ActiveDetermination of the activity of beta-galactosidase—Spectrophotometric method
β-半乳糖苷酶活性检测方法 分光光度法
Application Summary AI generated
This standard specifies a spectrophotometric method for determining the activity of beta-galactosidase, an enzyme commonly used in the food and dairy industries. It is applied in quality control and research laboratories to measure enzyme activity in products like lactose-free milk, probiotics, and enzyme preparations. The method relies on the enzymatic hydrolysis of a chromogenic substrate, with absorbance measured at a specific wavelength to quantify activity.
