled, they weigh around 1.9 kg.
