FIELD: food industry.
SUBSTANCE: smoking device contains a receiving container holding or capable to hold combustible products, mainly - tobacco. Connected to the receiving container is a filtering element having at least one fragile capsule containing a core and a coating. The capsule initial crushing strength is from 4.9 to 24.5 N. After smoking test the capsule preserves crushing strength from 4.9 to 24.5 N. Before destruction the size of its deformation is less than two thirds of its diametre. The coating contains at least one hydrocolloids represented by gellan gum, agar, alginates, carrageenans, pectins, gum arabic, Ghatti gum, pullulan, mannan gum or modified starch taken singly or in a mixture or in combination with gelatine. The quantity of hydrocolloid in the coating is 1.5 - 95 wt %, predominantly - 4 - 75 wt % and more preferably - 20 - 50 wt % of the coating total weight. The method of such a capsule production involves coextrusion of hydrophilous outer liquid phase and lipophilic inner liquid phase; solidification and/or condensation of the coating surface by way of the capsule maintenance under cold conditions; the capsule final rinsing with an organic solvent; the capsules drying and additionally covering the capsules with at least one moister protecting layer.
EFFECT: invention allows to produce a capsule preserving its ability for destruction even after a moisture impact.
