Abstract: A method for forming encapsulated nicotine granules (ENGs) includes heating a first mixture to form a molten mixture, the first mixture includes one or more polyols; cooling the molten mixture to a first temperature to form a cooled molten mixture; adding at least one of nicotine and one or more nicotine salts to the cooled molten mixture to form a second mixture; cooling the second mixture to a second temperature to form one or more solidified structures, where the second temperature is different from the first temperature; and fragmenting the one or more solidified structures so as to form a plurality of encapsulated nicotine granules. The first temperature may be between about 120° C. and about 200° C. The second temperature may be below a glass transition temperature (Tg) of the one or more polyols. For example, the second temperature may be between about 65° C. and about 200° C.

Abstract: A method for preparing the nicotine-containing powder includes dissolving a carrier in a solvent to form a first solution, where the carrier includes a biopolymer, a natural polymer, a synthetic polymer, a bulk sweetener, or any combination thereof; contacting the first solution with nicotine, a nicotine complex, a nicotine salt, or any combination thereof to form a second mixture; and spray drying the second mixture to form a plurality of particles that define the nicotine-containing powder. The method may further include adding at least one of a pH modifier and an antioxidant to the second mixture. When the solvent includes water, an inlet temperature ranges from 120° C. to 210° C. and an initial product temperature ranges from 25° C. to 100° C. When the solvent includes ethanol, the inlet temperature ranges from 65° C. to 180° C. and an initial product temperature ranges from 25° C. to 79° C.
