A process for producing a low-calorie table top tablet, comprising:
- admixing a natural sweetener;
- wherein the natural sweetener comprises sweet glycosides, wherein the sweet glycosides are produced from Stevia rebaudiana leaves by a method;
- and
- wherein the method comprises the following steps:
- a) drying Stevia rebaudiana leaves;
- b) treating the dried Stevia rebaudiana leaves with water to extract sweet glycosides, wherein a leaves-water mixture is formed;
- c) filtering the leaves-water mixture to obtain an aqueous filtrate;
- d) directly treating the aqueous filtrate with calcium hydroxide or calcium oxide to raise the pH of the aqueous filtrate to about 10;
- e) directly neutralizing the treated aqueous filtrate with trivalent iron chloride;
- and
- f) filtrating the neutralized aqueous filtrate to obtain a filtrated aqueous filtrate, and evaporating the filtrated aqueous filtrate to dryness to obtain purified sweet glycosides;
