Abstract
The invention relates to a seamless breakable capsule of the core-shell type, the shell comprising a hydrocolloid, the core comprising a flavoring and a lipophilic solvent, characterized in that said shell is coated with a film coating layer that gives it water resistance, said film coating layer comprising polyvinylidene chloride; an oral-use pouch containing said capsule, a consumable product containing said capsule, a tobacco heating device containing said consumable product, a method for manufacturing said capsule, the use of said capsule as an agent for immediate and sustained release of a flavoring, and a method for flavoring an oral-use pouch.
Claims24
Seamless breakable capsule of the core-shell type,
- the shell comprising a hydrocolloid,
- the core comprising a flavoring and a lipophilic solvent,
- characterized in that said shell is coated with a film coating layer which gives it water resistance, said film coating layer comprising polyvinylidene chloride.
Method for manufacturing a seamless breakable capsule comprising a shell and a core, comprising the steps of:
- (A) co-extrusion of a hydrophilic external liquid phase and a lipophilic internal liquid phase, the external liquid phase comprising from 4 to 95% by weight of a hydrocolloid relative to the total dry weight of the shell, the internal liquid phase comprising 5 to 70% by weight of flavoring agents relative to the total weight of the core;
- (B) solidification and/or gelation of the surface of the capsule obtained in step (A), by immersion in a fluid that is at a temperature of between 1° C. and 25° C.;
- (C) drying of the capsule obtained in step (B);
- (D) film coating of the capsule obtained in step (C) by an air spray coating process using a film coating solution comprising polyvinylidene chloride and water;
- (E) retrieval of the capsule obtained in step (D).
