1. A process for incorporating a volatile component into a matrix, comprising:
- (1) heating and mixing a matrix and a volatile component to obtain a liquid melt comprising said volatile component and said matrix; and
(2) solidifying said melt under a pressure sufficient to prevent substantial volatilization of said volatile component, wherein said solidifying is carried out in a pressure vessel under a pressure which is greater than the vapor pressure of said volatile component at the temperature of said melt, to obtain a dense, amorphous solid directly upon said solidifying said melt, wherein said volatile component is selected from the group consisting of diacetyl and acetaldehyde.

10. A process of encapsulating materials dissolved in a volatile solvent in a matrix, comprising:
-
(a) heating and mixing a matrix and a solution of a material dissolved in a volatile solvent to obtain a liquid melt comprising said matrix and said material dissolved in a volatile solvent; (b) adjusting at least one of the temperature and pressure of said melt to cause at least a portion of said volatile solvent to volatize to form a melt having a reduced solvent content; and (c) solidifying the resulting melt, wherein after said at a portion of said volatile solvent is removed, a volatile component is introduced into the resulting melt under pressure sufficient to prevent substantial volatilization of said volatile component to obtain a melt containing a volatile component, and said melt containing a volatile component is subsequently solidified under a pressure which is greater than the vapor pressure of said volatile component at the temperature of said melt, wherein said volatile component is selected from the group consisting of diacetyl and acetaldehyde. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
