Appeal No. 1996-3537
Application No. 08/302,596
Claim 1 is representative of the subject matter on appeal
and reads as follows:
Claim 1. A method for producing a microcapsule flavor
delivery system comprising:
(a) providing a mixture of a flavoring material selected
from the group consisting of an oil soluble flavor dissolved
in an oil and an o/w emulsion flavor and a protein solution;
(b) subjecting said mixture to low shear mixing to
provide an o/w pre-emulsion;
(c) subjecting said pre-emulsion to high shear mixing or
sonication to provide an o/w emulsion having a coating of
protein around the internal oil droplets;
(d) mixing the o/w emulsion with a liquified hard fat
which is solid at room temperature to provide an o/w/o
emulsion; and
(e) atomizing the o/w/o emulsion onto a planar surface or
into a fluid to provide microcapsules having a flavoring
material in the internal oil phase, said microcapsules having
a particle size of from about 20 microns to about 200 microns.
As evidence of obviousness, the examiner relies on the
following prior art:
