Methods for recombinant production of steviol glycoside and compositions containing steviol glycosides are provided herein.

Disclosed are steviol glycosides referred to as rebaudioside V and rebaudioside W. Also disclosed are methods for producing rebaudioside M (Reb M), rebausoside G (Reb G), rebaudioside KA (Reb KA), rebaudioside V (Reb V) and rebaudioside (Reb W).

A process for preparing rebaudioside M is disclosed. The process includes: a step of subjecting rebaudioside C (RC) that is adopted as a substrate and a chemical compound R1 to a substitution reaction under the action of silver carbonate to obtain an intermediate Ac-RM; and a step of performing hydrolysis to obtain the product rebaudioside M (RM). By the manner, the process has characteristics of low raw material cost, mild reaction conditions, convenient purification, simple operation, good product quality, high yield, no generation of toxic harmful compounds in the whole process, and good environment protection effects, and is suitable for industrial production.

The invention relates to a rebaudioside M purification method with the stages of crude extraction and subsequent refining treatment. The crude extraction stage comprises the following steps: a feed solution flows through eight macroporous absorption resin columns connected in series, and is absorbed sequentially; staged ethanol desorption is carried out, and analysis is carried out; an eluent is subjected to reduced-pressure concentration under high temperature; and an obtained solid is subjected to vacuum drying, such that crude rebaudioside M is obtained, wherein a crude rebaudioside M mass content reaches 25-35%. The subsequent refining treatment comprises the following steps: a mixed solvent is heated; the crude rebaudioside M is dissolved into the mixed solvent, such that a solution is formed; the temperature is reduced to normal temperature; standing and intermittent stirring is carried out; the product is allowed to stand for several hours, and solid-liquid separation is carried out; and the obtained solid is dried, such that refined rebaudioside M is obtained. The refined rebaudioside M content can be higher than 95%. The sweetness of the rebaudioside M is more than 300 times that of cane sugar. The sweetness is more long-lasting than that of cane sugar, and causes no bitter after-taste. The mouthfeel is closer to white sugar, and mouthfeel and taste quality are good. Rebaudioside M is an ideal natural sweet additive.
