4a17 Kerry Ingredients and Flavours Alpha-galactosidase(EC 3.2.1.22)Endo-1,4-beta-glucanase(EC 3.2.1.4) 
Preparation of alpha-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), solid form, with a minimum activity of:


— 1 000 U alpha-galactosidase/g:
— 5 700 U endo-1,4-beta-glucanase/g.

Alpha-galactosidase produced by Saccharomyces cerevisiae (CBS 615.94) Endo-1,4-beta-glucanase produced by Aspergillus niger (CBS 120604)

Determination:


— colorimetric method measuring p-nitrophenol released by action of alpha-galactosidase from p-nitrophenyl-alpha-galactopyranoside substrate,
— colorimetric method measuring water soluble dye released by action of endo-1,4-beta-glucanase from azurine-crosslinked barley glucan substrate.
 Laying hens — 100 U alpha-galactosidase — 
1. In the directions for use of the additive and premixture, indicate the storage temperature, storage life, and stability to pelleting.

2. 

— 100 U alpha-galactosidase/kg
— 570 U endo-1,4-beta-glucanase/kg.

3. For safety: breathing protection, glasses and gloves shall be used during handling.
