The main part of a shell of a pine nut (91,73) is made by carbohydrates, mainly cellulose (69,06%). Availability of mineral substances (0,92%) and high content of carbohydrates characterizes a shell of a pine nut as a source of a carbohydrate and mineral complex and various organic substances. The chemical composition of a shell of a pine nut is made: cellulose - 69%, cellulose - 38,6%, lignins - 23,8%, a gemitsellyuloza - 7,7%, pentozana - 22,67%, fats and pitches - to 3,4%, a squirrel - to 1,8%, ashes - to 0,9%, vitamin. From 27 mg of %, resinous substances, water-soluble - to 3,6%, contain insignificant substances of essential oil. The shell has peculiar amino-acid and macro - microelement structure, excellent a little increased content of glutaminovy acid.
It should be noted that the structure macro - and minerals of a shell and a kernel of a pine nut differs by quantity of the contained elements. In a shell iodine, pine forest, cobalt, strontium - indispensable elements of a kernel are not found. In too time the shell contains tin, the titan, vanadium and barium.
Also as a part of a shell of a pine nut dyes and tannins or tannida contain. Tannida of seeds of a shell of a pine nut treat pirokatekhinovy type. Tannida are capable to enter superficial interaction with very large number of substances. They can be adsorbed by many substances (coal, graphite, cellulose, etc.) and to adsorb on the surface, truly dissolved substances, in particular sugar, phenols, anions of monobasic fatty acids (acetic and its homologs), sulfonic acids, etc. The tannins or tannida which are contained in a shell of pine nuts are capable to change a colloidal state of proteins, have the knitting, antimicrobic, anti-inflammatory effect, promote tightening of skin, form a protective film under which the new layer of young cages is restored on mucous membranes and wound surfaces.
