From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.

Potassium sorbate, also known as sorbistat-k, E-202 and sorbistat-potasium, is a white, odorless, and tasteless salt. Although it is naturally occurring in some fruits like berries, it is commercially produced by a neutralization reaction between sorbic acid and potassium hydroxide. It is an inactive salt form of sorbic acid and just like sorbic acid, it has been found to be active against molds, yeasts, bacteria and fungi. Because of these antimicrobial activities, it is often used as a preservative in the food and beverage industries to preserve foods like cheese, yogurt, dried meat, bread, cake, milkshakes, pickles, ice cream and apple cider.
