Abstract
Abstract A method for producing a moisture-stable product is elucidated, said process includes: admixing a low molecular weight water-soluble material (e.g., monosaccharides or disaccharides) having a molecular weight of from 90 to 500 molecular weight and a melting point of from 80° C. to 180° C., with a high molecular weight water-soluble polymeric material (e.g., polysaccharides) having a molecular weight of from 1,000-6,000. in an aqueous solution, adding a volatile flavorant (e.g., acetaldehyde) to said solution, and spray drying said solution within a temperature range of from 100° C. to 180° C. as an inlet temperature of 50° C. to 80° C. as an outlet temperature range.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
A process for producing a moisture-stable, fixed acetaldehyde composition having an amorphous substrate comprising the steps of: (a) forming an aqueous solution which consists of on a solids basis from 10 to 30% by weight of a water-soluble, crystalline, low molecular weight material which has a molecular weight of from 90 to 500 and a melting point of from 80° to 180° C. and no less than 70% by weight of a water-soluble, malto-dextrin having a D.E. of from 4 to 20 and an average molecular weight of from 1,000 to 6,000; (b) incorporating acetaldehyde into the solution of step (a) and thereafter; (c) spray-drying the aqueous solution.
Claim 2
Dependent Claim
108 words
A process for producing a moisture-stable, fixed acetaldehyde composition having an amorphous substrate comprising the steps of: (a) forming an aqueous solution which consists of on a solids basis from 10 to 30% by weight of a water-soluble, crystalline, low molecular weight material which has a molecular weight of from 90 to 500 and a melting point of from 80° to 180° C. and no less than 70% by weight of a water-soluble, malto-dextrin having a D.E. of from 4 to 20 and an average molecular weight of from 1,000 to 6,000; (b) incorporating acetaldehyde into the solution of step (a) and thereafter; (c) spray-drying the aqueous solution.
Claim 3
Dependent Claim
30 words
A process according to claim 1 wherein the low molecular weight material is selected from the group consisting of malic acid, citric acid, adipic acid, monosaccharides, disaccharides and combinations thereof.
Claim 4
Dependent Claim
81 words
A spray-dried, moisture-stable fixed acetaldehyde composition comprising: (a) an amorphous substrate consisting of from 10% to 30% of a water-soluble, crystalline, low molecular weight material which has molecular weight of from 90 to 500 and a melting point of from 80° to 180° C. and no less than 70% by weight of a water-soluble malto-dextrin having a D.E. of from 4 to 20 and an average molecular weight of from 1,000 to 6,000; and (b) acetaldehyde fixed within the amorphous substrate.
Claim 5
Dependent Claim
81 words
A spray-dried, moisture-stable fixed acetaldehyde composition comprising: (a) an amorphous substrate consisting of from 10% to 30% of a water-soluble, crystalline, low molecular weight material which has molecular weight of from 90 to 500 and a melting point of from 80° to 180° C. and no less than 70% by weight of a water-soluble malto-dextrin having a D.E. of from 4 to 20 and an average molecular weight of from 1,000 to 6,000; and (b) acetaldehyde fixed within the amorphous substrate.
