Abstract
This invention refers to a method for reducing the color of any intermediate of a process for obtaining sugar, and sugar and a process for the production of low color sugar. This invention also refers to the use of components and combinations thereof for reducing the color of sugar and/or any intermediate of a process for obtaining sugar.
Claims5
A method for reducing the color of sugar or any intermediate of a process for obtaining sugar, consisting of adding to the sugar or any intermediate in a process for obtaining sugar:
- Component 1:
- a member selected from the group consisting of a sulfoxylate, a salt of the form M+−O—S(═O)—CH(OH)R, and a monobasic organic acid of sulfur having the general formula RSO2H;
- wherein M+ can be a mono or multivalent cation, and wherein R═H, C1-C20 alkyl, branched C1-C20 alkyl, cyclic C5-C6 alkyl, aryl, benzyl, or heterocyclic C5-C6 rings, and wherein R can be substituted or unsubstituted;
- or mixtures thereof;
- and
- Component 2:
- at least one of a sulfite, a metabisulfite, a bisulfite, or sulfur dioxide, or a source thereof;
- and
- Component 3:
- at least one chelating agent;
- wherein Component 2 is added at a temperature between 65° C. and 150° C. and at a pH of greater than 3;
- and wherein Components 1, 2, and 3 are added at the input of an evaporator;
- whereby the color stability of the sugar or any intermediate of a process for obtaining sugar is increased.
A process for the production of low color sugar or any intermediate of a process for obtaining sugar, which comprises adding:
- Component 1:
- a member selected from the group consisting of a sulfoxylate, a salt of the form M+−O—S(═O)—CH(OH)R, and a monobasic organic acid of sulfur having the general formula RSO2H;
- wherein M+ can be a mono or multivalent cation, and wherein R═H, C1-C20 alkyl, branched C1-C20 alkyl, cyclic C5-C6 alkyl, aryl, benzyl, or heterocyclic C5-C6 rings, and wherein R can be substituted or unsubstituted;
- or mixtures thereof;
- Component 2:
- at least one of a sulfite, a metabisulfite, a bisulfite, or sulfur dioxide, or a source thereof;
- and
- Component 3:
- at least one chelating agent;
- adding Component 2 at a temperature between 65° C. and 150° C. and at a pH of greater than 3;
- and introducing Components 1, 2, and 3 into the process at the input of an evaporator;
- whereby the color stability of the sugar or any intermediate of a process for obtaining sugar is increased.
A method for reducing the color of sugar or any intermediate of a process for obtaining sugar, consisting of the addition of:
- Component 1:
- a member selected from the group consisting of one or more of a sulfoxylate, a salt of the form M+−O—S(═O)—CH(OH)R, and a monobasic organic acid of sulfur having the general formula RSO2H;
- wherein M+ can be a mono or multivalent cation, and wherein R═H, C1-C20 alkyl, branched C1-C20 alkyl, cyclic C5-C6 alkyl, aryl, benzyl, or heterocyclic C5-C6 rings, and wherein R can be substituted or unsubstituted;
- or mixtures thereof;
- Component 2:
- at least one of a sulfite, a metabisulfite, a bisulfite, or sulfur dioxide, or a source thereof;
- and
- Component 3:
- at least one chelating agent;
- wherein Component 3 is added at the input of an evaporator;
- whereby the color stability of the sugar or any intermediate of a process for obtaining sugar is increased.
