Process for preparing water extract of cinnamon
First Claim
1. A process for preparing cinnamon water extract, comprising the steps in the order of:
- (a) adding an aqueous solvent to at least 10 Kg of a cinnamon raw material, wherein the ratio of the solvent to the material is 1;
1 to 100;
1 (w/w),(b) boiling the mixture of (a) for at least 5 minutes,(c) removing the solid debris from the mixture to obtain a liquid portion,(d) concentrating the liquid portion by 5-50 fold,(e) storing the concentrated liquid portion at about −
5°
C. to 25°
C. until a top oil layer is formed and partitioned,(f) removing the top oil layer, and(g) collecting the remaining liquid portion.

Abstract
This invention relates to an improved process for preparing water extract of cinnamon in a large scale. The process comprises the steps of: (a) adding an aqueous solvent such as water to at least 5 kg of a cinnamon raw material at a water to material ratio of 1:1 to 100:1, (b) boiling the mixture of (a) for at least 5 minutes, (c) removing the solid debris from the mixture, (d) storing the liquid portion of the mixture at about −5 to 25° C., preferably 0-10° C., until a top layer of oil is formed and partitioned, (e) removing the top layer of oil, and (f) collecting the remaining liquid portion. The present process prepares a cinnamon water extract product with a minimal content of potentially toxic cinnamaldehyde and coumarin, while increasing the contents of the active ingredients of polyphenolic polymers for controlling blood glucose level.
