Optimization of kestose production by a Saccharomyces cerevisiae invertase exhibiting selective transfructosylation

ScINV exhibits selective kestose production without formation of higher-degree FOSs. Although partial peak overlap limits single-step recovery, purification using XA2004-30-Ca resin provides a promising basis for scale-up. Coupling this approach with continuous simulated moving bed technology may improve process efficiency and industrial feasibility. © 2026 Society of Chemical Industry.
