Bioconversion of sucralose-6-acetate to sucralose, an artificial sweetener has been carried out using Arthrobacter sp. (ABL) and Bacillus subtilis (RRL-1789) strains isolated at IIIM, Jammu, India. Biotransformation of sucralose-6-acetate to sucralose involves use of microbial whole cells, immobilized whole cells and immobilized whole cell bioreactor. Immobilized whole cells packed bed reactor has shown much superior biotransformation process in aqueous system using green technology, where purification of the final product is not required. The final sucralose bioproduct was directly concentrated under vacuum to get white crystalline powder. The immobilized whole cell bioreactor was used for more than three cycles continuously, thus provided much cheaper, less time consuming and easy down streaming process. Moreover, the method does not require any purification steps, which is otherwise requisite for presently available methods for sucralose production, resulting in even lower cost of overall process.
Recrystallization method of sucrose-6-acetate and applications thereof
-
Paragraph 0052; 0053; 0058, (2017/09/01)
The invention discloses a recrystallization method of sucrose-6-acetate, and applications thereof. The recrystallization method comprise following steps: a solvent is added into a sucrose-6-acetate mixture obtained via sucrose esterification; and stirring, dissolving, filtering, and drying are carried out so as to obtain sucrose-6-acetate, wherein the solvent is a mixture of a nitrile solvent and an ether solvent. The recrystallization method is capable of increasing sucrose-6-acetate purity, and reducing adverse influences on subsequent chlorination.
Deacylating method of sucralose-6-acetate
-
Paragraph 0013; 0014, (2016/12/01)
The invention discloses a deacylating method of sucralose-6-acetate, comprising the following steps: adding sucralose-6-acetate into methanol solution of sodium methylate, reacting at 58-62 DEG C for 3-5 hours, vacuum distilling and recycling methanol, and washing obtained solid with ethyl acetate to obtain sucralose. Compared with existing deacylating methods of sucralose-6-acetate, the method of the invention can be used to provide significant deacylating effect, and the yield of sucralose after deacylating is up to higher than 85%.
