Embodiment 1

[0512] Preparation of Reb DEMNO composition from commercially available stevia extract

[0513]Polymeric resins are used in the preparation of Reb DEMNO compositions. The resin is a copolymer of N-vinylpyrrolidone (NVP) and ethylene glycol dimethacrylate (EGDMA) with an average particle size (volume weighted average) of 60 microns. N-vinylpyrrolidone (NVP) in a 50:50 mass ratio of NVP:EGDMA was stirred at 75°C using lauroyl peroxide as the polymerization initiator and in the presence of cyclohexanol and 1-dodecanol. The resin is prepared by polymerizing an aqueous suspension of ethylene glycol dimethacrylate (EGDMA). The feed material used was a commercially available stevia extract "SGD" containing (wt / wt, dry basis) 23.78% Reb D, 2.58% Reb E, 11.31% Reb M, 6.88% Reb N, 5.53% Reb O, 9.29% Reb A, 3.25% steviol glycoside, 0.28% Reb F, 1.75% Reb C, 0.11% dulcoside A, 0.77% rubusoside, 0.36% Reb B, 0.07% steviolbioside. The polymer resin (2 g, free flowing) was mixed with etha...

[0517] Beverage preparation

[0518] Cola-flavored carbonated beverages:

[0519] Carbonated cola beverage samples were prepared using Reb DEMNO prepared according to Example 1 as the sole sweetener. Regular and diet cola beverages were prepared using the ingredients listed in Table 2. Diet beverages were sweetened with different stevia extracts containing a Reb DEMNO / T13SG ratio of 99.7% or a Reb A / T13SG ratio of 98%, respectively. The stevia composition was used at a concentration of 500 ppm.

[0520] Table 2.

[0521]

[0522] A 5-member training panel evaluated samples in duplicate for seven characteristics—sweetness, bitterness, sweetness linger, bitterness linger, astringency, brown spice, and vanilla notes. Diet beverages containing Reb DEMNO exhibited significantly higher sweetness and a more targeted flavor odor compared to the control beverage containing HFCS and the diet beverage containing Reb A. There was no difference in vanilla note and adverse character...

Abstract

Methods of preparing steviol glycosides, including Rebaudioside D, Rebaudioside E, Rebaudioside M, Rebaudioside N and Rebaudioside O are provided herein. Sweetener and sweetened consumables containingRebaudioside D, Rebaudioside E, Rebaudioside M, Rebaudioside N and Rebaudioside O are also provided herein.

Description

[0001] field of invention [0002] The present invention generally relates to the preparation of one or more steviol glycosides such as Rebaudioside D (Reb D), Rebaudioside E (Reb E), Rebaudioside Methods for M (Reb M), Rebaudioside N (Reb N), and Rebaudioside O (Reb O). The present invention also relates to sweetener compositions and sweetened consumables containing one or more steviol glycosides, including Reb D, Reb E, Reb M, Reb N, and Reb O, and methods for their preparation. The present invention also relates to methods of using Reb D, Reb E, Reb M, Reb N, and Reb O to provide sugar-like flavor and temporal profiles to sweetener compositions and sweetened consumables. [0003] Background of the invention [0004] Natural caloric sugars such as sucrose, fructose and glucose are used to impart a pleasant taste to beverages, foods, pharmaceuticals and oral hygiene / cosmetic products. In particular, sucrose imparts a preferred taste to consumers. Although sucrose provides a...
