For the specific measurement of β-amylase in malt flour. Content: 100/200 assays per kit
 

Colourimetric method for the determination of β-Amylase in
cereal grains, malt, food, beverages and fermentation products

Principle:
(β-amylase)
(1) G₃-β-PNP + H₂O → G₂ + G-β-PNP

(β-glucosidase)
(2) G-β-PNP + H₂O → D-glucose + PNP

(alkaline solution)
(3) p-Nitrophenol → phenolate ion (yellow colour)
Note: PNP = 4-nitrophenol

Kit size:                            100 / 200 assays
Method:                            Spectrophotometric at 400 nm
Reaction time:                  ~ 10 min
Detection limit:                 0.05 U/mL of sample solution
