Use the value for A 3cc in the calculation of ΔA lactose below. Determine the absorbance difference caused by hydrolysis of lactose (A 3cc — A 2) for both blank and sample. Subtract the absorbance difference of blank from the absorbance difference of sample, thereby obtaining ΔA lactose.
22 Μαΐ 2024 · This chapter explores lactose hydrolysis, emphasizing conventional techniques and the noteworthy immobilization of β-galactosidase on polymeric matrices to enhance the process.
1 Ιουλ 2021 · Measurement of lactose and lactose hydrolysis products (i.e., glucose and galactose) in low-lactose products is important for lactose-intolerant consumers (van Scheppingen et al., 2017). This is particularly important in lactose-reduced and lactose-free milks and dairy-based beverages.

1 Μαρ 2021 · Currently, the main industrial process for lactose-reduced or lactose-free milk manufacturing is usually characterized by the enzymatic hydrolysis of lactose through the addition of soluble free β-galactosidase (commonly known as lactase) ( Harju, Kallioinen, & Tossavainen, 2012 ).
Enzymatic lactose hydrolysis can be used in production of lactose-free dairy foods, and as one method to increase the sweetness of certain products (e.g., yogurts), as the glucose–galactose mixture resulting from the hydrolysis reaction is at least 3× sweeter than the original lactose solution.
In the process of hydrolysis, the disaccharide lactose is converted, either chem ically or enzymatically, to its two component monosaccharides, glucose and galactose. This technique can be applied to all lactose-containing fluids, including milks, wheys and permeates from ultrafiltration of milk or whey.
