Abstract

Abstract Volatile enhancer, such as acetaldehyde, is mixed with a high concentration aqueous sucrose solution. The mixture is cooled to effect crystallization of the sucrose in the presence of the enhancer. The crystalline slurry is partially dried to a pasty consistency of about 12 percent moisture content and blended with crystalline sucrose to further reduce its moisture content. The blended material is then dried to a stable moisture level.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 23 words
The method of claim 1 wherein the crystalline slurry is partially dried to a pasty consistency before being blended with the crystalline sucrose.
Claim 2
Dependent Claim 21 words
The method of claim 2 wherein the paste has a moisture level of from 10 percent to 15 percent by weight.
Claim 3
Dependent Claim 18 words
The method of claim 3 wherein the paste has a moisture level of about 12 percent by weight.
Claim 4
Dependent Claim 32 words
The method of claim 3 wherein sufficient crystalline sucrose is blended with the paste to reduce the percentage moisture level of the blend to from 4 percent to 8 percent by weight.
Claim 5
Dependent Claim 14 words
Th method according to claim 4 wherein the sucrose solution is agitated during crystallization.
Claim 6
Dependent Claim 25 words

Claim 7
Dependent Claim 16 words
The method according to claim 7 wherein a crystal yield of about 50 percent is obtained.
Claim 8
Dependent Claim 12 words
The method according to claim 7 wherein the volatile enhancer is acetaldehyde.
Claim 9
Dependent Claim 26 words
The method according to claim 2 wherein at least a part of the crystalline sucrose blended with the paste has volatile enhancers fixed with its crystals.
Claim 10
Dependent Claim 25 words
The method according to claim 1 wherein at least part of the sucrose blended with the crystalline slurry has volatile enhancers fixed within its crystals.
Claim 11
Dependent Claim 34 words

Claim 14
Independent Claim 147 words
A method for entrapping low levels of acetaldehyde within sucrose crystals comprising the steps of: a. forming concentrated sucrose solution containing about 70 percent to 85 percent sucrose by weight, b. adding acetaldehyde to the sucrose solution at a level of about 1.5 percent to 5 percent by weight, c. slowing cooling the solution by condensing escaping acetaldehyde and retaining the condensate to the solution, d. further cooling the solution to a temperature of about 60*F., e. maintaining said temperature for a sufficient period to achieve about a 50 percent crystal yield, f. vacuum drying the crystalline slurry to a moisture level of about 10 percent to 15 percent by weight, g. blending crystallIne sucrose with said partially dry slurry to reduce the moisture content of the blend to from 4 percent to 8 percent by weight, and h. drying the blend to a stable moisture level.
Claim 15

Claim 17
Dependent Claim 18 words
The method according to claim 15 wherein the crystalline slurry is vacuum dried to about 12 percent moisture.
Claim 18
Dependent Claim 24 words
The method according to claim 18 wherein sufficient crystalline sucrose is added to reduce the moisture content of the blend to about 6 percent.
Claim 19
Dependent Claim 19 words
The method according to claim 15 wherein at least part of the crystalline sucrose contains acetaldehyde within its crystals.
