AI Technical Summary

Problems solved by technology

It is noted that using heat for dissolution of Reb D may not be possible in compositions containing heat sensitive components.
Also maintaining high temperature of mixture for prolonged time to prevent premature crystallization of Reb D can cause thermal degradation of mixture components or undesirable changes of organoleptic properties.
Extended time period of said vacuum thermal treatment is a disadvantage as well.
It is noted that the said method describes only a solubilization technique for a specific aqueous liquid, and does not provide readily usable form of highly soluble Reb D.
It is noted that some techniques described within the application, such as freeze-drying, are difficult to implement in large-scale multi-ton productions.
The significant portion on non-sweet (low sweetness) compound, (i.e. cyclodextrin), reduces the overall sweetness of the mixture as well.

Preparation of Reb D Concentrated Solution

[0036]100 g of rebaudioside D produced by PureCircle Sdn Bhd (Malaysia), with 98.1% purity (dry weight basis), having water solubility of 0.03% at room temperature was mixed with 400 g of water and incubated in thermostatted oil bath. The temperature was increased at 1° C. per minute to 121° C. The mixture was maintained at 121° C. for 1 hour and then the temperature was decreased to 80° C., at 1° C. per minute to make Solution#1.

Preparation of Reb D and Reb A Concentrated Solution

[0037]70 g of rebaudioside D with 98.1% purity (dry weight basis), having water solubility of 0.03% and 30 g of rebaudioside A with 98.6% purity (dry weight basis), and having water solubility of 5.5%, both produced by PureCircle Sdn Bhd (Malaysia), were mixed with 400 g water and subjected to heat treatment as described in EXAMPLE 1 to make Solution#2.

example 3

Preparation of Reb D and Reb B Concentrated Solution

[0038]70 g of rebaudioside D with 98.1% purity (dry weight basis), having water solubility of 0.03% and 30 g of rebaudioside B with 99.0% purity (dry weight basis), and having water solubility of 0.01%, both produced by PureCircle Sdn Bhd (Malaysia), were mixed with 400g water and subjected to heat treatment as described in EXAMPLE 1 to make Solution#3.

Abstract

A method for making highly soluble Stevia sweetener compositions is described. The resulting sweetener compositions readily provide high concentration solutions, and also possess superior taste qualities. The compositions can be used as sweeteners, sweetness enhancers, and flavor enhancers in foods, beverages, cosmetics and pharmaceuticals.

Description

FIELD OF THE INVENTION[0001]The invention relates to a process for the preparation of highly soluble sweet glycosides from a Stevia rebaudiana Bertoni plant, and more particularly for preparation of highly soluble compositions containing rebaudioside D.DESCRIPTION OF THE RELATED ART[0002]The extract of Stevia rebaudiana plant (Stevia) contains a mixture of different sweet diterpene glycosides, which have a common aglycon—steviol and differ by the presence of carbohydrate residues at positions C13 and C19 of steviol molecule. These glycosides accumulate in Stevia leaves and compose approximately 10%-20% of the total dry weight. Typically, on a dry weight basis, the four major glycosides found in the leaves of Stevia are Dulcoside A (0.3%), Rebaudioside C (0.6-1.0%), Rebaudioside A (3.8%) and Stevioside (9.1%). Other glycosides identified in Stevia extract include Rebaudioside B, C, D, E, and F, Steviolbioside and Rubusoside. Steviol glycosides differ from each other by their taste pr...
