They are also used as food for domestic animals.
Potato starch is used in the food industry as, for example, thickeners and binders of soups and sauces, in the textile industry, as adhesives, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; Other research projects seek ways to use the starch as a base for biodegradable packaging. Potato skins, along with honey, are a folk remedy for burns in India. Burn centers in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: They are all "standard" research organisms.
