Document Type and Number:
WIPO Patent Application WO/2023/038057
Kind Code:
A1
Abstract:
Provided is a lactase preparation that has excellent lactose degradation action in milk. The lactase of one aspect of the present invention has lactase activity described by one or a combination of (1)–(6). (1) The amount of lactase protein added to milk to make the remaining lactose concentration no more than 0.1% after 16 hours at 10°C is no more than 15.1 mg/L. (2) The amount of lactase protein added to milk to make the remaining lactose concentration no more than 0.01% after 16 hours at 10°C is no more than 30.2 mg/L. (3) The amount of lactase protein added to milk to make the remaining lactose concentration no more than 0.1% after 24 hours at 10°C is no more than 10.1 mg/L. (4) The amount of lactase protein added to milk to make the remaining lactose concentration no more than 0.01% after 24 hours at 10°C is no more than 15.1 mg/L. (5) When the lactase is added to milk in an amount that makes the final concentration 1.4 LYU/ml, the remaining lactose concentration after 24 hours at 10°C is no more than 0.1%. (6) When the lactase is added to milk in an amount that makes the final concentration 2.1 LYU/ml, the remaining lactose concentration after 24 hours at 10°C is no more than 0.01%.
