Abstract
Abstract A method for treating a sugar solution in which one, two or more than two kinds of esters selected from the group consisting of glycerol mono-aceto mono-fatty acid ester, glycerol mono-aceto di-fatty acid ester and glycerol di-aceto mono-fatty acid ester composed of a fatty acid of 12 carbons or composed of mixed fatty acids consisting at least 40% of a fatty acid of 12 carbons and the rest being fatty acids of 8 to 14 carbons are added to the sugar solution during a process of manufacturing sugars.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A method for treating a sugar solution, comprising adding an ester composition to the sugar solution during a process of manufacturing sugars, in an amount which is sufficient to defoam the sugar solution and reduce its viscosity and which is at least 0.001% of the sugar solution, wherein the ester composition comprises one, two or more than two kinds of esters selected from the group consisting of glycerol mono-aceto mono-fatty acid ester, glycerol mono-aceto di-fatty acid ester and glycerol di-aceto mono-fatty acid ester, where the esters of the ester composition have a fatty acid of 12 carbons or have mixed fatty acids consisting of at least 40% of a fatty acid of 12 carbons, the rest being fatty acids of 8 to 14 carbons.
Claim 2
Independent Claim
124 words
A method for treating a sugar solution, comprising adding an ester composition to the sugar solution during a process of manufacturing sugars, in an amount which is sufficient to defoam the sugar solution and reduce its viscosity and which is at least 0.001% of the sugar solution, wherein the ester composition comprises one, two or more than two kinds of esters selected from the group consisting of glycerol mono-aceto mono-fatty acid ester, glycerol mono-aceto di-fatty acid ester and glycerol di-aceto mono-fatty acid ester, where the esters of the ester composition have a fatty acid of 12 carbons or have mixed fatty acids consisting of at least 40% of a fatty acid of 12 carbons, the rest being fatty acids of 8 to 14 carbons.
Claim 3
Dependent Claim
31 words
The method for treating a sugar solution according to claim 1 wherein the sugar solution is selected from a solution of one or more kinds of sucrose, dextrose, fructose and maltose.
Claim 4
Dependent Claim
58 words
The method for treating a sugar solution according to claim 1 wherein the fatty acid of glycerol mono-aceto mono-fatty acid ester, glycerol mono-aceto di-fatty acid ester and glycerol di-aceto mono-fatty acid ester is consisting of crude lauric acid, purified lauric acid and fatty acids of coconut oil, palm kernel oil, hardened coconut oil and hardened palm kernel oil.
Claim 5
Dependent Claim
44 words
The method for treating a sugar solution according to claim 1 or claim 3 wherein the added quantity of glycerol mono-aceto mono-fatty acid ester, glycerol mono-aceto di-fatty acid ester and glycerol di-aceto mono-fatty acid ester is between 0.001 and 0.1% of the sugar solution.
