Abstract: A method for purifying Reb M includes preparing a crude mother liquor/Stevia rebaudiana primary extract, passing a solution of this primary extract through a multi-column system including a plurality of columns, in series, packed with a porous adsorbent resin to provide at least one column having adsorbed Reb M and eluting fractions with Reb M content from a final/last column in the series to provide an eluted solution with Reb M content.

Abstract: A natural sweetener composition comprises a blend of Stevioside extract and Rebaudioside A extract, wherein the ratio of Rebaudioside A extract to Stevioside extract is between about 12:1 to about 1:12 and the purity of both extracts is from about 60% to about 97.5%. The sweetener composition may further include sweet sugars and non-natural sugars.

Abstract: Natural steviol glycosides sweetener compositions comprise a blend of Rebaudioside C extract and at least one of Rebaudioside A extract and STV extract including methods for producing the same and uses thereof in foods, beverages, functional foods and nutraceuticals.

Abstract: A process for producing a natural sweetening enhancer composition comprising at least an Rebaudioside C (RC) extract, said process comprises the steps of preparing a saccharide mother liquor comprising an RC mass content of at least 15%; preparing feed liquid from about 8-25 mg/L of the mother liquor; flowing feed liquid through a porous adsorption column, having a pore size of between about 0.001 to 0.2 micron, and at a flow rate of between 25 to 35 L/m2h and at a pH of between 6 to 8; eluting RC extract with alcohol, said RC extract having a mass concentration of at least 10%; fractionally collecting eluate based on chromatographic critical point for RC extract; concentrating the RC extract and drying the extract so formed. Another process for preparing a crude RC extract which comprises the steps of preparing a saccharide mother liquor into a feedstock solution with a mass concentration of about 0.
