Abstract: Disclosed herein is a cold smoke smoker for cold smoking foods using materials heated to a controlled temperature for use in food service, commercial, and residential environments. The cold smoke smoker comprises a blower fan which blows smoke up through a vent, past an ignition plate smoking the materials, and through tubing into a food package containing food. The materials that are smoked can include natural wood chips, herbs, spices, or blends of the fore mentioned materials.

Abstract: This invention relates to colloidal dispersions of an alkaline earth metal salt in an oil-soluble acrylic polymer which is polymerized from a monomer system of at least one alkyl or hetero-substituted alkyl ester of an acrylic monomer selected from the group consisting of methacrylates and acrylates represented by the formula: ##STR1## wherein R.sup.1 is a --CH.sub.3 or --H radical, and R.sup.2 is selected from the group consisting of C.sub.1-30 alkyl and hetero-substituted alkyl radicals. This invention also relates to colloidal dispersions as described hereinabove wherein the monomer system further includes at least one non-acrylic polymerizable ethylenically unsaturated nitrogen-containing compound. Preferred polymerizable ethylenically unsaturated nitrogen-containing compounds are those selected from the group consisting of 2- and 4-vinylpyridines and N-vinyl-2-pyrrolidinones.
