PROBLEM TO BE SOLVED: To provide a sweetener composition which has a sugar-like temporal profile, including onset sweetness and lingering sweetness, and/or a more sugar-like flavor profile.SOLUTION: A functional sweetener composition comprises at least one antioxidant, rebaudioside A, and erythritol, and further comprises a sweet taste improving composition. The weight ratio of the rebaudioside A and erythritol is between 1:4 and 1:800.

High-potency sweetener composition with antioxidant and compositions sweetened therewith

The present invention relates generally to improving the taste of natural high-potency non-caloric or low-caloric sweeteners and compositions sweetened therewith. In particular, the present invention relates to compositions that can improve the tastes of natural high-potency non-caloric or low-caloric sweeteners by imparting a more sugar-like taste or characteristic. In particular, the compositions and methods provide a more sugar-like temporal profile, including sweetness onset and sweetness linger, and/or a more sugar-like flavor profile, including osmotic taste.

Natural high-potency sweetener compositions with improved temporal profile and/or flavor profile, methods for their formulation, and uses

Exemplary embodiments of this invention encompass a method for purifying crude rebaudioside A. In particular, this invention relates to a method for purifying crude rebaudioside A compositions comprising purities from approximately 40 % to approximately 95 % rebaudioside A to obtain a substantially pure rebaudioside A product with a single crystallization step. Resulting polymorph and amorphous forms of rebaudioside A and methods for preparing polymorph and amorphous forms of rebaudioside A from crude rebaudioside A compositions and substantially pure rebaudioside A compositions also are disclosed.

Rebaudioside a composition and method for purifying rebaudioside a

The present invention relates generally to tabletop sweetener compositions comprising non-caloric or low-caloric natural high-potency sweeteners and methods for making and using them. In particular, the present invention relates to different forms of tabletop sweetener compositions comprising at least one non-caloric or low-caloric natural high-potency sweeteners in combination with at least one bulking agent, or at least one sweet taste improving composition, or at least one anti-caking agent, or combinations thereof. The present invention also relates to tabletop compositions and methods that can improve the tastes of non-caloric or low-caloric natural high-potency sweeteners by imparting a more sugar-like taste or characteristic. In particular, the tabletop compositions and methods provide a more sugar-like temporal profile, including sweetness onset and sweetness linger, and/or a more sugar-like flavor profile.

High-potency sweetener composition with dietary fiber and compositions sweetened therewith

PURPOSE: To produce a stevia sweetener having improved flavor free from bitterness and aftertaste, by decomposing selectively sweetening components except rebaudioside A in stevia sweetening components with a fungus or an enzyme. CONSTITUTION: An aqueous solution containing rebaudioside A and stevia sweetening components except it or an extracted solution of leaves of Stevia rebaudiana BERTONI is treated with a fungus such as Aspergillus nigar ATCC-6275, etc., capable of decomposing selectively the stevia sweetening components except the rebaudioside A or with an enzyme obtained from the fungus, to give a stevia sweetener comprising rebaudiside A, stevioside and decomposition products of the stevia sweetening components except the rebaudioside A, preferably containing ≥5.5pts.wt. rebaudioside A based on 1pt.wt. stevioside.

Stevia sweetener and production thereof

PURPOSE: To obtain the subject sweetener free from sharp taste, odorless, white and water-soluble powder by blending rebaudioside A extracted and purified from plant stevia, stevioside and a specific compound measured by a highperformance liquid chromatography device. CONSTITUTION: The objective sweetener containing (A) rebaudioside A and (B) stevioside which are prepared by extraction and purification from raw leaves of plant stevia having the blending ratio of the component A and component B of preferably 1, 4 to 15 and recrystallization from water and/or 1 to 3C lower alcohol and (C) a compound showing ≤2.5 minutes retention time when measured by a high performance liquid chromatography through a Lichrosorb(R)-NH 2 column, in the volume ratio of CH 3 CN and H 2 O of 8:2 at 2ml/minute flow velocity at 200nm measurement wavelength.

Improved stevia sweetener, its improvement, food and drink or drug using same sweetener

PURPOSE:In treating an aqueous solution of stevioside, etc., with a specific enzyme, to produce rebaudioside A in extremely high conversion ratio while suppressing formation of by-products, by adding an organic solvent or a specific enzyme to the aqueous solution. CONSTITUTION:In converting stevioside into rebaudioside A by treating an aqueous solution containing both a beta-1,3-glucosylsaccharide compound and stevioside with an enzyme having beta-1,3-glucosyl transition activity produced by a bacterium, the aqueous solution incorporated with an organic solvent and/or a beta-1,3-glucanase of exotic type or separately treated. One or more solvents selected from acetone, ethyl acetate, methyl ethyl ketone, hexane, dimethyl sulfoxide, dioxane, thioglycol, propylene glycol, methyl phthalate, methanol and ethanol are preferable the organic solvent.

Production of rebaudioside a

PURPOSE:A bacterium belonging to Nocardia, which assimilates methanol and produces vitamin B12, is cultured in a medium containing methanol as the main carbon source, thus producing industrially inexpensive vitamin B12 that is an essential nutrient and a remedy for pernicious anemia. CONSTITUTION:A bacterium belonging to Nocardia, which assimilates methanol and produces vitamin B12, such as Nocardia methanophylus, FERM-4374, is cultured in an enriched medium at a temperature of 35-43 deg.C and a pH of 6.5-7 with an adequate addition of methanol during the cultivation for 1-5 days and the vitamin B12 accumulated in the cells is extracted. The amount of vitamin B12 produced largely depends on the concentration of cobalt in the medium and reaches the maximum when cobalt chloride hexahydrate exists at the concentration of 5mg/l in the medium.

Production of vitamin b12

PURPOSE: To improve the taste of stevia sweetener, by converting stevioside microbiologically to β-1,4-glucosylstevioside. CONSTITUTION: An aqueous solution containing 0.1W10wt% stevioside and 0.1W 30wt% β-1,4-glucosylsaccharide compound (a saccharide compound having β-1,4 bond of glucose, such as cellobiose, cellulose, partially decomposed cellulose, etc.) is made to react with yeast belonging to Rhodotorula genus (e.g. R. minuta IFO- 1540, R. marina IFO-1421, etc.) or an enzyme derived therefrom (e.g. β-1,4-glucosyltransferase) at 3W10pH and 20W70°C to obtain the objective β-1,4-glucosylstevioside.
