## Abstract

Various ingredients and compositions are prepared from Stevia rebaudiana Bertoni plant. The compositions can be used as bulking agents, and sweeteners in foods, beverages, cosmetics and pharmaceuticals.

## Claims

### Claim 1

A tabletop sweetener composition, consisting essentially of:
stevia-derived microcrystalline cellulose ingredient as a sole bulking agent; and
a steviol glycoside sweetener;
wherein the tabletop sweetener is in dry powder form, contains no non-stevia based ingredients, and wherein the stevia-derived microcrystalline cellulose ingredient is made by a process comprising the steps of:
(a) removing water-insoluble components from a stevia biomass;
(b) incubating the water-insoluble components in an alkaline solution to produce a pulp;
(c) washing the pulp to obtain a washed pulp;
(d) bleaching the washed pulp to obtain a bleached pulp; and
(e) separating cellulose from the bleached pulp.

### Claim 2 (depends on 1)

The sweetener composition of claim 1, wherein the process further comprises the steps of:
(f) depolymerizing the cellulose to obtain a depolymerized cellulose;
(g) washing the depolymerized cellulose to yield cellulose crystals; and
(h) suspending the cellulose crystals in water and spray-drying to yield the stevia-derived microcrystalline cellulose ingredient.

### Claim 3 (depends on 1)

The tabletop sweetener composition of claim 1, wherein the sweetener composition is prepared by the following steps:
providing a solution of the steviol glycoside sweetener;
suspending the stevia-derived microcrystalline cellulose ingredient in the sweetener solution to obtain a mixture;
spray-drying the mixture to obtain the whole stevia plant tabletop sweetener composition.
