Analytical methodFor the determination in feed additive of:- endo-1,3(4)-beta-glucanase in the feed additive: colorimetric method based on the enzymatic hydrolysis of glucanase on the barley beta-glucan substrate at pH 7,5 and 30 °C,
- endo-1,4-beta-glucanase in the feed additive: colorimetric method based on the enzymatic hydrolysis of cellulase on the carboxylmethylcellulose at pH 4,8 and 50 °C,
- alpha-amylase in the feed additive: colorimetric method based on the formation of water soluble dyed fragments produced by the action of amylase on azurine cross-linked starch polymer substrates at pH 7,5 and 37 °C,
- endo-1,4-beta-xylanase in the feed additive: colorimetric method based on the enzymatic hydrolysis of xylanase on the birchwood xylane substrate at pH 5,3 and 50 °C.
For the determination in premixtures and feedingstuffs of:- endo-1,3(4)-beta-glucanase: plate test method based on the glucanase diffusion and the subsequent decolouring of the red agar medium due to the beta-glucan hydrolysis,
- endo-1,4-beta-glucanase: colorimetric method based on the quantification of the water soluble dye fragments produced by the action of cellulase on azurine cross-linked water insoluble HE-cellulose substrate,
- alpha-amylase: colorimetric method based on the formation of water soluble blue fragments produced by the action of amylase on azurine cross-linked insoluble blue-coloured starch polymer substrates,
- endo-1,4-beta-xylanase: colorimetric method based on the quantification of water soluble dyed fragments produced by the action of xylanase on azurine cross-linked wheat arabinoxylan.
