Abstract
A process for producing a dried product, optionally in the form of a flake, the process comprising (a) combining an active ingredient with a carrier, and an optional stabilizer, to create a wet mixture, wherein the active ingredient and carrier are in a ratio of about 1:1 to about 1:250 in the wet mixture; (b) spreading the wet mixture on a belt of a thin film belt dryer with a belt temperature in the range of about 60° C.-92° C.; and (c) drying the mixture to produce a dried product with less than about 7% moisture, optionally about 2-5% moisture, and a water activity of about 0.15 and about 0.65; as well as a dried product that can be produced by the method, and related methods and compositions.

A dried product, optionally in the form of a flake, comprising an active ingredient, a carrier and an optional stabilizer, wherein the flake has one, more than one, or all of the following properties:
- (a) the flake has a glass transition of about 58.7-62.6 at a water activity of about 0.1 to 0.6 optionally about 0.23-0.239 by differential scanning calorimetry;
- (b) the dried product has a glass transition temperature of about 40.5-80.0° C., optionally about 51.7-68.8° C., when measured at a water activity of about 0.23 to about 0.2;
- (c) the dried product appears shiny, glossy, sparkling or shimmering when compared to a comparable spray-dried composition, as determined by a human sensory panel;
- and an average gloss measurement of greater than about 1.9 at a 60-degree angle;
- (d) the active ingredient is dispersed in globules embedded in the carrier and the dried product comprises at least about 0.01 wt. % of the active ingredient;
- (e) the active ingredient is dispersed in globules embedded in the carrier, the globules being predominantly less than about 500 microns in diameter;
- (f) the dried product absorbs less than about 10% water by mass when exposed to a vapor of excess magnesium chloride solution (32% relative humidity) in an air-tight container for 1 week;
- and/or less than about 30% water by mass when exposed to a vapor of saturated sodium sulfate solution (81% relative humidity) in an air-tight container for 1 week;
- (g) the dried product is a flake with a thickness of about 10-1000 microns;
- and
- (h) the dried product is a flake circumscribed by a circle of between about 6 mm and about 20 mm.
A dried product comprising a carrier, an active ingredient comprising a terpene or botanical extract, wherein the dried product is in the form of a flake and has less than about 7% moisture, optionally about 2-5% moisture, and a water activity of about 0.15 and about 0.65.
A process for drying a colored material comprising macerating a starting material in an ethanol-water mixture, optionally about 6% to 35% ethanol, and conductance window drying the macerated material, optionally wherein the starting material is a plant material.
