Glycoside product biosynthesis and recovery

A method for producing a steviol glycoside product, comprising:

• converting a steviol glycoside substrate to a steviol glycoside product comprising one or more of Reb M, Reb D, Reb E, Reb B, and Reb I, the steviol glycoside substrate converted to the steviol glycoside product by enzymatic transfer of one or more sugar moieties in a cell-free reaction or in a microbial culture;
• and
• recovering the steviol glycoside product from the reaction or culture, the recovering comprising:
• adjusting the pH of the reaction or culture to a pH in the range of about 2 to about 4 or about 9 to about 12, and raising the temperature to about 50° C. to about 90° C., followed by enzyme or biomass removal by centrifugation to thereby prepare a clarified broth comprising the steviol glycoside product;
• and
• isolating the steviol glycoside product by crystallization.
