  • Saharas - represented by maltose, sucrose, glucose and phosphate esters. But the more of these components are contained in the fruit, the worse their quality. Too sugary specimens are sweet in taste and darken when cooked.
  • Cellulose - contains only 1%. It is more concentrated near the peel, less than its core.
  • Hemicellulose - the content is 1 percent, together with the fiber is the basis of cells.
  • Nitrogenous substances - represented by raw protein, make up about 3%. Their peculiarity lies in the fact that according to their biological value they are practically not inferior to meat, egg and cereal proteins. This fact is explained by the interacting essential amino acids.

  • Amino Acids - lysine, valine, isoleucine, tryptophan, methionine, leucine, phenylalanine, threonine.
  • Organic acids - lemon, apple, isolimon, oxalic, wine, dairy, quinine, pyruvic, chlorogenic.

  • Carotenoids - are coloring matter. In yellow fruit potatoes amount to 0.15%, and in white fruit - 0.02%.
  • Flavones, anthocyanins, flavonoids - are the main components of potato peel.
  • Coumarins.
  • Amides - represented by glutamine and asparagine.
  • Nitrogenous glycosides - chakonin and solanine. The impact of these components is noticeable by a certain bitterness appearing in the mouth when the peel is chewed. If you store potatoes under the light, the amount of glycoalkaloids in its composition increases, as a result of which the fruit becomes poisonous.
