4a17 | Kerry Ingredients and Flavours | Alpha-galactosidase EC 3.2.1.22Endo-1,4-beta-glucanase EC 3.2.1.4 | - Additive compositionPreparation of alpha-galactosidase produced by Saccharomyces cerevisiae (CBS 615.94) and endo-1,4-beta-glucanase produced by Aspergillus niger (CBS 120604) having a minimum activity of:
- 1000 U alpha-galactosidase/g,
- 5700 U endo-1,4-beta-glucanase/g.
Solid form - Characterisation of the active substancealpha-galactosidase (EC 3.2.1.22) produced by Saccharomyces cerevisiae (CBS 615.94) and endo-1,4-beta-glucanase (EC 3.2.1.4) produced by Aspergillus niger (CBS 120604).
- Analytical methodFor the determination of:
- alpha-galactosidase: colorimetric method measuring p-nitrophenol released by action of alpha-galactosidase from p-nitrophenyl-alpha-galactopyranoside substrate,
- endo-1,4-beta-glucanase: colorimetric method measuring water soluble dye released by action of endo-1,4-beta-glucanase from azurine-crosslinked barley glucan substrate.
